TS-930S AVR board
Thanks to KA5IPF and WE0H, who answered my query on the TS-930S reflector! The oscillation was due to dried-out electrolytic capacitors on the AVR board and unhappy pass transistors on the heatsink in the back. I bought 105 C capacitors instead of the 85 C ones that Kenwood used, plus bumped the voltage rating up to 63 V instead of 50 and 35. Fortunately, I still had some leftover 2N5886’s, but I need to buy a replacement set of capacitors and pass transistors to have on hand in case the other radio fails. I haven’t tested it in contest conditions, but all signs are good that we should be ok. Maybe the NS tonight?
Have a Synton ARC (sorry about the ancient web site…we are going to fix it…sometime) meeting at 2:00 today. Everybody else in the Club is building SoftRocks. I’m bringing my IK4AUY preamp parts to start building. Need to order some PL-259’s, probably today. Yeah, and I need to finish writing my prelim exam document and presentation. So much to do. So little time.
