Repairing a Kenwood TR9500, Part2 – TX working, SSB RX not
September 10th, 2014 | 
Author: As I suspected the microphone amplifier Q1 in the Kenwood/Trio TR9500 was indeed faulty. The replacement arrived next day and within an hour I had successfully soldered in the new 2SC2240 transistor and it now had audio on transmit.
Transmitting into a dummy load and monitoring on my FT857-D the FM transmission was fine, the SSB was okay, perhaps slightly over driven. I suspected that maybe the previous owner might have twiddled something to compensate for a failing Q1.
In the adjustments section of the service manual VR6 on the IF unit controls the SSB MIC gain. To check the settings it was a case of setting the transmitter to 432MHz and putting an audio frequency signals of 1.5kHz of amplitude 1mV and 10mV from my signal generator on to the microphone terminal, and observing the RF power output, which were the 5W and just over 10W as required. As this didn't need altering I left it alone and boxed it back up and returned it to the happy owner.
Last night was the RSGB 432MHz UKAC Contest and I was hoping to here it on the air, sadly I didn't. It now transpires that there maybe another issue with it, something I should have spotted.
I do remember something strange when doing the initial testing. Connected to a dummy load and in SSB mode the S-meter showed S9+ when in receive but with no audio, turning the RF gain control the meter dropped to S0 and normal white noise static could be heard. It received a SSB transmission from the FT857-D with no issue so I thought no more of it. Being over eager and not experienced with using different rigs I had mistakenly dismissed it and should really have read the operating manual more extensively.
The anomalous S9+ meter reading and no audio occured when the RF gain control was set to the maximum which is the normal recommended setting for operating, I'd simply turned the RF gain control to the minimum mitigating the issue.
Obviously the rigs owner had put the RF gain back to maximum and was now reporting it wasn't switching back to receive. In fact it is but nothing is being heard. Checking the service manual this morning and it appears there is an issue with the AGC circuit (description and block diagram below)
It seems the rig may well find itself back on the bench, however this repair could be more problematic!
As I mentioned it was the 432MHz UKAC last night and I had a decent night of search and pounce. Conditions were very strange, lots of fading and strangely some of the usual local operators were not heard. I was very pleased to catch some lift and made a couple of decent DX contacts in Northern Ireland, The Isle of Man, Northumberland as well as Essex and Cambridge.

RECEIVER CIRCUIT
.... The signal is picked up from the last stage of the IF amplifier (Q23), then detected and amplified to generate the AGC voltage. The AGC time constant is automatically set according to the mode : FAST for CW; SLOW for SSB. The AGC voltage is applied to IF amplifiers Q21, Q22 and Q23 (3SK73(GR)) and RF amplifier Q51. It is also used to drive the S meter.

— Andrew Garratt (@nerdsville) September 9, 2014 In a few weekends it is the National Hamfest, which is held in my home town and I hoping to pick up some bargain gear to improve my UHF set up, however from past experience that may prove difficult. Here’s a little something I came up with
This was designed to be printed on 4X6 Glossy stock and then laminated. You can jam in your portable ops bag, in case you're always forgetting the US QRP frequencies like I do.
Feel free to save the JPG as an image on your own computer and print it out, if you like. I also have it as a doc file if you'd like to edit to suit your needs. An e-mail request will get it sent to you.

I was asleep at the wheel
How did I miss this? I've had my September QST for over a week now (we Lifemembers seem to be the last to receive our QSTs!), and I must confess .... today was the first time I've given it a leaf through. I was surprised and gladdened to read a really nice op-ed piece by good friend Jim W1PID on page 101.
Jim shared his thoughts on the changing face of Amateur Radio in celebration of the ARRL's 100th anniversary, but yet focused on the things that remain the same through the changes. The joy, the excitement, the satisfaction, the fun.
Good article, Jim and I'm glad the Newington Bunch had the good sense to publish it!

