thing I have played around with is surplus FAA AM gear that can be operated
on 144.400 Mhz. Although I made only pre-arranged contacts in the past I was
curious if there are any reports of 144 Mhz. activity in the Houston, TX.
area ?

used in some area due to interference from other modes. I guess I will find
out soon but I thought I would ask.

Hate to invest in crystals I can't use! This unit is the TRX-102, a 1972 era
design that has a good sensitive receiver and about 5-7 watts out.If others
are interested I have written down the conversion info.

transmitters that cover 144 Mhz easily, these are the TV-6. They have a
4X150 final modulated by a pair of 6146's. These units are beautifully built
with all sealed transformers, about 3' tall rackmount, about 130 lbs. I have
one set up on 144.400 that easily puts out 50 watts of nice sounding AM. I
believe I have 2 or 3 checked out and wrapped up in protective coverings in
my shop.Have a full manual for it too.Have an extra tube-type receiver {RV-

system will be high performance { pair of 18 ele. yagis at 100'} so will
have 250 mile plus range.
