Hello all:
 
     If you are interested I can probably scrounge up a  NOS Motorola Maxar 
80 commercial FM transceiver, along with a crystal for  somewhere between 
144.275 and 144.300 MHz (I think I have a crystal for .285 but  have to 
check).  These are the same units that the Six Meter Beacon  Project  
_http://www.6meterbeaconproject.org/_ (http://www.6meterbeaconproject.org/)  has  used. 
 Output power can be varied; as stand alone 6 meter beacons the  units are 
set at about 35 watts output.
     I usually install an N0XAS pico keyer (programmable)  board that opens 
and closes the ptt circuitry. Since the unit is  transmitting a carrier 
with no modulation it is pure CW.  Not elegant but  simple and rugged.  The 
Maxar is about the size of a TR-751 or CB  radio and needs a 12v supply.
     If you want to hook it up to an amp I will have to  look to see how to 
get a ptt to the amp. 
     From past experience I strongly urge that whatever  you come up with 
be as close to plug and.  That means including a  power supply, feedline and 
antenna(s).
     
                                                                            
                                  73 and Happy New Year to everyone,