Repairing a Kenwood TR9500, Part1 – The Diagnosis
A fellow SKARS club member picked up a nice condition Kenwood/Trio TR9500 70cm all-mode transceiver (circa 1980) from the Hamfest last year for not a lot of money and he hoped to use it for the UKAC contests unfortunately it proved to be faulty.
From the description of the fault and studying a downloaded service manual I suspected a relatively simple fault and saw an opportunity to acquire it and offered to buy it for the price he had paid. However I have decided to be more charitable rather than mercenary and have offered to give it a look over and repair it for him if I can.
The fault as described was the rig receives okay but on transmit there was a carrier on FM with no audio and a very quiet SSB signal. A faulty microphone had been ruled out and someone had suggested a bad connection internally. Due to the compactness of the unit and the difficulty in dismantling no one had felt confident to attempt any further inspection. I wasn't so sure this was the issue so at the last meeting I picked up the rig and currently have it on the workbench.
I want to confirm the fault first and so I connected up a dummy load and RF power meter and using the FUNCube Dongle SDR I could observe and monitor the output signal. Sure enough on FM there was a nice carrier at 10W with very faint audio, on SSB there was a small visible signal again with very little modulation. Whistling, blowing and tapping of the microphone could be seen on the waterfall... just!
I connected a switch to the Morse key input and confirmed the rig transmitted in CW with no issue.
On the block diagram there is a switchable tone burst oscillator for repeater access and the output of this is joined to the output from the microphone amp. Encouragingly the tone burst can be clearly seen and heard in the transmission again pointing to an issue with the microphone amp.
To get to the carrier unit PCB it was a simple matter of removing the bottom cover. The PCB is held in a metal frame mounted with five screws and can be lifted out, as pictured above. But before I did that I checked the continuity to the microphone socket and the 8V supply to the amplifier circuit and both were fine (see diagram below)
The poor quality image from the scanned service manual shows the bottom of the carrier unit, this is the side of the PCB visible without needing to remove it. The microphone connector is in the top left, putting an oscilloscope on the microphone input (pin1) a signal was observed, however the output (pin8) had an almost identical signal with little or no amplification. Injecting a low level audio signal from the a generator on this pin could be seen and heard in the transmitted signal. This observation together with the tone burst seemed to confirm the other audio circuitry was functioning normally and the microphone amp wasn't.
Actually removing the carrier unit PCB proved a bit tricky as it has a number of small and very secure connectors with ageing and delicate wiring, but I did manage to extricate it and a visual inspection didn't show up any obvious issues such as broken tracks or joints.
This is the detail of the microphone amplifier section from the schematic. Using a meter I have checked the continuity of tracks and have checked all the resistors for shorts or open circuits and they all read the correct values. The capacitors all look okay and checking the signals either side of C3 the C7 coupling capacitors show they are functioning correctly. This left Q1 a 2SC2240(GR) transistor as the likely culprit and I have ordered a replacement which should arrive in the next few days. I am hoping this will make it spring back to life.

TRANSMITTER CIRCUITLooking at the block diagram of the carrier unit and the above functional description in the service manual I suspected the microphone amplifier Q1 to be faulty.
The microphone signal is amplified with the microphone amplifier Q1 (2SC2240(GR)), which is commonly used for both SSB and FM transmission modes and is incorporated in the carrier unit (X50-1720-XX). The amplified signal is then fed to both the SSB and FM circuits.

I’ll admit, I fell for it!
Back in 2000, I applied for and received W2LJ as a vanity call. I had upgraded to Amateur Extra back in 1994, and I had been wanting a shorter call sign. I picked W2LJ as L & J are my first two initials. The fee was all of $10 back then, if I remember correctly. It seemed like a bargain - a buck a year.

