Hi Steve, I have a pretty old, but original inj cable. Do the characteristics change over time? I have been aligning without the connections. thanks, gregg

I was wondering the same thing, Peter. The parts may be of some use in other applications. Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a banana. Sent with [Proton

Thousands have used the D-104 with all manner of Drake tube gear. Check to see whether or not the mic has a built-in amp, as that will be a factor in how you set it up. 73, Steve Wedge, W1ES/4 Time

Jim: You won't find that low pass filter board in an "Export" (like Canada) model. It was installed in the US models to inhibit 10m operation in a fruitless attempt by the FCC to stop CB-ers from

What was it used for...to inhibit? amplifying > 23 mhz ??

Probably thousands of hams have used this mic with this transceiver.? The other popular mic used is/was the Shure 444! Lee, w0vt

Arnie, The front end alignment portion would apply to any of the R-4 line. Rob, NC0B

I am restoring a TR-3 and have already restored the AC-3 and purchased a nice MS-4 - I also purchased a D-104 microphone at a local hamfest recently and would like to use it with the TR-3 - has anyone

Arnie, I have used this method for quite some time, with all lines, and it is definitely LOT less hassle than swamping the premixer. The tuned band circuits are pretty much identical across the

The ones at AES look identical to the ones I have seen in some of my Collins knobs. It may be time to experiment and see if they'd work with the Drake knobs that have no setscrew. Many times, those

Rob: Would the procedures set forth in that document also be applicable to a R4b / T4xc combo? Tnc es 73 de Arnie W8DU

Jim and Stan, Thank you for the puller information. Chuck

Hi Ralph, This isn’t two rigs, but one receiver and one transmitter that can be operated as separates or transceive off of either VFO. With this much gain discrepancy between 80m and 15 meters there

Yeah, The spacing on the Drake extractor seem to be a bit short.? Seems like it was designed to lift one end of the board, then finish extracting the board with the hole on the other end of the

I like PA0CMU's copy better. Easier on the fingers. :) Of course a classic PC slot cover works best for the DR7. 73 -Jim NU0C "Stan Gammons via groups.io" <buttercup11421@...>

Oops. Missed one. RIT centering also requires the Jumper Board if you have a very early Parent Board. Later boards have a bottom access hole in the Parent. "Jim Shorney via groups.io"

Here's a pic of the board extractor I have.? Seems like I got it with the extender board kit?? Or I got it when I ordered the service manual.? Too much water under the bridge. I'm not sure. 73 Stan

The only board you need for alignment is the Jumper Board for VCO and Translator alignment. In my experience the VCO and Translator rarely need alignment. They pretty much work or they don't. IIRC the
