[Coco] COCO 3 for LowFER transmitter?

[Jones, Orville CPT]

Hi James,
Sorry I took so long to reply to your message. I believe you could use the
CoCo to key a CW signal no problem, but I don't think you could convert the
rf modulator to transmit a A.M. signal. I am not an expert on the rf
modulator, but I would think it would have to be at a VHF frequency and
"frequency modulated" not "AM", but I could be wrong. I would have to look
at the service manual which I don't have a copy of here. What kind of HF
gear do you own? If you are only going to have a beacon on one frequency
then you could build your AM transmitter from a kit and save a lot of money,
then let the CoCo do the beacon stuff using the cassette port relay as a
keyer.

Dear Alan Jones,
I have a COCO 3 that is still in great shape. I would like to know if I can
use it as a LowFER home-brew beacon transmitter for operation at 160 to 190
kHz 1750 meters? As to send Morse code, AM, and use it as a transmitter all
in one. Since it has a output of Ch, 3 and Ch, 4 wide band how could I drop
the frequency and narrow the bandwidth to less than 100 Hz without opening
her up? I will be using FCC Part 15 rules. Any info you can send would be
welcomed.