ARLB016 New Amateur Radio Vanity Call Sign Fee Set at $21.40
The FCC has adjusted very slightly downward - to $21.40 - its proposed Amateur Service vanity call sign regulatory fee for Fiscal Year 2014. In a June Notice of Proposed Rule Making (NPRM), the Commission said it was planning to hike the current $16.10 vanity fee to $21.60 for the 10-year license term. The FCC released a Report and Order and Further Notice of Proposed Rulemaking (R&O) in the proceeding on August 29, in which it recalculated the fee to $21.40 for the 10-year license term. The $5.30 increase still represents the largest vanity fee hike in many years.
The new $21.40 fee does not go into effect until 30 days after the R&O is published in The Federal Register.
In the R&O, the FCC said it considered eliminating the regulatory fee for Amateur Radio vanity call sign applications but decided not to do so "at this time," because it lacks "adequate support to determine whether the cost of recovery and burden on small entities outweighs the collected revenue; or whether eliminating the fee would adversely affect the licensing process." The Commission said it would reevaluate this issue in the future to determine if it should eliminate other fee categories.
The FCC's Wireless Telecommunications Bureau sets the vanity call sign regulatory fee using projections of new applications and renewals, taking into consideration existing Commission licensee databases, such as the Universal Licensing System (ULS) database.
The FCC reported there were 11,500 "payment units" in FY 2014. The Commission said the vanity program generated an estimated $230,230 in FY 2013 revenue, and it estimated that it would collect nearly $246,100 in FY 2014.
The vanity call sign regulatory fee is payable when applying for a new vanity call sign or when renewing a vanity call sign, although some older vanity call signs are not subject to the regulatory fee.
NNNN
/EX
I wonder what the fee will be in 2020 when it's time for me to renew again! I think it was around $14 in 2010 when I last renewed. Oh well, if you want to dance, you have to pay the piper, I guess.
I love this part, though. "In the R&O, the FCC said it considered eliminating the regulatory fee for Amateur Radio vanity call sign applications, but decided not to do so "at this time," because it lacks "adequate support to determine whether the cost of recovery and burden on small entities outweighs the collected revenue; or whether eliminating the fee would adversely affect the licensing process." Translation - "Naaah! We decided to raise it by $5.30 instead."
Ya just gotta love the Federal Government!

Logging and datamodes with PZTLog
Organisation isn’t one of my strengths and my logging of contacts has been pretty woeful. It consisted of a spiral bound note book full of various scrawls sometimes tabulated for contests but more often than not a free form mess. With good intentions I purchased a proper RSGB Deluxe log book months ago but that has remained pristine and has just become a handy band-plan look-up!
Until recently I had only made a small number of voice QSOs on HF and had entered those manually into the online eQSL, QRZ and HRDlog logbooks I maintain. JT65 data mode logging was handled by the JT65HF program itself and for the UKAC and other VHF contests I have been using the MINOS logging program - all in all a bit of a mishmash.
Now my operating confidence has grown I am making more contacts and so I really need to computerise and centralise my logging. After looking at a number of programs I opted to give Charlie Davy’s (M0PZT) freeware PZTLog a try and after using it for a couple of weeks I am very impressed.
The program has a multitude of features but at the moment I am using it to simply enter and log details of contacts, combined with the CAT interface to the FT857-D and the OMNIRIG control the mode, frequency, band and power settings are automatically populated.
The really nice selling point for me was the inbuilt data mode operation. I have tried PSK and RTTY before using other programs but I often found myself confused and intimidated by the interfaces and jargon.
PZTLog uses the MMVari engine to operate PSK/RTTY and it uses a familiar waterfall display. The TX/RX window and QSO macros are easily accessible and I found the interface much more intuitive than other programs I have used. On installation, the macros are already populated and labelled sensibly and are easily editable. By double-clicking received text you can set Callsign, Locator, RST/Serial, Name/QTH quickly and with ease.
In a short time I have made a good number of PSK QSOs as well as a some RTTY contacts, even giving some points away in the fast paced SCC RTTY contest last weekend.
Importing and exporting of logs is very easy and it has inbuilt eQSL uploading, but at the moment I am having trouble making that work reliably but that I think is me rather than the program.
PSK is a great mode, running no more than 30W, often less I have made a number of nice DX contacts and countries including Argentina, Oman, Japan and the Dominican Republic.
Thanks to Charlie’s program I now have a better understanding of how the mode and QSO works so may try some of the more sophisticated programs, or I may just stick with PZTLog for a while. Check out Charlie's page for lots more interesting information as well as some very funny light hearted audio features poking fun at the hobby.
In other news the VHF UKAC contesting is improving. Last week I made a last minute decision to lower the pole and put up my homemade wooden 6m MOXON but glad I did. Conditions weren’t good but still made a respectable number of contacts but not a lot of distance. I’ve climbed to 30th place in the 50MHz low power AL section.

