Folks, Is there a way to get any more adjacent signal rejection from the standard notch dial on a Drake R4C? Bill N1WL ?? ????????? CallSend SMSAdd to SkypeYou'll need Skype CreditFree via

Matt, I just picked up a Shute 444. Could you show me how you have the plug wired. My cable has 5 wires but 3 screws on the right angle plug. Dean Sent: Sunday, February 9, 2025 7:22 AM To:

Yeah, that would work! Good thinking. I've used Audacity to build two-tone and single tone test files to drive the transmitter from a media player for testing. "atlasstuff via groups.io"

All, I recently picked up a TR-4C and power supply. I rebuilt the PS and was able to get the TR-4C cleaned up and working properly. I know this is a SSB rig but also has a CW option. I have good

I have an extensive collection of parts that I’ve owned, off and on, since the 1980s (it’s a long story). In this stockpile, I have lots of resistors, including some carbon comps that go back as

Hi Jay, I have the same station here (T-4XC, R-4C, Shute 444). I get similar audio reports as well. ?The old technology is a pure joy to operate! -- 73s VE3MXG Matt Gervais

I've added a scanned version to the files section. Single sheet and resolution is good enough to be able to decipher the switch contacts. Steve G8GSQ

Jim, Thanks for the clarification. What you described (better) is what I took away from reading the Drake manual. The process was so quirky, it raised a flag in my head. Poking screwdrivers through

In the T-4XC I worked on there's a separate 3.3ohm resistor for the current metering. Thanks for the info. on resistors; early in my working life ( mil comms) it was drilled into me that carbon film

I have loads of nib,? carbon comp resistors,? I bought new, eons ago.... and they have all drifted to the high side, ( some as much as 30% on the high side).... just sitting in their original

You can find about of the same make and size and move the insides to the old enclosure. I have done this with several different pots. Steve Wedge, W1ES Time flies like an arrow. Fruit flies like a

A bit late to this thread. Drake seem to use a lot of the CTS 450 series pots. I would guess the pot in the AC4 is a CTS 450 series. You could get one of these from Mouser and swap out the wafer.

I'll try that. Thanks! -- Joe - W7BWA Custer, WA

Thanks David. Only that the holes are there and I wanted to replace it with what is there as the shaft is very short. The main thing is finding a suitable replacement and Mouser seems stumped to one.

Kinda nice how spell-checker changes “pentagrid” to “pentagram”! Gary W0DVN

Gary, try putting the original screen resistor back and swap out tubes. It sounds like someone was chasing their tail over a gassy tube. Steve Wedge, W1ES Time flies like an arrow. Fruit flies like a

On 12m this morning, I received a good SSB audio report from MN. I've had other good SSB audio reports. I'm using a Shure 444. My CW and SSB reception sound great as well.. maybe better sounding than

I am helping a fellow with his dead R-4C. I found the original problem, a puncture in one of the coax cables' insulation pressing against the 12 volt line, pulling it to ground. Fortunately, this

T-4XC Band switch waver positions? On the T-4XC I purchased, the waver band switch is in the wrong positions. crystal positions are fixed, the others may be wrong too! After tuning only a small
