Here Comes The Novice Rig Roundup (NRR) 2020!
One of the most enjoyable operating events of the year is fast approaching -- the Novice Rig Roundup or 'NRR'. Technically, it is a contest, but I have the feeling that most participants think of it as just a lot of fun and a nice opportunity to hear and work some of the great old 'classics' of the past -- rigs that were used when they were teenage Novices or rigs that they could only drool about owning, back in those formative years when they each discovered the magic of radio.
Once again the bands will be alive with the sounds of Heath AT-1s, DX-20s, DX-35s, DX-40s and DX-60s, Johnson Adventurers, Eico 720s, Drake 2NTs, Knight T-50s and T-60s, Ameco AC-1s and of course, an endless variety of lovingly-constructed homebrew delights and ... a full week plus two weekends to celebrate the 'good old radio days' of their teen years, as many of us remember them.
The dates to remember are 0000 UTC March 7 to 2359 UTC March 16 and this multi-day opportunity is, for me, what makes the NRR so enjoyable. With a nice diversion from the usual 'contest frenzy' associated with standard weekend operating events, the NRR can be enjoyed throughout the week, whenever you choose to participate. If last year's operating patterns continue, you should find activity at any time of the day ... and even more as sunset arrives.
With the fast-approaching solar minimum, we will be hard-pressed to relive the glory days of worldwide 15m propagation, but many transcon contacts were made during last year's event thanks to some well-timed solar activity! With a little luck and, hopefully, a well-timed solar flare, we may get lucky! If you operate during the daylight hours, please get on 15m and give it a shot ... and be sure to announce your activity on the NRR's sked and chat page here, so that others will know where to find you, especially if you are rock bound in true Novice fashion. With our present spotty conditions, we need all the help we can get and the sked page proved a very valuable asset during last year's affair.
Although technically not required, if you plan to participate it's best to obtain your own NRR number, which is an easy 30-second process.
Additionally, there is an online logger where participants can post their daily log. The nifty logger also keeps track and figures out your score as it goes and no 'after contest' log needs to be submitted. If you plan on submitting a log, the logger is a requirement. The logger will also require you to set up a 'log-in' and once again, a simple 30-second process will take care of that from here. If you used the logger last year, you will have to set it up again for this year as the old system has been changed.
Stations may run either crystal-control or VFO or can switch between either method ... the online logger will keep track and score things appropriately.
All of the rules and information can be found on the NRR's excellent website. As well, the soapbox comments and station pictures from last year's NRR may provide the inspiration that you need to spark-up your own activity in this year's event ... from what I can tell, this year will be bigger and busier than ever!
There is also a dedicated NRR Group, often the source of much valuable discussion but there is a now HUGE group of great NRR chat and activity now on Facebook's NRR Group here. I avoided Facebook for many years and have now discovered that it is an excellent forum for real time chat and information exchange ... one can still choose to maintain a very low profile and avoid unwanted interaction if set up correctly.
In 2017 I ran my homebrew Longfeller in the (now eliminated) QRP category, and had a ton of fun. You can read about it here. Last year, I refurbished a nice Drake 2NT that had been gathering dust in the basement for over 25 years and ran it during the 2018 NRR. You can read about my activity and some of the rigs encountered during last year's fun here.
If you have access to the web while operating, be sure to bookmark and check into the NRR's realtime chat page. Many ops that are crystal controlled will announce their operating frequencies, making it easier for you to find them ... sometimes way up or down from the normal NRR watering holes of ~ 3550 - 3650 kHz, 7100 -7125 kHz, 21.100 - 21.150 MHz and 28.114, 28.120 MHz ... and don't forget to check the colorburst crystal frequency of 3579!
'CQ'ers should always remember to tune up and down the watering hole for replies from other NRR stations that may be crystal controlled and not able to answer you on your own frequency!! This is extremely important and a real reminder of what was common practice back in the Novice days.

