Its called adjacent channel rejection, if your unit is not properly aligned
this can occur.
PL or not if its poor on rejection then you get bleed over, the same kind of
thing that happens when a trucker goes by pushing excessive wattage from his CB

First of all, MAKE SURE the cavities will tune down to the ham band
A lot of time the rods are cut and there may not be enough rod to tune

How long are the rods above the top of the nut assembly?

That is correct. No external antennas and no amps are allowed by FCC rules.
These radios are operating in a 902 ham/Scientific band so you can expect
that operations will be noticed by amateurs on the band even if they are
FHSS if you are running any significant power. They are allowed on a

Hi guys.
We finally secured a brck type UHF amp for our hamtronics machine.
The Hamtronics puts out 7 watts after all the filtering into my Bird
Termaline wattmeter. This needs to be knocked down to below 4 watts
so as to not over drive the outboard amp. I had 2 options - one is to

Hello All,
Does anyone happen to have a Micor IMTS Station manual? If so, I'm
looking for how they locked an M6709 into long squelch mode only. I
think that it just may be a resistor (not sure what value) to go between
two pins of the chip or from one particular pin to ground.
Any help
Brian,
Why would you think you can't use an amp (or higher power) on 900 MHz as an
Amateur? My repeater station is 150W, with added gain via the antenna
system; my mobiles are 12W (but there are 35W units available), and my HT's
are 4W units...

Those filters are the standard 16K0F3E filters, for 25 kHz channels. The

As long as you run your callsign as the SSID and are within 902 to 928, you
can run all the power you want. (up to 1.5kW)
A few things to keep in mind:

There were certain regs pertaining to the use of the FHSS radios on 902.
You would need to check into the FCC rules re. that.
I understand your point that the antenna and amp limitations pertain to the
unlicensed use of these low power FHSS units, we agree there.
But there are also specific

Can anyone provide some information on the Kenwood TKR-720 repeater?

- In general, is it a good repeater?
- Can it be easily tuned down to amateur frequencies?
- How
