Baofeng Uv-5r Has Lost It's Receive

[mr_fx]

I have a Baofend UV5r and it has lost its receive. it seems to transmit just fine... but it barely recieves anything.

I have commonly leave it attached to a large outdoor antenna... I recently read that the is a FET in there that can go bad a little at a time, eventually ending in a deaf radio...

well some of you are going to say... "check the coax and antenna"

well I did, hooked up my Yaesu FT-857d and got full signal strength, on the same coax and same antenna that the Baofeng was attached to...

Any idea where this FET is?

Do a master reset on the HT then drop the programming back on

still dead as a door nail, I have an antenna hooked up to max trac in my basement and I hit a repeater full quieting

the same repeater on an out door antenna 35 feet in the air can not be heard by the boafeng

Well good thing they are only $30

I'm not even sure how that would be possible.

He also said ....

At this point, just a theory due to repairs I've had to make over the years, on just about any kind of receiver that uses an FET for the first RF stage.

One way to test that theory would be to swap it out with a fresh one, but I would be suprised if it helped. I'd be more inclined to look at capacitors than FETs.

I don't see a single FET in the entire radio.

Thaaaaaaaaaaaaaaat's it!

If there is a service manual, I doubt that it would be much good anyway. These radios are built upon IC's and once they are toast; then they are toast. Much like a cell phone with different programming . . .

Best way to fix it? Buy a new one.

Had one at the plant that stopped transmitting. toss it and order another one. We don;t call them throw-a-ways for nothing.
