The local ham club is converting a 2 meter micor mobile drawer for repeater use and the conversion works great except we would like to use a transmit pl tone. When we insert the transmit pl board and key the radio it wont unkey until the power is removed. Are we missing a step in the conversion or is this just not possible? Thank you, artman

There is a jumper on the exciter board between pins 8 and 10 of the board connector that is in for CSQ and needs to be removed for PL operation. If it is in, the "delayed keyed a+" for PL reverse burst will be kept up and cause the effect you describe.

It may be labeled JU402 or JU405 depending on the model of the exciter board

Are people seriously still converting MICOR mobiles to repeater service? Oh there are soooooo many better radios to use these days.

Granted these conversions work great, if they're done right, but sheesh... I dunno. I guess I've seen (or rather heard) too many that just didn't come out right.

The Micor has been and probably will continue to be the stable workhorse that it has become known for. Those out
there in the radio world don't always have access to the newer radios. So as the saying goes, you use what you
have or can find. As long as they can be kept working, they will continue to be the workhorse.

If you have heard of Micor conversions that have turned out on the poor side, then I would have to question the
technical ability of the person doing the conversion. It doesn't take a rocket scientist to do the work.

Thank you Sir, That fixed it!

That's sad. I have been hauling Micor repeaters to the dump for a year, no one wants them, not even the local hams.

Can't even get scrap for them.

That's cause the local hams have probably never had the opportunity to find out just how good of a radio the Micor's are.

If you were closer, I would come get them.

Micors kick ass. Whether mobile or station - they are nearly bulletproof, and have scores of available aftermarket products for them. MSF5000's ; you have to jump through hoops to make an aftermarket controller work. Quantar's? Don't EVEN get me started! A 6 m Micror repeater kicks so much ass that it's unreal...

com501, Ill pay shipping so you don't haul them to the dump!

Adding another emphatic hurrah for the Micor... It's simply the best at doing what it does.

I second, third or fourth. Had as many as 6ea of the 225W units as commercial repeaters. Never had a failure, with the exception of the cooling fan for the tube, which had to be replaced every 18 months or so. Replaced the tube amp with Vocom 250W amp's and they have been playing for over 25 years with no failure. Try and get any of the newer generation radio to last that long. Doesn't freak when glitzed by power surges, or lightning. Plenty of spare parts available, what could be better.
