You are correct. L127 is the one for USB & it's dead. Thanks.

Thanks. I check those pots to see if there working.

Hey: Gang. I'm working on a Magnum Delta Force 10 meter radio. It works perfect on all modes except USB. No tx or rx on USB. I did some internet searching & seen that I should check crystal x103 & I did & there was a lots or rot from that nasty brown glue so I cleaned the board & replaced the...

Hey:. Update for you, I starting using MJE2955T regulators to replace the 2SA1012 that blows in those radio. You can use a NTE153 also but the MJE2955T is a higher current device & will never blow like the original. You can order all the parts I mentioned online. Where are you located ? I'm in...

Hey: Gang. Had a buddy brought me an old Courier Centurion 40D. It transmits on AM but not on SSB. No tx on SSB is due to not transmit audio. I have not recapped the entire radio yet but I did replace all the electrolytic caps in the audio section & replaced the audio chip as it was pitch...

I agree 100%. There are plenty of other Presidents names that could have been used as we all know the Washington as a base station. How about President, Regan, Nixon, Ford, Bush.

Hey: Gang. I'm working on a Magnum S9 with dual 2SC1969's. It had very low tx power & no tx or rx on AM mode only so I replaced the 2SC2166 driver & both finals which fixed the low power issue. It now does about 40 FM & SSB but there is still no TX or RX at all on AM mode. FM & SSB tx & rx fine...

Google Vanco LC6X to find this cord. I've been searching too & I found them.

Got it fixed. Turns out C89 a 0.01 uf film capacitor was shorting out TR32. There was a dead shot across this transistor & when I removed C89 the short stopped. I replaced C89 with a new capacitor & the ALC now work. Thanks for all the help guys.

Hey. Gang...

Update & good news guys. It turns out I had a few bad solder joints & had to scrape off this thin plastic coating that is on the ribbon cable for the channel selector. After exposing more copper trace I got solder contact & the radio lives. :)

Hey: Gang. I'm in search of a complete ribbon cable with channel selector switch / led channel display for a Realistic TRC-458 base station. I was having issues with the channel selector being worn & not staying on channel. I tried to use contact cleaner & get it inside the switch but the...

That's awesome. I had the Super big stick 18' long. I believe the Big stick is 16' long. Great antenna though.

If you look up A99 exposed, there's a guy who took an A99 apart & there is just a copper wire in the middle & top section. The bottom section contains a capacitor, two coils & then just wire to it's top.

Ok guys. I bought 2 NIB bottom A99 sections from an electronics clearence place, there were no middle or top sections. So I decided to make my own middle & top section out of aluminum tubing. I had a broken Imax 2000 & removed all the chromed parts so I had parts to attach the middle & top...

Same power before & after all electrolytic caps, now driver & new final, plus new relay. Turns out someone had their golden screwdriver inside & mistuned the tx rf variable inductors before the pre driver stage. Got it back to 4 / 12 watts now. Thanks to everyone for their time & input.

Hey: Guys. Got it fixed. This radio looked virgin inside as all the wax was still in the pots & there were no mods but it turns out someone monkeyed with the transmit alignment pots in the section before the pre driver. Got it working correctly now. Thanks for all the help guys.

Did all listed in the tech updates, no difference. 1w on AM & 3w on SSB. :(

Hey: Gang. I'm really stuped with this Cobra 139xrl I'm working on. I recapped the entire radio including the tantalum & electrolytic capacitors. I also replaced the four 2sc1419 regulators with new ones. The radio will only put out 1 w on AM & 3 w on SSB. I replaced the 2sc1306 driver &...
