Hi to the group, Wanted: TR/7R7 complete extender board set. Thank you. Chuck - AA5WG Suttons Bay, Michigan 231-668-1115

I have always wanted to get a TR7 to put mobile in my 1980 Triumph TR8. 73, Jim W4UCK

I’d say that 100 kHz is definitely a time to retune. Normally, on 40, I’d re-dip every 50 kHz, including the driver tuning. 73, Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a

HI Doug, I just use my trusty (now old) iPhone 12 Mini. A new software release automatically does the "photoshop" cut out of the background automatically, I love that. It isn't always able to but the

Steve, Put in the Sherwood product detector mod and I bet it will improve a lot. It did to my R-4B which is just like your 11 tuber. The 13 tube R-4A though still has slower nicer AVC and sounds

That's a nice-looking set! I have an 11-tube set that's in that sort of shape, too. it does sound great -- even with the SS prod det. Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a

The behaviour you describe is normal for that component. The reduction drive will continue to attempt to drive the wiper, even after it has hit its hard stop. I hope you can get it back together

The procedures in the manuals call for each to be aligned without being connected to the other. That is the basic alignment and, with the correct INJ cable, should work equally from the TX or RX as

Wow, What a nice set! The R4A was my very first radio and it worked like a charm. These look pristine! ??William N1WL ????????? CallSend SMSAdd to SkypeYou'll need Skype CreditFree via
