A beautiful day!

I got up this morning for my daily walk – well, actually, I don’t do a daily walk, anymore.  Saturday and Sunday, I get up early and go for a walk. Monday through Friday, I spend a half hour on my elliptical machine in the basement – but I digress.

I woke up this morning to the beginnings of a beautiful day!  Yesterday was positively tropical, hot and humid, with the threat of severe thunderstorms and tornadoes all day. One minute it would be sunny, the next it was dark and threatening. While other areas in the North East were not so lucky, I praise God, that in South Plainfield, all we got was some really heavy rain from about 5:00 to 6:00 PM yesterday evening.  After that, the temperatures dropped, dry air moved in and you can honestly say that today is one of the “Ten Best of the Year”.

Weather issues aside, the object of this post is to relate that I did something yesterday that I have not done in a very long time – about 9 years to be exact.

I made a contact using SSB.

Yes, I know – totally out of character; but I did it and surprised myself in the process.  After mowing the lawn yesterday, I had a little bit of down time, so I went down to the shack to spend a little bit of quality time behind the rig.  Alas, 12 Meters, 15 Meters and 17 Meters were a vast wasteland.  20 Meters was not bad; but had very little activity in the CW portion of the band.  So I decided to switch the K3 over to USB, and went “up” the bad to see if perhaps there were any special event stations doing their thing.

Didn’t hear any of those, either.  But I was hearing a lot of loud European stations working the WAE contest. So I thought to myself, “I wonder if one might hear me …….. hmmmmm”.  I twiddled the dial looking for a particularly loud one – there were a good number of them.  Then I heard a call sign that sounded interesting – 3Z2X.  AC log informed me that it was Poland.  All the better, the country that my ancestors came from!

Using my noodle, I pumped the K3 up to 10 Watts – still QRP by definition (I may be a little crazy; but I’m not insane – SSB and QRO? No way!). Then, I picked up that funny looking little box that you speak into – I think it’s called a microphone and pressed the button thingy on the side.  Announced my call sign and actually heard him call me back!  I gave the contest exchange, got his and then sat there kind of amazed.  10 Watts via SSB all the way to Poland – and he heard me!  We spoke to each other, exchanged information and said good-bye. It worked. I was amazed.

I made a few more and it was fun but it wasn’t enough to convert me from being a dyed-in-the-wool CW op.  But it did hold out hope for me that, in the future, I may be able to work Special Event stations that choose not to have CW as one of the modes that they employ.  It also encouraged me to maybe dip a toe into the pool when the QRP-ARCI holds their annual QRP SSB Sprint.  I never participated in one of those before.  This year just might be different.

FT-790R, 1W of Forlorn Hope? Part II


I’m treasuring my multimode, single band transceiver of yesteryear. They really ‘don’t make them like that any more’. When the FT-790R was manufactured, the UK still happily built cars that broke down and industrial action was a continuing popular pastime. Thank goodness the Japanese manufacturing success story was at its zenith.

In my previous blog, FT-790R, 1W of Forlorn Hope? I outlined my trepidation, my dreams and anticipated joy of achieving hilltop 70cm SSB contacts over phenomenal distances. This was in the face of an antagonist old-timer who thought a little too much RF had leaked into CPU of my head. So what was the reality?

Since taking delivery of the ‘790, I’ve managed to test most of the functions. With a radio of that age I shouldn’t have been surprised that the front panel illumination bulbs have long since ruptured their once-bright filaments, probably in the early 1990’s. A simple removal and refit of the battery tray, which holds eight ‘C’ cells was required to reconnect the internal power.


Powered by 8 'C' cells
Straight away, I connected a spare telescopic antenna for 2m to the front panel BNC and gave a call on FM. I enjoyed two great local contacts with stunning audio quality. Excellent audio reports came back too. Two quick tests with local station John GW4ZPL confirmed that SSB was working fine, albeit a little off frequency with his TS-2000 shack-in-a-box. Then we tried CW (my first CW attempt, ever). Apparently John hadn’t heard ‘chirp’ like mine since working Russian stations in the 1980’s! Luckily the operation manual comes with a full schematic diagram. I’ll have a look and see if a key click filter is misbehaving, for example.

