John, theres a good chance there is nothing wrong with the counter. You didnt say if the rig transmits or receives. Does it? Youre missing the input from either the PTO or the osc/mixer. I cant recal
hummm. Im going to shoot from the hip here. I dont believe you have a PA problem. I suspect its a logic board failure. The CPU instructs many of the circuits on what to do and when to do it. The Omni
Guys, Ive designed a small circuit that will run the a dc fan at high speed for a dozen seconds then drop the speed down to as low as it will run. That way, the fan is sure to start, no matter how mu
The lm317 drives the fan(s) so up to the current rating of the 317 or about an amp. Most small box (muffin) fans draw considerably less current. The idea is to get the fan up to speed, then slow it d

Thanks, Steve, I guess what they say is so true, there is no such thing as a free lunch. The pcb house I use could make those for about $5-8 a copy (100 pc lots) if they have the gerber 247 files (in
Jerry, if you can get the file converted to gerber files, Id spend the extra money and have them cut. and if you can get them converted, Ill make a few prototypes before a run is made. Mike, WB8VGE S
Iam surprised no one mentioned this before Unplug the two wire plug ( that is the output from the microprocessor near q3) on the 81246 logic board. Problem solved! Mike wb8vge Sent from my iPhone
I guess it was a year ago I put in a DDS replacement for the PTO. Rock solid. Dual VFOs, speed sensitive tuning, all kinds of goodies. I took it out and the analog PTO back in. Yep, it didnt have the
Oh thats a hoot! Last fall, I had an old Drake TR-3 on the air. Those three 12JB6s were screaming, plopping out almost 200 watts into the antenna. Long story short. I answered a guys CQ on 40 SSB. We
