Good Morning Jeff, mate just to advise the TS 940S power supply upgrade arrived safely, and packaged perfectly. Great work by you and your company.
Ok, installation was a breeze, followed your information via the online Compudigital video’s, thanks for that, a great initiative. Initial testing confirmed all voltages were set perfectly, but I did have 1 issue that I had me scratching my head and wondering if the radio had suffered some damage after the existing supply had expired,,,,,, when powered up after the conversion was done, the radio clock display was oscillating at 1 second intervals changing from displayed time to displayed ATU ready, really weird, also Audio was dropping out in tempo with the display change.
After some thought, I remembered that while I had the radio on the bench, preparing for the delivery of the upgrade, I replaced the clock battery, then I remembered reading about the reset switch, behind the clock, any way carefully lowered the front panel, and hit the reset, bingo oscillation stopped, thank God.
Once radio was tested and all functions operating, it was time to have a go at the PLL unlock, and replace the second battery at the same time.
Got the PLL board out, and discovered the foam block, removed the block, got to work on the bottom of the board where the foam block had attached itself to the tracks, spent 2 hours removing the garbage from the traces, re soldering dodgy soldering, and upon completion, the radio now initiates from switch on with the PLL unlock now history.
Well done to your company on giving us all an opportunity to “resurrect” these radios.
I have two 930SAT’s that I will be changing out the old supply’s as well. I hate the feeling of trepidation every time I switch on or off these radios, the Upgrades will let me enjoy usage of these great radios once again.
Kind Regards,
Jamie Frencham.
