[PCR-1000] no receive

[Dave Hancock]

Hi Chuck,

My unit was deaf on 137mhz but was receiving FM broadcasts ok. I cured the
problem by loading on a copy of a working EEPROM I got from
http://sean.wenzel.net/lists/PCR1000/0413.html. I then used TalkPCR to make
a backup of my original, renamed it and then renamed the downloaded version
so TalkPCR thought it was my backup and restored it. 

This certainly cured my problem and as long as you can make a backup of your
original you are not going to be any worse off.

Drop me a private mail if you have trouble finding any of the above on the
web and I will send you a copy.

Good Luck!
Dave

Here is what I know for sure... It's not the cable and it's not the
computer.

I have tried to tune both AM and FM broadcast stations, but I get nothing
other than speaker hiss / noise.

I've considered perhaps it's the EPROM, but I don't have a backup.

Has anyone here had the experience of having an Icom go deaf (excluding
white noise from speaker) and subsequently do an EPROM restoration and fix
the problem?

Hi there,

I don't know if you bought the unit 2nd hand, or if it is a unit that was
working and now doesn't work any more.

If the receiver was working before and you just came down one morning and it
stopped, then we have a radio that needs to go in for repair. I assume there
are no "Com Port" errors, such as might be caused by installing a PDA or
Pocket PC. I don't know what your circumstances are locally, but here I
would certainly send it to the agents. Tell them you never used anything
except their software. Might be good to check all cables are still connected
correctly. For most people, going through the EX2099 diagnostics isn't an
option.

If you bought it and it appears not to work, then (assuming you are using
iCom's software) and the inadequate instruction manual :

Assuming you're not listening to SSB/CW with the bandscope on:
0) If you have a Dell D800 or M70 laptop its probably a computer problem.
The mic input doesn't connect to the speaker or headphones by design. There
is no "line-in".  goto 5)

1) Check your antenna, tune to a local radio station frequency, AM or FM and
see if the bandscope is working. If it is, then we have to check out the
audio. (I assume the controls all look as if they're working.) goto step 3)

2) If no joy on the bandscope then something is wrong with the RF/IF
section, or maybe the CPU/EEPROM. From your email, It looks like you can't
hear on any of the PCR's bands.   It might be worthwhile checking that you
have the correct COM cable supplied by iCom. I think details of the correct
cable have previously been posted to the list. Try loading default eeprom
values as a last resort. If that fails - consider getting iCom to fix it.

3) If the bandscope works - see if the radio works on the internal speaker.
(Debox the set and switch the speaker switch to internal. )

4.) If that works, then you have to check audio cable from the line out of
the PCR1000 to the line in of the computer is OK. I think the line out of
the PCR1000 is a mono connection and the line in to the computer is stereo,
so if you get the cable the wrong way round, or wire it incorrectly, there
might be a problem.

5.) A temporary fix is to use spectrum lab to connect the input to the
output. Apparently its possible to gippo the soundcard installation. Working
on it.

I don't particularly like scrapping a Rx - unless there's lightning damage
and everything has blown. See what your local agent can do. Apologies if
this all seems a bit simple - sometimes we forget the simple things.

Best of luck with it,
Bryce