You still have time to get that old clunker on the air but if that's not possible, you can join the fun with your modern rig as well ... all are welcome to jump in and have a great week of radio-fun. I think you will be surprised, just as I was last year, how good some of these old classics can sound ... and you'll hear some great bug-fists as well.
Need more inspiration? ... here's a summary of my own experience of the 2018 NRR:
***********************
The NRR once again provided many notable highlights over the nine day event.
Almost topping the list was just experiencing the variety of old classics and hearing how well almost all of them sounded. Numerous Knight T-60s, Drake 2NTs, Heath DX-40s, Johnson Adventurers and Eico 720s, along with a nice variety of homebrew MOPAs and one-tube power oscillators graced the nightly airwaves. These oft-forgotten shelf-queens always seem to develop super-powers, far beyond their expectations, when the NRR rolls around!
I was really surprised to work so many T-60s, a small and inexpensive 60 watt transmitter kit from 1962 using a popular 6DQ6 television sweep tube ... one never expected to achieve such RF greatness! I was very impressed with every one that I heard.
What radio-struck pre-Novice teen, dreaming about getting on the air, could resist a clever ad like this.
Scott, KA9P's 80m T-60 signal sounded as sweet as it looks in his 2018 setup, paired with his Heathkit HR-10B inhaler.

Right up there with the plethora of T-60s was the Drake 2NT, another great sounding radio and also my choice for this year's event. My summer refurbishing project, described here, proved a worthy companion, although my much-treasured VF-1 VFO's short term drift probably had my 2NT getting red in the face whenever I took her off of crystal control to scurry around the band, seeking out the CQ'ers. I've had a love-hate relationship with the VF-1 ever since buying my first one back in '63!

Yet another 2NT packed a powerful punch from West Virginia, keyed by Dave, W3NP, when we exchanged 579 reports on 40m, 45 minutes before sunset.
W3NP - 2018 NRR setup |
I made three contacts on 15m this year: W5IQS in Texas, K2YWE in Maryland and WN4NRR in Florida, whose S9 reply to my 'CQ NRR' just about took my head off ... what a nice surprise to hear the booming signal from Bry's 2NT powerhouse. Dan, K2YWE, was no slouch either, as his Globe Scout was music to my ears when his signal quickly rose out of the noise just long enough to make the coast-to-coast journey. If the predictions for future solar cycles become reality, there may be many more NRRs before we experience the magic of 15m once again.
K2YWE's Globe Scout and Adventurer were worked on all three bands! |
My NRR exchanges with George, N3GJ (KA3JWJ) in Pennsylvania, truly demonstrated just how well the low bands were performing. More than an hour before my local sunset, I responded to his 569 40m 'CQ NRR' only to learn that his signal, now reaching a solid 579, was coming from an original Ameco AC-1! This one-tube crystal-controlled power oscillator has, over the years, reached Holy Grail status among many amateurs. Originals are guarded like precious jewels and handed down from father to son ... or in George's case, from uncle to nephew!
N3GJ and his all powerful original AC-1 |
Heathkits were plentiful too, with the DX-60 seeming to be the rig of choice, often paired with the matching HG-10 VFO. Both Mark, VA7MM and Gary, W8PU, packed a wallop with these fine examples.

But it wasn't just DX-60s representing Benton Harbor engineering in the NRR. All of these neat old Heaths made it out to the west coast, sometimes on both 40 and 80. KN8RHM's (Rick) HW-16 made it here on 40m with a solid signal almost every night, while KE4OH (Steve) sported a modernized DX-20 in the form of Heath's HX-11. Steve even received the highly-treasured 'OO' report for his NRR chirp ... good job!

Rich, WN7NRR / AG5M operating in nearby Washington state put some of his 44 crystals to work with his HW-16 ... that's some collection!

Howie, WB2AWQ in Reno, was using his homebrew pair of 807s, driven with a Millen 90700 swing-arm VFO from 1945. Most shacks worldwide, including the Novices, found plenty of use for the 807 as they were dirt-cheap in the post war surplus market. The filament has a beautiful illumination and if a bit gassy as most are by now, emit a wonderous blue glow with each press of the key.

I finished up the NRR with 123 contacts, a lot better than last year's event when I was running the Longfeller at 5 watts.
As indicated on the NRR website, this is "more of an EVENT than just a typical contest ... once again taking our OLD ham radios off the shelf and putting them to use again! "
See you in the 2020 NRR!

Harry’s homebrew 6AQ5 crystal oscillator (Feb ’55 Popular Electronics) and Hallicrafters S-53, pictured above, allowed him to work the world back in the amazing radio days of Cycle 19. Let’s relive some of that excitement in the closing days of Cycle 24 … in the NRR!

