[@AdamosDad]

Love the retro equipment since I am retro myself🎙73's kd9oam

[@NebukedNezzer]

I have a rare drake receiver an SW4 (no suffix). got it and matching MS-4 both in excellent condition.

Hi Mike,You really do it very nicely. I also restore such old HAM radios. Now I'm taking a break and watch you at work ;-) I'm looking forward to the next episode.73's DF7PI

[@MIKROWAVE1]

Bernd you had better get back to work before we both get in trouble! Ha.

[@BoB4jjjjs]

I love this old dangerous stuff. High voltage, high amps and all come with high hopes. Stay safe.

[@MIKROWAVE1]

Oh yes.

[@BruceNitroxpro]

You know that only someone who had that power supply in front of them AND was warned would EVER have known about that cap and screw interference! LOL GOOD for you!

[@davidedwards5461]

A great channel Mike. I liked your series on the R1155. gm4glg

[@MIKROWAVE1]

That radio was a tough nut for someone on this side of the pond.

Nice video. Bought the C Line a few years ago and still working. I have a couple of Heathkit and Swan supplies that may need refurbishing. Nice to see the big electrolytics are replaceable at a reasonable price. Nice videos Mike.

[@MIKROWAVE1]

You can spend what you want to with caps. The rebuilds are wonderful from Hayseed Hamfest. And some folks stuff their own replacements!

[@nyworker]

@@MIKROWAVE1 Thanks Mike

[@BruceNitroxpro]

@@MIKROWAVE1 , Who would "stuff" caps, anyway? IF they were replaced, they will probably need to be replaced again.

[@NebukedNezzer]

my first commercial ham receiver was a drake r4a.

[@MIKROWAVE1]

No wonder you are spoiled! Your first receiver?

[@NebukedNezzer]

@@MIKROWAVE1 I had receivers from the early 50s on. but the drake r4a was my first commercial ham receiver. the others were home brew or adapted to ham use.

[@MIKROWAVE1]

@@NebukedNezzer Very nice. I first used a Drake Station with a Henry 2K in our college setup at RIT. Boy was that an eye opener.

[@BruceNitroxpro]

@@MIKROWAVE1 , Geeze! Mine was an S-38D.

[@BruceNitroxpro]

@@MIKROWAVE1 , The Navy gave us a HUGE rig at R.P.I., and I can see the huge bottles in my mind now! AND the huge motor generator to drive it, too! About 500 lbs. of it out in the hall way. [Not the one at the ham station on the hill, which was conventional.]

[@daviddavidson1372]

Great video . Now you have to make a video on the drilling of the nozzle to spackle paint trick. Neat ...

[@BoB4jjjjs]

Yeah, how do you do that?

As of Saturday, Aug. 22, yours is the ONLY video which hasn't yet been blitzed with a SINGLE thumbs down! LOL Amazing!

[@MIKROWAVE1]

Boom!

[@BruceNitroxpro]

Not having read any other comments, I will say that I saw a lot of disc ceramic caps scattered about the power supply. What were they? If they should have been safety caps, they obviously were not the correct ones to use. I didn't see any disc cap values on the schematic. (??)

[@MIKROWAVE1]

The power line and caps. A great subject. Polarized Safety Cords. Cheater Cords. Safety Caps. Do they have Cheater Caps?

[@BruceNitroxpro]

@@MIKROWAVE1 , Well, I thought YOU might know about cheater caps, if anyone might know about them YOU would! The X-1, Y-2 caps would do in a pinch.

[@scharkalvin]

Since there looks like there is room under the chassis, I'd have cut a suitable hole in the side and installed a three prong power cord socket with a noise filter into the chassis and then plugged the power cord in rather than wiring it directly.

[@MIKROWAVE1]

Nice Idea. But that would be an interesting hole to cut! Bring rat tail file please.

[@scharkalvin]

@@MIKROWAVE1 I have an old nibbling tool from the 60's that could roughly cut it out. I'd first start with a few large drill bits (3/8-1/2"), then the nibbling tool, and finish off with a file. Another idea would be a Dremel cut-off wheel.

[@MIKROWAVE1]

@@scharkalvin They made me use a nibbler in college as a Co-op student building test boxes. Hand still hurts.

[@scharkalvin]

@@MIKROWAVE1 Yes that tool does take some hand strength to use. :-)

[@BruceNitroxpro]

@@MIKROWAVE1 , Or, buy a punch!

[@abobakrabdullah6237]

Hello... How are you I have Device icom ic718 plz give me more information about it

[@MIKROWAVE1]

The 718 is a modern entry level ham transceiver. I always like older ICOMs too, because they used generic parts. But newer rigs are not my thing!

[@BruceNitroxpro]

@@MIKROWAVE1 , I don't expect to find a treatise on SDR receiver design, but a mention of an Icom 7300 would be welcome! de KQ2E
