Hello Byron,
The M57729 is a standard Motorola PA Slab.
Yours is the Kenwood Part number, M57729h-01-P.
The standard Motorola module will be available off the shelf,,, BUT,,, it will
be priced @ $230.oo US.
Any equivalent Motorola, or spurious part [30W UHF] will do the job, much
cheaper,,, you can cross reference on any good RF Components web site in your
area. You may source one from a scrap [ out of spec ] mobile PMR radio for
$10.oo, if you know where to look ! 25 watt would be much cheaper and easier
to find.
Hope this is of some help. 73 from Ireland.

there is a company here in New Zealand that used to or maybe still does deal
with Kenwood products

I know of no one else, other than Kenwood themselves

Hi
Does anyone know of a good source for a M57729h-01-p.
It is the UHF power module in the Kenwood TKR-820.
It is rated at 30 Watts 12 volts 440 to 470 MHz.
I found that they do not like to be operated into the wrong side of a
duplexer. For even a short time.
Is it used in any other transceivers that might be purchased for the module?
Thanks
