You might try wading through this link at Mouser. If you have the patience to configure all the many possible filters to search for a 16 mm x 5/8 x 6-32 female thread I’ll bet you will find what you

Likewise in regards getting a couple for spares. There must have been a process or vendor problem to explain the toasted dials. I've only ever seen it on the B . John [email protected]>

I have one that is also toasted, so not much use. We need someone here who is skilful with transferring images to other media (plastic) to create some new dials. I would gladly buy a couple to have

Just an FYI the ebay seller "sell my stuff now" never shipped or responded to my November LED module purchase for the TR7 replacement frequency readout LEDs.? Ebay just refunded my purchase but I

I'd get one made out of Lexan, Teflon, nylon, etc. from eBay.

The ceramic insulator is 5/8 in. 16mm tall, threaded each end. ?Diameter could vary. Surplus sales does not list one that length. Just 3/4 in. ?The break seems to be old and parts of the ceramic

My R4B has a "toasted" dial. I've seen them turn out this way when it's left in the sun, but usually only that section that is exposed. This one seems darkened throughout. Anyone have an extra for

Hi Bob.? Yes, I discovered that early on.? At 20 meters and above, however, peaking the preselector didn't solve the problem.? While I had carefully aligned the R4C using the Drake recommended

This radio SOLD. - Alan K9MBQ

I would be happy to share it.? It's always a work in progress, but let me clean it up a bit. John WB0RXL

Hi Guys. I installed the aforementioned freq counters for displays on both a n T-4XC and an R-4C probably 10 years ago. At the risk of pointing out the obvious, you have to re-peak the pre-selector

Thanks for your input, Jan

Thank you Stan, I have some of those in the junk box. Looking at the manual, the removal looks challenging. Mike G3ZCC

This reminds me of a frequency counter I built in high school. It was a simpler age. Lots of 7490 decade counters. My counter was extremely insensitive. I tried to get it more sensitive by biasing

If the pushbutton for the PBT is REALLY dirty, you would get something like what you see. Try a bit of contact cleaner on the PBT button and exercise it a few dozen cycles. Gary W0DVN

As already mentioned, that suggests that the fixed passband pots are not doing their job. You may be losing voltage somewhere. The service manual does a very good job of explaining how everything

I used 1N4007 to replace the pin diodes in the TR7 I have. They work fine. 73 Stan KM4HQE

Jim- I think you're on to something. I have carrier that persists after I open the key on CW, and I have carrier being transmitted on SSB. Only a couple of watts of output, sounds awful. The "BFO"
