Winter time, is when the clunkers come out. We have random clunker nights on 16 LSB in my area. Preferably 23 channel SSB radios, but some 40 CH's come on. The activity has dwindled dramatically since Covid lockdown resolved, but a few come around. In the past 2 months, I have dragged out the...

I robbed the final and heatsink, VCO, audio amp chip and crystal filter. I believe it has a bad mixer IC also. I know I stashed the heatsink somewhere and the crystal filter did nt get used and I know where it is. I'd have to come up with a VCO and audio amp chip and bottom cover. Probably not...

Same here, I like when these threads take on new life. It was fun! 73 and Merry Christmas to ALL! SuperLid

I have a 79-892 I used on 10m back in the day. It became a parts donor. I just picked it up and looked at it to see what it needs to operate again. Might not happen...I loved that radio in my car. No amp, Larsen mag mount and I could work JA's from the East Coast, during the cycle peak in the...

Oh, wait, you said 40 CH

What model? I believe the 13-892 is identical to the Hy-Gain 674B

In the photo, you can see the DDS is on 23.710. That injection freq is putting the radio on CH 38.

I am on 16 LSB several times a week, as well as 36-40 with the DDS. These 23 channel Cybernets were great radios, I don't care what some people think or say.

Your Kraco is a similar radio to the Hy-Gain V. I tried a Siltronix 90 that I modified. I got so frustrated with it, I tried the DDS. HOLY SHEEPSHIT BATMAN!!! I'm going to be working on some DDS VFO's after new years. I need to get the correct offset for various IF's. The one I used was around...

Interesting that you mention that Kraco radio. Look at what I did this past week. It works GREAT!

Pin 1= -12VDC, Pin 2=+12VDC Pins 5,6 and 7 tied together.

I was using my phone when I messaged, which is a disaster for me. You responded first, so you have first dibs. It is just something I wanted to see out of curiosity. I never had one of those in here yet. Merry Christmas

I want the HB444/25 or Comstat 25. I have 25a and b

Or Comstat 25

That's not the one I'm after. Looking for the 25 channel version.

HB-444?

1=white, 2=red, 3=blue, 4=shield

I spoke to the designer, who said it was a Troy thing, that is not going to happen.

Ground the emitter of the keying transistor, which will key the amp. Do this with NO RF input. Then measure, the DC voltage from the RF transistors bases, to ground. If there is AB bias, you should see .6-.7 volts on the bases.

The DDS VFO I ordered from Scamazon, was defective. Zero output. This has turned out to be a major PITA. Someone has to have one of the model 6 things hanging around.
