[ICOM] CI-V "transceiver" mode?

Wed Apr 27 13:18:35 EDT 2005

I built an antenna switch last summer using a PIC as Mike suggests.  It 
sits/ listens on the serial link... monitors the data looking for the BCD 
frequency words and remains latched until one is found.  It then has a 
built-in look-up table basis the MHZ.  It drives some small relays (10 band 
segments from 160-10), has an interconnect to daisy chain the auto switches 
(providing lock-out for multi radio operation/ same antennas), and has a 
manual over-ride using a simple BCD switch input (either select a 
band...160-10, or AUTO).  I programmed the PIC (16F877) in BASIC in about 15 
minutes from start to finish.

The real reason I started the project was to provide a pulsed output from 
the PIC on band-change.  I have an auto-tune commercial amp, but it needs to 
be TOLD that you are changing bands with a pulse (which my auto switch 
provides).  I suppose I have $35 in the whole project, not including time 
and programming software.  I suspect someone should be able to generate a 
kit easy enough.

The analog output from the ICOMs for switching is a waste of time... it 
won't work, because they use, in some cases, the same filters (the reason 
for the output in the first place) to cover different bands... unless you do 
that with your antennas too?

Hi Mike (and gang),

Thank you for the suggestion...  I actually tested the analog band data
output first and I was dissapointed to discover it did not provide
unique outputs for some bands (12 and 17, for example)...  I really
wanted a decoder that would decode all 10 bands (160 through 6)...  By
using the CI-V "frequency record" I can decode all ten bands with an
antenna "memory" for each band (as well as each single MHz of general
coverage spectrum)...  My controller also has BCD I/O for fully decoding
(or encoding) Yaesu type 10-band BCD band data...
