Well, I went ahead and replaced that 330uf cap someone had placed in the C92 location, with the schematics value of 47uf. I noticed a slight change in the tone on receive, more natural sounding, and my locals said the tone of my transmit isn't as bassy as before, more natural sounding also...

Got an old classic Cobra 142 GTL on the desk. Issue: Transmit low in all modes Receive low in all modes Controls/switches scratchy Variable key not functioning correctly Decided to do a complete recap first. Upon removing the old caps, I noticed the C92 location had a 330uf 16v cap instead of...

My PEP meter shows 50w max swing. My Peak meter shows 35w max swing. Neither meter has ever been opened. I bought them both brand new myself. My oscope corresponds very close to my Peak meter, after converting from AC volts to watts. I've never seen any other old president on my desk doing 50w...

Got an old school two button President Washington (upd858 PLL), with an old school 1306 driver and an old school 1307 final on the desk. Issue: Blows fuses once turned on. Cause: All caps, every single cap was shot. Fix: Recapped entire radio, even power supply and button board. After fixing...

Came factory with a 10khz switch. I'll check PLL voltages and get back with y'all. Seriously though, this is strange to me, lol...

Got a Galaxy DX 2517 (mosfet version) on the desk. One of my previous works. Issue: Owner claims the frequency counter would switch through frequencies all by itself while just receiving. Did not affect the actual receive or transmit frequency, radio still received and transmitted on right...

Well, I noticed after talking on it for a bit that the carrier was fluctuating slightly. So I reset the keys to 8w to 40w as per someone else's recommendation. So far, holds at 40w the entire time of talking, sled amp gets slightly hot after 20 minutes of long winded talking, cools back down...

Well, I had to put the 10k ohm resistor back across the AMC limiter. Without the resistor, the radio makes a terrible buzz sound with your audio when keyed up at any carrier level which peaks out the output. With the resistor, the buzz sound goes away and audio sounds great. Any advice on...

Got a Connex CX-4600 Turbo on the desk today for just a checkup after 4 years of being stored. After warming up for 30 minutes: Hi deadkey = 75w, WOW!!! Lo deadkey = 25w, WOW!!! PEP swing at any deadkey level = 225w Peak swing """"" = 165w Average swing """""" = 92w Found a diode alone...

Just got finished working on an old Galaxy Saturn (ept3600 board) that had some receive issues. AM receive was ok, not the best in the world. AM meter had to be cranked almost wide open. SSB receive was weak, it was there but volume had to be turned up halfway just to hear people. SSB meter...

Just posting on my review of the new RCI-29 base radio. Two of my local friends joined together and bought 2 of the RCI-29 bases from Anderson Radio Supply located in SC. They had to place a pre-order about 3 weeks ago for the radios. Well, the radios finally arrived at their homes. One guy...

8.56v

Got a Connex CX-3300HP on the desk today with low VCO voltage. Cannot get the VCO voltage up to 3.20v. it'll go up to 2.19v and then drop out or start dropping back down. Issue with radio is, frequencies are all out of whack. 10.2398mhz measured on pin 4 of the PLL. 15.23??mhz measured at TP3...

Not sure, but I will check. Picking it back up this weekend to go over it to find the issue.

Yes, he tested his jumpers and they were fine, he used new ones anyway, same result. C199 maybe? I think there is mention of the galaxy 44v aquirring an oscillation on transmit audio which turns out to be C199. It's on the archived version of cbtricks under galaxy symptoms and cures. Not...
