Next radio is a connex 3300HP Radio has no tx and rx. There is audio in the speaker but no rf what so ever on a watt meter. There is also no reading on frequency counter. Like the pll is out of lock nothing and of course someone was in to the radio can tell the vco and other cans moved. So...

So i was able to fix the radio 100% and the echo board is working also. What i did was follow the schematic center out of the mic gain in front and feed the echo board and now radio has audio and echo with all functions. Something in the front face plate most likely a broken trace/wire. On to...

Im sure you are correct I think its the dimmer switch and the shrink tube is one with glue in side so Im going to let it stay. I was able to get the audio work by bypassing the echo board. On the schematic without echo board the center of the mic pot feeds resistor 202. So I jumped that and no...

Well i just did a bit more checking and audio is getting to the mic gain pot and back out to the Echo bd. With audio trace good clean audio and if I put the echo on that works also. Getting audio at all 3 red arrow locations Not getting any audio in the the rf signal power out. dont know what...

Just thinking that it might not be Q53 or 55 because im not getting audio to the in of the IC7 BA4558 mic audio chip. I would like to try to bypass the echo board but no schematic on how its wired in.

Well I did some detective work and no good results. I checked the mic input and good audio. I went over to the IC7 BA4558 and no mic audio to the in on both channels and of course no output. I checked the mic audio right in the front panel and a few components but looks like the front panel will...

Superlid Thanks I see that in the block diagram will check ic 7 out and then the 4 trannys. So this radio uses a separate chip for receive audio then a chip ic 7 for the mic audio. Older radios always used 1 chip to control both. Thanks again will check tomorrow.

I have a Galaxy DX929 AM radio. There is good receive Audio and good tx and rx. There is no mic audio and no pa audio. If i key radio about 3 watts and turn on a radio next to i can not hear any audio when I keyup. If i turn on the echo and then key up I can just faintly hear the mic audio...

https://www.amazon.com/gp/product/B0C19G7HVW/?tag=worradfor-20 This is what I bought should be here Saturday some time

I watched that exact video last night and hope its not fake as I will just call Amazon for a return and what they will do is refund my money and tell me to keep the Item. Paid $18.00 with Prime shipping for 6 tubes/syringes

Yes I did read about it and if the color is dark its counterfeit. I think the real deal should be almost clear in color. I watched a video on Youtube last night

I ordered some off Amazon thanks for the info.

Anyone out here doing surface mount soldering. If so what are you using for flux. Im looking for a good Gel flux not the rosen core flux liquid. I see on ebay in syringes but was looking to get in a bottle. So if you are using a Gel flux what name brand. thanks for any help.
