You really don't have to paint the holes... Barry - N4BUQ

An alternate way of getting a Drake transceiver with nice audio response is to use a TR-3. Those old 4-pole filters have a more gradual slope in their passbands. Of course, you give up sidetone on CW

Stan, be sure to see the article on Ron's site about getting the textured finish. It's fairly easy to do but takes a little finesse. You basically use satin black spray paint and drill a small hole in

Last week I had contacted Frank?WB2UJS at Noble over email.? He said that he does not may any filters or?accessories for the TR4's.? His advice was to find someone selling off one as parts from an

The good thing about painting the PS/Speaker cabinet, is that you don't have to deal with the 95,392 holes punched in it that are found in the other cabinets! John K5MO [email protected]>

Jim, Sometime when you get a chance I would love to see pictures of your spark gaps. 73 -Jim NU0C "Jim VE7RF" <jim.thom@...> wrote:

Hi Sean, About 5 years or so ago, I acquired a TR-4C and did the very same thing with it replacing the original filters with the INRAD #1901 & #1902 filters! While I also get pretty good audio reports

I've made some progress on the AC-4, MS-4, T-4X and R-4B projects. I installed the Heathkit Shop upgrade kit in the AC-4.? New speaker in the MS-4. Today was a nice day in 4 land, so I sanded the

I found one of those at a hamfest. Unfortunately, the inside was completely trashed, as was the meter movement, and I tossed it. I did get a nice leather case out of the deal. Steve Wedge, W1ES/4 Time

I have a TR-4Cw w/rit with the #1901 and #1902 filters, bringing the SSB bandwidth to 2.5KHz (vs the 2.1KHz stock). Also have a TR-4Cw (w/o rit) with stock SSB filters. I get *much better transmit

The Drake MN7 I intend to sell along with some other peripherals is in bad need of a paint job. Not necessarily scratched up but just worn and faded.

Update, I purchased the knob from: https://mgs4u.com/product-category/rf-components/surplus-components/knobs/ As recommended by w9gb. Thank you Sir! 73 Bill W4WCS

*** I've got one of those. Hiding in the junk somewhere. Scored it at the ham swap for a whopping $10. INOP. I cleaned up the connectors, replaced the multitude of batteries - still INOP. The

I have a TO-6 and it’s a great cap tester! It will give you quantitative results for leakage and can measure insulation resistance on non-electrolytics as well. Steve Wedge, W1ES/4 Time flies like

No that is NOT normal. Rob, NC0B

I don't think its "normal" for any radio. Lets see what others with this set have to say. Sounds to me like something heat sensitive. Maybe even a bad solder joint. Since it starts when the set is

Just had my R4A restored by WB4HFN and it gives you S9 to 20 over static when you first turn it on. ?It lasts for about one to two minutes and then goes away. ?I think this is normal for these

*** This high impedance stuff can be confusing. My KWM-2 had a thing where it would take a second or two to switch from transmit to receive. Turned out to be a leaky capacitor in the very high

It will be really interesting to see the plate current comparison. Gary W0DVN

That is correct.? Eimac almost no orange with same drive and output as the RFP I had to put it aside for bench space for more pressing matters. I'll try to fill in all the blanks next week Paul
