Rick,?
You might try setting it upside down on an electric hot plate or stove burner.?

Well...I have a small metal Vise out in my garage.
With that and my 100W soldering iron, it should be a piece of cake, Thanks.

If the knob isn¡¯t split, try tapping for a larger setscrew.?

The shaft does have a flat spot on it and there is a bushing inside the

Unfortunately the set screw hole does seem to be stripped and will not

Attached is a picture of my knob and switch. It is not as rusty as the other picture.

I cannot tune in the SSB signals, the mode control just spins around and has no effect.
This is the first time I have tried to listen to SSB so this is new to me.
Looking at the schematic before I open it up it looks like the mode switch should have a few positions to it and not just spin around.
Am I correct?
Thanks much,

I was enjoying some casual time with putting my Collins receiver back together and decided to try getting the crystals better looking than the greenish-brown that they were. I¡¯ve seen Drake crystals that sometimes look this bad and decided to try an old standby: Bar Keeper¡¯s Friend.?
It took very little effort to make these crystals look like they did in 1964.?
Bonus: BKF seems to help with old, dull knobs, too. I¡¯ve been using a handi-wipe but could see getting this loaded into a Dremel buffing pad.?

Put the leads in a Panavise with heat-resistant jaws and the can should come off with a little heat and a grab with needle-nose pliers.?

Re: Drake 2C on 28.0 to 28.5 MHz

What I was thinking was to cut the top of a HC-6 off and solder a 24.5 Mhz HC-49 to its pins.
Don't know if that is doable tho'

Re: Drake 2C on 28.0 to 28.5 MHz
Well that didn't work, so I copied and pasted my older post.?
Thanks for the responses regarding my crystal needs. One of the links led to a company that had the 24.5mhz in an hc-6 can but it was priced at $30.00 + shipping + tax. That made it a $40.00 xtal!
I found another way that was super cheap and is actually a better solution.?
A while ago when I was restoring my Drake 4a, I ran into the same issues looking for extra band xtals, so what I did was to purchase xtals in hc-49 cans which had leads. I then cut some sections od PC board pads previously purchased from QRPME. Using an hc-6 xtal as a pattern, I drilled holes, cut pins from rods purchased from Ace Hardware, soldered the pins to to the PC board, and then soldered the crystal to the pins. After I checked them out in the receiver I potted them in 5 minute epoxy.?
Now to the Drake 2C. I remembered that I made a 16 mhz xtal for the Drake 4a, and figured that one of the harmonics would be 32 mhz. Subtract 4 mhz, and you are at 28 mhz which is the bottom of the 10 meter band. I plugged it in, switched the 2C to 10 meters using the xtal calibrator, peaked the preselector at just below full clockwise, and it worked!? The best part is it now tunes up using the main black tuning scale instead of backwards using the red scale.?
I checked everything out running my Ten Tec Argonaut V into a dummy load while listening on the Drake 2C.
These hc-49 crystals are dirt cheap costing about $1.00 each from the many electronics suppliers, and even cheaper from Aliexpress. If you make a few band crystals, by the time you are done, it will probably cost you about 2-3 bucks each.?
I plan on buying some more to cover other bands.?
I hope this helps others.

Re: Drake 2C on 28.0 to 28.5 MHz
I used an hc-29 16-mhz xtal and a home made holder. 16 x 2 = 32 minus 4 gives you 28 mhz. Works well. Cheap too.
Here is a link to how I did it in a previous post,.?

Looking for a Drake R8B in excellent or better condition and no smoke exposure. The VHF module is highly desired, but not a deal breaker if the radio doesn¡¯t have it.
I am good on QRZ. Thank, Lynn ku7s

Dave,
Ok, I got figured out how to package it so it should get to you with no damage.
Its too late today so I will take it to the post office on Monday.

Re: TR7 Extender Boards for sale. And a bad DR7 board, maybe.
Bill, do you know the nature of the problem(s) with the DR7? If the counter/frequency display section is not functioning but the "All Band Coverage" with the push button Up/Down controls does work, I would be interested. To contact off list, my email is good in qrz.com.

Green is usually glass-epoxy, which is a better substrate.