Monday’s ‘NRN’ CW Fun
My homebrew Ameco AC-1 clone |
A weekly CW operating activity that seems to be growing in popularity is the Monday “NRN”.
The NRN get-togethers are an offshoot of the annual “NRR” or Novice Rig Roundup. Monday’s “Novice Rig Night” gradually grew from those that wanted to see the NRR fun continue, in one form or another, without waiting an entire year for the event to roll around again.
Operating times run from sunup on the east coast to midnight on the west coast ... but basically, people just get on the air whenever they can on Monday and call “CQ NRN”. I suspect that most of the activity takes place between late afternoon and bedtime, with 40m probably seeing the most action. As winter arrives, we may see more activity on 80m but these are only my personal observations from the west coast.
Most folks are using typical Novice-era transmitters and / or receivers, with the Drake 2NT, early Heathkits, Eicos, homebrews and Hammarlunds being popular. The previous Monday I was active with my homebrew Ameco AC-1 clone, a 6V6 crystal power oscillator, at about 6 watts out. Good contacts were had with several eastern stations. There are several AC-1s around and there has been at least one suggestion of an 'AC-1 Night' ... what fun that would be as well!
For last night’s NRN, I brought out my homebrew Paraset.
Once again, good contacts were had with the easterners on 40m: W9BRD in NJ, W3NP in WV, KD2E in NJ and VE3LYX using his No.19 tank radio ... two WWII radios talking to each other in 2018, one real and one a reproduction!

Here is the formal announcement for the Monday events, with a few additional details. Hopefully you can join the fun (any rig is fair game!), next week.
My 2018 Novice Rig Roundup (NRR) Highlights
courtesy: arrl.org |
Well this year's NRR has come and gone, providing a full nine days of CW fun for those of us that love old radios.
Once again, the ether filled with signals spawned from the old classic Novice-class workhorses that many of today's 'seasoned' amateurs used in their first stations, way back in their teen years. In many respects, the NRR is as close to a real time machine that you'll find, allowing participants to experience the joys, and sometimes the frustrations, of operating CW with their favorite old rigs from the past.
For me, just like last year, the NRR once again provided many notable highlights over the nine day event.
Almost topping the list was just experiencing the variety of old classics and hearing how well almost all of them sounded. Numerous Knight T-60s, Drake 2NTs, Heath DX-40s, Johnson Adventurers and Eico 720s, along with a nice variety of homebrew MOPAs and one-tube power oscillators graced the nightly airwaves.

Condo Hamming, The NRR and Ron’s Logs

Rick, KB2NAT, describes the learning curve in his 'How To Overcome Some Condo Issues' post.
Amateurs contemplating downsizing to a restricted development or those finding themselves in a similar situation to Rick will likely soon be subjected to more noise, less space, more neighbours and an abundance of rules. Hopefully the comments of Rick and others will be helpful if this is your situation.
For many restricted hams, Mag loops appear to be a popular choice and one of the comments points to a good deal of information on building one for yourself. The Villages Amateur Radio Club (K4VRC) group's 'resources' link will provide some interesting ideas for restricted antenna builders. As well, they have put together an informational presentation, full of great antenna ideas for those contemplating ways to get on the air from antenna-restricted locations.
If you live in the USA, the 'Freedom to Display the American Flag Act of 2005' has been used by many antenna-restricted hams, to legally erect their own 'antenna flagpole'! It may be an easy route for a nice antenna system for you as well.
The 'Novice Rig Roundup' Starts Tomorrow!
Just a reminder that 9 days of CW operating fun begins tomorrow afternoon. After last year's most enjoyable event, the NRR is now one of my 'must do' operating activities. You can read all about it here.
Ron's Logs

Ron lives in the seaside city of Monterey (CA) and on most mornings he makes the short pre-dawn drive to Asilomar State Beach (CA), a spectacular location on the coast.
After stringing out his 100' wire antenna on the nearby fence posts, Ron proceeds to log and record some truly exotic stuff before heading home.
Early last Fall, before being aware of Ron's daily regime, I had visited his exact location and after watching the big sea lions playing in the surf, had drooled over the location's great DX potential, little knowing that Ron had likely packed his gear up a headed home just a few hours before my arrival! I'm sure you'll be inspired to tune around the SW broadcast bands after checking out theses Group's daily posts.
The 2018 Novice Rig Roundup (NRR)
One of the most enjoyable operating events of the year is fast approaching -- the Novice Rig Roundup or 'NRR'. Technically, it is a contest, but I have the feeling that most participants think of it as just a lot of fun and a nice opportunity to hear and work some of the great old 'classics' of the past -- rigs that were used when they were teenage Novices or rigs that they could only drool about owning, back in those formative years when they each discovered the magic of radio.

