Radio receives, won't transmit - why?
 

Hi,
I have a Uniden PRO510XL hooked to a Firestik II FS 3ft (maybe it's
4ft, I don't remember), which is hood mounted on a S-10 P/U. SWR
reading is less than 2 ( I can re-measure and get exact #s if wanted).
I have clear reception (based on listening on the highway, I assume a
few miles), but I have no transmit capability. To confirm, I went over
to a friends who has a CB in his car and we tried talking to each other
with our vehicles a few feet apart. If we turned down the squelch on
his radio so there was noise and then keyed my mic and spoke, his radio
went silent but no voice went through. I tried swapping mics with him
(since I could receive him no problem), with the same result. Can
someone provide some guidedance on troubleshooting some more? I know
this radio worked in the past, but it was with a different antenna
setup. Since the SWR is okay, does that imply the the antenna setup and
the radio transmit is okay and the problem is with the mic - transmit?

Oops, it's a PRO520XL, not 510.

Radio receives, won't transmit - why?
 

When you transmitted and your friend's radio went silent, you were indeed
transmitting, only there was no modulation of the signal. You were
transmitting a pure carrier, and that is why his radio went silent. (power
was going out, but no voice was imposed on it).

Something in the audio path from microphone to the transmit section is not
working. Once upon a time, many years ago, I had a radio that had a PA
switch, which allowed putting a speaker on the car and using it for public
address. Unfortunately, it also transmitted a carrier whenever using it
as a PA, but hardly anyone noticed because it was at so low a level.
Perhaps if your radio has a similar function, that is your problem.

If not, you probably need someone to look at the audio chain through to the
transmit section. As many relatively inexpensive rigs use the same audio
chain for transmit and receive, it's possible that the problem is either in
switching or the microphone preamp circuit....

Good Luck!

Most likely... your microphone cable needs attention.

Also, unless you can do the repair yourself, not bring it to a repair shop.
That is a los cost CB. You can buy a new one instead.

Mine did the same thing, it worked great - then one day out of the blue, it
stopped working. It's a cheap radio, not worth the cost/time of repair.
I havn't bought a Uniden radio since. If you buy another uniden,
don't get anything less than 68 or you'll be sorry.

That ancient Galaxy? That was actually for a ham friend. I was acting like it
was for me, because I would have purchased it for him. He didn't have internet
access or ebay account, or something like that. He ended up getting Ameritron
AL-80A. Seems this is a good amp. But I know little about HF ham amps. So I
inquired about it.

Well, mine is the same as the Grant XL/Cobra148 Phillippine version. So far so
good. Great receive. Mind you, mine was new and not hacked. The only thing I
have done to it was unluck the clarifier. No other mods.

Don't know anything about it. The reason I had inquired about that Galaxy, was
because the solid state amps were in the neighborhood of $1,000-3,000. So when I
inquired about the Galaxy, it was about $200. It took off from there. Luckily,
many hams came posted to stay away from that amp. They said there were cheaper
alternatives that were better.

I think that Ameriton was a single tube radio. Highly recommended by hams.

As far as the Dentron, I use this site on eham:


http://www.eham.net/reviews/detail/1609

There are Hams indivdual reviews, and I find very useful.

Yea that's a good review sight I've read up on a few things on there over
the years. I'm not in the market, still have the 30 L1 that I hardly use
much anymore. I also have a kenrich 515 that I think is a similar
configuration to that galaxy you were speaking of. It's been mothballed for
years along with the browning mark IV, it has the veneer on it to resemble
the browning.

Yeah, alot of the hams really pushed me away from that Galaxy amp. And it was a
Ham amp, since it covered 10-80.

That is why I posted that site. Seems the bad rep comes from a recall that many
radios were never sent in for. The only thing was they didn't list the recall
problem.

I'm running a Taiwan made 148. I've done my own mods to it over the years.
clarifier, channels, tuning. And just to **** Dogie off, I'll mention it has
an echo board from an old connex. It's ugly, faceplate is worn and some of
the LEDs are dead on the channel selector. I still get good reports on it.

Maybe the front is different, but the insides look like the scrapped
