Ah ok. Makes sense now. Thought I found a goldmine. Lol

Hey gang. I have 2 sets of demco super satelites. One set has white meters and has a cable hookup which is a round 11 pin connector. Anyone have the pinouts so I can make a cable or know where I can score this cable? Also, my radio set that has the red and green meters is in need of a service...

Hey Dan! Alex here from facebook. 73s!

I never understood how a 2sc2879 could overdrive to develop anything over 100 watts. I have a 667 and all Ive ever seen on calibrated meters has been 350 watts peak and 250 rms. Measured in USB with 11 watts out from a cobra 2000, and then 20 watts from a SDR. Ive seen crazy claims about these...

Check to see if the tuning can string has slugs turned up above the top of the cans. If so, this could also be a problem.

Probably all sold by now but please correct me if Im wrong. You are/were selling 3x 1600s for one low price of 1600$?

Ok. I got a response. Apparently Barkett sold his browning stock to a fellow in IN. I sent them an email. Hopefully I will get a response back. At the very least, i need that 5.6450 to get my usb back and I can vfo the rest.

Hey all. I need a bunch of crystals for my mk3 ssb transmitter. I need the USB 5.6450, and on the dial I need ch 2,5,6,7,8,12,13,14,17 and 22. I was trying to place an order with Barkett as Ive bought from them before and got stuck on the USB and many other crystals being out of stock...

Thank you Sir. I so enjoy your posts and support in the hobby. Very awesome. Gonna place an order with Barkett Electronics soon. 73s

Got some more done today. Thanks to nomads trick, I used my SDR as a "sniffer"and tuned in on each of the 6 mode crystals. I scoped them as well. Found the bad one on the USB side. Gonna see if I can order all the ones that are bad on the dial and mode sw and get the front end back up. Still...

Worked a little on the transmitter today. Cleaned and tightened up the tube pin contacts, went through all 23 crystals, cleaned and tightened the crystal sockets. Got some headway made. I guess some of the cans need tweeking. Some of the crystals are not tuneable. Some are off as much as 5k. A...

Its an ebay find. Its not even the same transmitter as my other mk3. Its a later one with a pot on both sides of the chassis. My other one only has 1 pot and it runs well. This bad one has been canibalized for sure. I pulled out a bunch of mods that were not original and set it back mostly. It...

Today I checked all 6 mode crystals to see if I had rf. Couldnt check actual frequency probably due to not enough rf output on these crystals. Freq counter doesnt see the rf. On AM I can see mod on the scope. Nothing on ssb. Notvenough tx power out to move my wattmeter but enough to see that I...

Thank you Sir! I will try that tomorrow. Much appreciated. 73s

Mk3 ssb+am. Im searching for any post that reflects some help on a transmitter that screeches while in am and pins the needle. Ssb has not been tested yet. I pull the 6bq5 and the screeching stops. The 6bq5 works great in my other transmitter. Resistors check within tolerance. Caps All replaced...

Thanks. Thats definitely useful. Well, gotvtime to scope my oscillator circuits today. Nada. Now I know where to begin. Appreciate the support. 73s

On my txer, the mod would switch in the 5 mhz crystals for am and lsb to a slightly higher set that would add in the channels from 24 to 40 and beyond. It made channel 2 into channel 24, 3 into 25 and then skipped 26. Pick up again at 27 through 30, skip 31 pick back up at 32, skip 36, pick up...

Those coil cans are just like the ones in my midnight spevial and gemtronics 5000. Lousy slug threads. Worse is that the company that made those chassis used a horrible paint to seal them in place which made them near impossible to free up without thevrisk of breaking the tuning slug. The idea...
