I received my new (used) Scout yesterday. After a long search, I finally found a power plug and 9A Airpax circuit breaker in my junkbox. I built a cable with the breaker and am powering it from a 963
I don't know anything about the radio, but it seems like if the BPF is causing an SWR problem then the SWR would have to be measured at some point between the TX output and the BPF (ahead of the BPF
Tnx for your answer, Wes. I meant to say "LOW PASS FILTER" (for the final amp), not BPF. The BPF is only used for the RX and it is working OK. IMO it must be this LPF circuit, and it has just 2 coils
OK, good luck! My logic was simply based on the idea that a proper SWR measurement should be made by measuring only the effects of the antenna/feedline and not anything else (such as components insid
Rick Check the barrel connectors. They route rf in and out of the module. The prongs get loose, causing the issues your having. Mike wb8vge Sent from my iPhone _______________________________________
Mike, I was thinking along those lines too. They "look" ok but it's hard to say. I was thinking about bending a burnishing tool 90 degrees (in its length), and then just polishing the pins. It's hard
Don't forget to check/clean the connectors inside the radio, too Mike wb8vge Sent from my iPhone _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists
PROGRESS! I used a very pointed needle nose pliers to scrape a bit on the LPF pins of the 40m module and immediately had full power. So, "that's" the problem. I will find a way to clean all of the mo

The radio is oscillating and not on 40M when the output drops to 2W. Thus the high SWR on a resonant antenna indicates the RF to the antenna is not near the antenna resonant frequency. I'd do some se

Geoff, Tx for the tips. I am not familiar with those products, but probably have similar. I will do my research and see if they are the same. The products I use are: - Kontakt 60 (the cleaner, probab
Bob, I was monitoring SWR externally, into a dummy load. I intend to seriously clean all module contacts as well as those within the radio. The cause of the problem was indeed the LPF. I scraped the

Actually, the Q-Tip will likely leave fibers behind. When I do a repair here I do an inspection with a 20 X inspection microscope to check soldering, card edge connectors and anything else important.
Rick, you might try unravling the Q tip to make a smaller diameter one. Another idea we used on tight relay contacts, was soak a piece of typing bond paper in the cleaning solution, and then work it
OK, you guys convinced me. I will do it. 73 - Rick, DJ0IP (Nr. Frankfurt am Main) Actually, the Q-Tip will likely leave fibers behind. When I do a repair here I do an inspection with a 20 X inspectio
Sorry Stuart, I have no idea what you are talking about. I do have some stiff paper that I can try. That may actually prove to be the best idea. Tnx. 73 - Rick, DJ0IP (Nr. Frankfurt am Main) Rick, yo
Ha, so we do have a common past. Actually we were Tektronix. We had the exclusive distributorship for Germany for over 30 years. We were treated just like TEK employees. Same training, etc. In fact I