The dates to remember are 0000 UTC March 3 - 2359 UTC March 11 and this multi-day opportunity is, for me, what makes the NRR so enjoyable. With a nice diversion from the usual 'contest frenzy' associated with standard weekend operating events, the NRR can be enjoyed throughout the week, whenever you choose to participate. If last year's operating patterns continue, you should find activity at any time of the day ... and even more as sunset arrives.
With the fast-approaching solar minimum, we will be hard-pressed to relive the glory days of worldwide 15m propagation, as even last year's event proved to be tough on this band. With a little luck and, hopefully, a well-timed solar flare, we may get lucky! If you operate during the daylight hours, please get on 15m and give it a shot ... and be sure to announce your activity on the NRR's sked and chat page here, so that others will know where to find you, especially if you are rock bound in true Novice fashion. With our present spotty conditions, we need all the help we can get and the sked page proved a very valuable asset during last year's affair.
Although technically not required, if you plan to participate it's best to obtain your own NRR number, which is an easy 30-second process.
Additionally, there is an online logger where participants can post their daily log. The nifty logger also keeps track and figures out your score as it goes and no 'after contest' log needs to be submitted. If you plan on submitting a log, the logger is a requirement. The logger will also require you to set up a 'log-in' and once again, a simple 30-second process will take care of that from here.
Stations may run either crystal-control or VFO or can switch between either method ... the online logger will keep track and score things appropriately. Stations running in both Novice 1 and Novice 2 categories (probably most common), will be eligible for prizes in both modes if they make at least ten contacts using a Novice 1 station or if they work ten Novice 1 category stations.
All of the rules and information can be found on the NRR's excellent website. As well, the soapbox comments and station pictures from last year's NRR may provide the inspiration that you need to spark-up your own activity in this year's event ... from what I can tell, this year will be bigger and busier than ever!
There is also a dedicated NRR Yahoo Group, often the source of much valuable discussion.
Last year I ran my homebrew Longfeller in the (now eliminated) QRP category, and had a ton of fun. You can read about it here. This year, I have refurbished a nice Drake 2NT that had been gathering dust in the basement for over 25 years ... it's all ready to go now, but a problem with the VF-1 VFO has arisen. The combination works well on 40m and above but on 80 it's a different story. The VFO runs on 160m and it seems that the 2NT balks at the idea of doubling in the buffer stage to 80m. Unless I solve the problem, I'll be rockbound on 3579, 3550 or 3560kc. ... it was 'kilocycles' back then, which always seemed to make more sense to me than 'kilohertz'.
If you have access to the web while operating, be sure to bookmark and check-in to the NRR's realtime chat page. Many ops that are crystal controlled will announce their operating frequencies, making it easier for you to find them ... sometimes way up or down from the normal NRR watering holes of ~ 3550 - 3650 kHz, 7100 -7125 kHz, 21.100 - 21.150 MHz and 28.114, 28.120 MHz ... and don't forget to check the colorburst crystal frequency of 3579!
Of course with the large number of rockbound stations (on crystals), be sure to look above and below these frequencies. It's good practice to listen well above and below your own frequency as well, for anyone answering your CQ who may be up or down the band on crystal control. Unlike today, this was very common practice back in the Novice days!