Realistically speaking, I do know that a random 1W call on 70cm SSB is unlikely to attract an answer under normal conditions. My plan was to get to a modest local hilltop with a small beam antenna. If there was any tropospheric enhancement or lift, all the better. Unfortunately, the Welsh weather of late prevented this. Following the advice of Tim, G4VXE, a competition evening would give me a fighting chance.

Casually having a chat on D-STAR the other evening, someone mentioned that a 70cm activity evening was due to start in around half an hour at 20.00. No time to get up a hill and where the heck was my BNC to SO239 adaptor when I needed it to hook up my homebrew 9 element beam? So, if you can picture me leaning out of the upstairs window with a small, non-resonant, telescopic antenna pointing out at a jaunty angle, then this was my big chance. My only chance, so far.


I scanned the SSB portion of the band. Nothing. I twiddled the telescopic antenna and re-scanned. Nothing. But then, a quick call in a clipped English tone and a GD (Isle of Man) callsign. After a couple of failed attempts, antenna adjustment, more leaning out of window, the received signal came up to 5,9. The other station adjusted to my offset frequency and SUCCESS! - Gave me a 5,4. He said he was using 400W and a 23 element beam that wasn’t even pointing my way. The distance was around 73 miles or 117km, admittedly mostly over a great sea-path.

He’d been calling out rather robotically but had a chuckle and warmly wished me 73 when he heard about my operating set up. I forgot his callsign in the excitement and my bemused YL heard a whoop of joy from downstairs.

Anglesey to the Isle of Man
For every person that has told me that an FT-817ND would be the ideal rig for me (and it would), there has been another that has regretted getting rid of their FT-2/6/790R. My FT-790R is a solid, brick-like joy to own. When I get up to a hilltop to try it out again, I’ll be supremely hopeful!




Is there an inexpensive kit for the Technician 10M phone band?

In the comments for the kit roundup, a reader asked me about this, so I looked through the list again, and found the lowest priced kit available that will cover at least a portion of the 28.300 to 28.500 range. The YouKits TJ2A seems to be the only choice, but only after adding the accessory crystal pack #2.  He pointed out the inexpensive MKARS80 as an example of a great SSB kit for very little money, but not covering a band available to a technician-class ham.  On a side note, I wonder if it is possible to create an MKARS10?  Here is my reply:

I’m not sure why there aren’t more SSB kits for 10 meters. In the list here you can try the Youkits TJ2A (http://youkits.com/ or the eBay store) and build it for 10 meters by ordering crystal option package #2. They only show one optional package on the website, but two in their eBay store for some reason.  According to their specs this will give you 28.326 – 28.420.  You might have luck contacting them directly and trying to order one with the correct BPF components for 10 meters with the initial kit package and save a few $$.

Another suggestion is to step up to general. I started studying as soon as I got my tech, and took the test about 6 weeks later. Tech-to-general is a pretty easy jump (mush easier than general-to-extra) and will give you the ability to use some of these other kits (like the aforementioned bargain-basement MKARS80).

A third option is to pick up a used Radio Shack HTX-10 or HTX-100 rig on eBay or at a hamfest. I have a Magnum-257 in the car (same rig as the HTX-10) that I picked up for $125. That rig with a modified 11 meter whip has been heard in Europe, Africa, and all over South America from here with 25 watts. In fact, my first contact on HF as a new ham was with France! I wish that good fortune on any new ham. It certainly got me interested in getting more great contacts.

Whatever path he chooses I’m sure it will be enjoyable.  Once you make that first contact you catch the fever, and can’t wait for more.

EDIT:  Andrew AC8JO reminded me about the Softrock RX/TX SDR kits, which can be built with 17, 12, and 10 meters at 1 watt. (you select the bands when you build, the kit comes with parts necessary for all). The kits are $89 when available. See http://www.kb9yig.com to order, or the Yahoo Group Softrock40 for announcements of upcoming availability or units to purchase.  I hear that it is a moderately difficult build for a newbie, but there is PLENTY of info online to assist you.

Happy New Year to all! I’m back after a week’s vacation for the holidays and feeling very rested. Tyler, N7TFP on the other hand, has been busy, busy, busy. I don’t know about the holidays, but the videos he’s been cranking out are great! Here’s another one for you!I have been saying this with the last couple videos that getting back to basics are great for the veterans on the air, and these are great tutorials for those just joining or recently joined the hobby. In this one, Tyler shows how to set the proper mic gain on your SSB tranceiver. Without any more fanfare, heeeeeeeere’s TYLER!

73.
