The only voltages that are close are the driver and final, the rest are off, not even close. Makes no sense. You dont think #7 dead pin on ic3 is an issue?

Ok, thanks, i had it right pin @4.77v. Looked more like a 1S to me. D14 and R62 have about the same voltage 2.?v ide have to check again. Edit When key up the green rx light will turn red to indicate tx.

I checked pin 15 (i believe i have the right one) and it shows 4.77v, is that considered low?

Checked voltages on IC3 all good except pin 7, its dead. Followed trace back and it shows the 2v is being supplied to it.

Checked most of the voltages, nothing really matches the list.

Thank you Andy. Tweaking L21 made no difference, The radio had no tx when i got it. When un-key i can hear a pop sound from the speaker. I will re check the solder side again, maybe i missed something.

Yes ive saved those pics for future references, thank you. I checked voltage at R70, voltage on both sides. RX 7.82v on the inside 7.91v on outside facing side of radio TX 7.49v on the inside 7.88v on outside facing side of radio

Ok, making small steps with progress, had a echo board and variable power mod with wires going all over the place, removed both of them to start with a clean slate. Ive got the no rx after tx problem fixed, a tweak of L22 brought it back. Now to work on to why no tx, no carrier no nothing will...

Thank you Andy, ill check that out and report back with any progress.

Replaced TR21, no change, rx will stop working, speaker volume drops to about half to what the volume control is set to.

Apon more investigating i dont believe its the filter. If i key up for a second it loses receive, if i shut the radio off then back on receive is working again. Edit Replaced c117 no change. TR21 has 7.6v on collector when keyed, 39mv unkeyed.

I do have an old uniden pc 77, would that filter work? Found one on the web but they want close to 35 bucks by the time its ships and sales tax, thats 25 bucks more than what i paid for the radio. o_O

Any info on where i could find 1 of these? No success using the cobra parts list number. Receive drops out after transmit (which is not working either, may need a bit of help with it later) and if i tap on it rx will come back, its also has some wobble to it, i suspect the pins are corroded...

Belgium, Germany on 38, band is starting to open up.

I also just talked to 404 from miami beach, was his second contact of the day.

Called out a couple times, not looking to good today.

Ive had the tornado up for about 4 years, tunes easy, no issues, hears great and low noise. Its been through a bunch of 80 mph winds and nasty storms and it has held up just fine. it will handle a bit more power than its rated for. Great antenna for the money, no down sides to it that ive come...

So ive been on the AM side for a few days with the cobra 29, 95% of the stations i hear i cant understand a word they are saying, im not quick witted enough to make everything rhyme, i dont pick cotton, i dont like repeating myself, i think they are warning me there are bumps in the road, if i...

Repaired it with piece of solder braid, it was the same width as the trace, it came out ok. tested/replaced the protection diode and radio is now working fine. Did the alignment per cbtricks info, made a world of difference on the rx side and just a tad more tx watts. Pairs up nicely with my ts...

Working on a cobra 29LTD Classic, (mfg1996) received it DOA, no mods done to it, factory stock, doesnt power on. Checked protection diode and it shows continuity on the 2 leads, should not be that way correct? (diode location in pic at arrows) also as you can see there is a burnt trace just...