— Andrew Garratt (@nerdsville) August 26, 2014 Last night was the 144MHz UKAC and what a great night it was, conditions were brilliant and it was very busy on the band. Still operating search and pounce mode I snagged just 32 contacts, but with 13 multipliers giving me by best score so far on that band. Operating in the low power AL section as M6GTG it is hard work getting through the pile ups but it was great fun trying.Well that was fun, great conditions and some nice DX even operating as M6GTG #ukac pic.twitter.com/KwTLXiTPDD
— Andrew Garratt (@nerdsville) September 2, 2014Finally I became a licensed ‘foundation level’ amateur a year ago this month (M6GTG), and have since become an ‘intermediate’ (2E0NRD) and have now taken the bold step of applying to take the ‘advanced’ examination next month. I say bold because I haven’t taken a course or studied for it per se but with my background and education I have covered most of the theory even if it was over 25 years ago – with a bit of serious reading, revision and dusting off of the memory banks over the next few weeks I hope to be ready!Well here goes nothing.. best get studying pic.twitter.com/FTDPqTPKSa
— Andrew Garratt (@nerdsville) August 28, 2014 HV0A
It was once again a busy Saturday. I rewarded myself with a bit of radio time in between mowing the lawn and starting dinner. I hadn't looked at the contest calendar beforehand and had no idea if the bands would be full of ravenous contesters, so I headed off to the relative quiet of the WARC bands.
Holy pileup, Batman!
There was a H U G E pileup just above 18.077 MHz. Some listening revealed that it was indeed a "holy pileup" as the quarry of the hunt was HV0A - Vatican City. And he was loud - very loud! In 36 years of Ham Radio, this was about the second or third time that I have ever heard the Vatican on the air. I have never worked them before.
But today, with them being that loud (599+), I felt I stood a chance. In case you're wondering, wonder no more. My QRP sensibilities took a backseat and I pumped up the KXPA100 to its full 100 Watt setting. How many times have I heard the Vatican? Again, only once or twice before - it's rare for them to be on the air, for me to be home at the same time, and for propagation to be so favorable. I wasn't about to let some false sense of QRP Pride get in the way of getting a rare and new country in the log.
The operator was smooth and was handling the pileup quickly and efficiently. Operating split, he was running a standard racetrack pattern. He was listening slightly higher up after each QSO until he reached a certain frequency and then began listening down unilt he reached a frequency about 1 kHz above where he was transmitting. The he began listening up again, starting the whole cycle over again. Almost exacty like trying to work any of the ARRL Centennial stations - once I figured out his pattern and approximately how much higher he moved after each QSO, I made my plan to "get in his way". After about 6 or 7 attempts, I got in the log. If I ever hear the Vatican this loud again, then next time will be a QRP attempt, this time I'm just fat, dumb and happy.
According to the CW Ops e-mail reflector, the operator was Robert S53R, CW Op #492. Whomever, he was, he was good!
This is one QSL card that will be framed and hung on the shack wall, once I receive it.
Still stoked!
