Dear Friends,

I've a friend who own into his amplifier collection an HF Amplifier from
HARRIS model RF355 and he's trying to locate the information concerning the
commands to be sent over the serial RS232 line to drive the internal antenna
tuner automatically.
This kw HF amplifier was initially designed to follow an HARRIS RT1446
transceiver.
Could someone help in this search?
May be there are on this newsgroup some OM who worked in the past at HARRIS
communication division in the US or in the UK?

Telford Electronics has manuals for the thing.

Harris, though, still supports it since it is still a current military
issue item.

They will also work with the RF-350K transceiver... a 350K or an RT1446 service
manual may have the details.

As I recall, there are two different ROM versions for two protocols. One is
a Harris-proprietary block protocol that has checksums at the end of each
block, and the other one is an ASCII protocol.

Peter Gottleib has some BASIC code to drive some of the Harris gear from
a laptop... years ago he was peter at newyorknerd.com.
