Hi Mark, Yes it is a happy ending! Regards the 1296 board, it is one made by my ham colleague from a design by Bertrand Zauhar, VE2ZAZ. It places 8V on pin 3 of the PA which makes it more linear than the 6 or so volts that pin 3 of the PA was getting from its pad. I will send you more info directly. 73 Starr ZL3CU

Hi Starr,
What a happy ending to your story! :)
Can you please explain what you mean by the "board" installed in the 1296 section? What board was installed?
Thanks,
Mark N8MH

Hello All, First of all many thanks for the help from Mark, Matt, and Henk. This bulletin board is certainly a great resource! Update: Today I took my TS-2000X around to another hams place and he fitted a board similar to the one he fitted in his radio in the 1296MHz section . The radio is now producing very good quality SSB :-) After we installed a 70cm and a 23cm antennas on his tower, we decided to take a look at the PLL/VCO PCB board in my radio. There was no noticeable long component leads or soldering that needed attention so it was replaced unmodified. Taking Henks advice I, where possible, rerouted all the internal coaxes on the board and the boards adjacent to it so that the coaxes passed between the components differently. Of interest one coax did a semicircle as it went through an opening near the front of the radio of a PCB compartment and then went into the other PCB compartment via its similar opening. This semicircle had a ribbon cable going through the middle of it. There was a spare grove between the two PCB compartments for a coax to go, so I placed this coax in the grove. The radio was then assembled and tested. HEY PRESTO the problem was GONE :-) . I have done this fix a only few hours ago now and so far the problem has not returned..... Fingers crossed!! Henk, looks as if your fix has worked for me too!!! Full marks. If it did not work I would have done as Mark suggested and do an firmware update next. (I have the bdEF version which initially caused me issues while I tried to load it into the radio). Best wishes to everyone on the bulletin board. 73 Starr ZL3CU

Hello Starr,
I think the update for the PL tones was *after* the update for the CAT control while transmitting. So, you probably already have that patch, and it might be the PLL afterall.
Nonetheless, I would try a firmware update and a full reset of the radio before send working on it or sending it back for service.
Best wishes for a quick fix!

Hi Mark, Thank you for your email. I did update the firmware a few years ago and the update did include the PL tone fix for satellites. However I will see if there is a later version and keep you informed. Thanks again. 73 Starr ZL3CU

Hello Starr,
Perhaps you can first try an update to the radio firmware. There was an early fix specifically for issues when the PC updates the frequencies while transmitting.

You only need to update the most current version, and it fixes all previous issues. There is a PL tone fix, too, which is important for satellite work.
I hope that fixes your problem! Please let us know.
