Appreciate the information.
I will dig the scope out and have a look at all three voltage rails.
I have not had a chance to try the password yet.
I totally agree that having a service manual will be necessary to most likely
fix this thing properly. I at least have a Motorola 2600 service
Check with RF Parts (www.rfparts.com). Years ago I purchased a power module
for an IC-2710H Icom and it was about half the price than Icom.

I would look for a shorted tantalum capacitor hanging
somewhere on the
10V rail.
I agree.
If you hook 10V from an outside source to the 10V
buss, you'll
probably find it's drawing all kinds of current. The 10V regulator
circuit will go into fold back before burning up. This is by

Whenever you have a shorted component, such as a tantalum capacitor, the
current drawn by that short might burn out a PC board trace before burning
up the capacitor. If that happens, finding the original problem becomes
much more difficult. Perhaps a better and safer tack would be to use a

This is also a good place for the 'finger test'. If there are suspect
components you can get to that can't easily be removed (by pulling boards,
etc.) then a calibrated finger will often lead you to the defective
component. If it's really a cap, it should be generating a lot of heat.

Thanks for the replies. I don't have the high end equipment to do some of the
testing mentioned. I do have a service monitor and a dummy load, along with
numerous receivers. The dummy load is kind of suspect (old and not really
liking the strange signals I get from it at times) but it is all we
Hello all. We have a cross band repeater (Midland 100W VHF low w/ 1W VHF high
band repeater built in).
What we noticed is that in the High Band -- Low Band direction, the high band
side will receive the signal, then the low band Tx will key up to repeat the
signal. Normally, all works just

Hello all. We
A few questions to which the answers would be extremely helpful:
* What are the frequencies in question?
* Are they harmonically related?
* How much vertical separation is there between the two antennas on the
tower?
* Are they directly one above the other?
* What is the gain of the two antennas?
Brian,
I will contact you off list re: a repeater I have that would fit your bill
perfectly.

Because of the limited amount of storage space Yahoo allows for group files,
you will find FAR more information on the Repeater-Builder website than in
the Yahoo group files.

I have a small amount white noise on the TX of a Micor repeater. It is most
