I remember the Drake swap net on 75 meters.? I was a new ham in the late 80s and always wanted a Drake C line. WZ8O, now W8NS, Don, put out his phone number and said he had one for sale. I called him

Gary, Dave, John, Thanks for the replies! I removed the knob this afternoon and it is in good shape. It looks like the set screw presses against a fiber like bushing that surrounds the shaft and this

No problem - it was just a suggestion since I would like to be able to check in with my Twins. I will keep looking for better band conditions in the rising sunspot cycle. - Steve? W7SJT "Always look

We tried a 20 meter net many years ago and it never worked out. Very limited check-ins.? We also had a 75m swap net and had to disband that some years ago due to lack of participation. 73's, Mark,

The performance of ceramic caps depends on the exact type of material.? npo type are very good ,? it is the "hi k" type that have problems.? Temperature compensating caps have charities similar to

In comparing early and later R4C power supply schematics, a capacitor (C201) was added going from the output of the low voltage diodes to the high end of the filament string. It is listed as 20uf

Ceramic capacitors are bottom rung devices, with differing temperature coefficients depending on type (NPO being the best for routine cooling and bypassing applications). They do not fare well at low

Hi Bill, I use Mylar capacitors. Leakage and Q, but I suppose you could try ceramic. Rob, NC0B

I don't see any mention as to what type of capacitors to use. The reason I ask is I don't know why Drake used large tubular capacitors in their design. Is there any reason ceramic capacitors can't be

Hi Rob, It is Network Sciences Date Code (?) 7905 Thanks Lionel

One caution! If the knob is loose, please do NOT overtighten the set screw. This will surely result in the knob being stripped or split. If it's loose because the shaft is hard to turn, remove the

A normal selector switch. Is your knob set screw loose? ....Dave

Hello everyone, Last summer I picked up a 2-C to go with my 2-NT. I have been using it for CW without any troubles. I tried to listen to some SSB signals tonight and I found a problem... I cannot tune

Doug, Yeah, its personal preference at this point.? Some guys figure its supposed to be Lagoon Blue so they use blue LEDs.? OOH, not for me. Warm white is what I think is best but...? I bought the

I was going to post the exact same thing. I second it... JB WELD should fix it. You probably need to make it a little thicker than the original insulator for strength. If it doesn't plug in quite as

Lionel,Possible solution FWIW: Pull the pin out of the case to the position you want it Do some careful horizontal surface scoring near the base of the pin (small file, nail file, etc.) - don't go too

Which OEM made the filter? Rob, NC0B

One of the pins is pushed back into the filter case. I can gently pull it back into position but have found no way to secure the pin from outside of the case. I have tried various cements, epoxy,

Gary, I did the same thing but I found the bright white to look the best in my 4C line. However, I was not using the same style bulb. It is convenient to use the bayonet style though as it is just a