You still have time to get that old clunker on the air but if that's not possible, you can join the fun with your modern rig as well ... all are welcome to jump in and have a great week of radio-fun. I think you will be surprised, just as I was last year, how good some of these old classics can sound ... and you'll hear some great bug-fists as well.
As indicated on the NRR website, this is "more of an EVENT than just a typical contest ... once again taking our OLD ham radios off the shelf and putting them to use again! "
See you in the 2018 NRR!
Drake 2NT And The Novice Rig Roundup (NRR)
One of this summer's radio workbench projects was to refurbish my Drake 2NT transmitter for this winter's NRR event. The 2NT was introduced in 1966 with the 'novice' ticket-holder in mind, selling for $129. It was the first and only CW-only transmitter produced by R.L. Drake.
As novice transmitters go, the 2NT was a cut above some of the others out there, boasting interesting features such as a built-in antenna changeover relay, sidetone oscillator, grid-block keying and built-in low pass filter.
The tune-up procedure was simplified as well and with Drake's reputation for quality construction, the 2NT became a popular choice for Novices and Generals alike.
My own 2NT was purchased, along with the matching 2C receiver and speaker/Q-multiplier combo over 25 years ago at a Washington state ham fleamarket. Ever since then they have been patiently sitting on the shelf, trying to catch my attention.
The motivation and much-deserved attention finally arrived this year after enjoying last winter's NRR and hearing several great-sounding 2NT's on 80, 40 and 15m CW. I operated the week-long Roundup with my homebrew 'Longfeller' at 5W output, in order to qualify for the QRP category.

I eventually ended up with 68 contacts, but at 5W, it was a challenge ... most of my many 'CQ NRR' offerings were unanswered, so it was mostly a 'search and pounce' operation. With this in mind, I soon decided that next time, I'll get the 2NT ready to go and hopefully, with a little more oomph, can attract some callers.

Rather than hunt down and purchase the individual replacement electrolytics, especially the multi-unit can capacitor which was impossible to source, I ordered the '2NT re-cap kit' from Hayseed Electronics. They supply replacement kits for several boatanchors and are able to make and stuff multi-section can capacitors to match the original size and specs ... and all at affordable prices.
After cleaning the chassis and all of the switches, re-tubing with new tubes and removing / replacing all of the electrolytics, the 2NT was ready to go. Using a crystal for excitation, the following results were obtained:
80m 103W input 75W output efficiency = 73%
40m 92W input 65W output efficiency = 71%
20m 92W input 65W output efficiency = 71%
15m 92W input 55W output efficiency = 58%
10m 92W input 50W output efficiency = 54%
Keydown voltages averaged ~520V while plate current ranged from 170-200ma. All-in-all, right on target and not bad for a 51 year old transmitter!
The 6EA8 modified Pierce oscillator in the 2NT seems particularly 'crystal-friendly', as every old style FT-243 style crystal that I tried sounded great. Even the newer ones from AF4K using a modern HC-49 crystal slab mounted inside a vintage FT-243 holder sounded great and worked perfectly.

A couple of days later, I returned to the bench to take some blog photos of the rig delivering power into the wattmeter. When I turned the 'stby' switch to 'transmit', the plate current suddenly shot up (with no keying) and the meter on my Variac supply indicated over an amp being drawn by the power transformer ... all with zero output and no crystal plugged-in!
A look at the schematic diagram revealed that with the grid-block keying system, the final amplifier's cathode is always grounded and a low voltage negative bias applied to the grid keeps the plate current cut-off until being keyed ... with cut-off bias missing, plate current will soar, along with transformer primary current. I suspected that something had gone haywire with the bias supply.
A quick check of the 2NT's printed circuit board containing the bias system components among others, indicated a discolored silicon rectifier (D5) in the bias supply. An in-circuit measurement revealed that it was indeed shorted, basically supplying raw AC across the filter capacitor and shorting out the transformer winding, quickly elevating the transformer's temperature in the bargain ... not good.
Although the diode only has to handle a small amount of current, it was mounted with a heat-producing 2W resistor straddling its top surface. As well, the phenolic circuit board was noticeably discoloured from the heat. I suspect this was the main reason that D5 eventually failed.
My 2NT was an early one, serial #670, so perhaps this parts-arrangement was re-engineered in later models. Once the diode was replaced with a much smaller modern one, of twice the rating, everything returned to normal. The last thing I would want to do at this stage is to burn out the transmitter's unique power transformer, undoubtedly impossible to replace nowadays.
The next bench project will be to refurbish and improve the stability of my Heathkit VF-1 VFO and to mate it with the 2NT.

Another small quirk noticed on my 2NT is the meter mount. My early model has the meter mounted so low that the silk-screened 'PLATE CURRENT MA.' label is not clearly visible when looking straight-on.

You can read many interesting soapbox comments and see some nice NRR station photos from the previous two events here and here, but read with caution as you could easily get hooked. I find pages like this very inspiring and they remind me of the days when QST would publish photos, soapbox comments and exacting equipment descriptions used by each section winner in the annual November Sweepstakes contest.
