Subject: [Repeater-Builder] help icom f121s
need help i have icom f121s for repeater use i have every thing setup
use cat controller but i turn on the rx exo to on and turn off the
delay
timer off but when i check the horn cable i does not do nothing stays
to
ground no changes of voltage as cor or cos can any one help me
please.
Carlos,
I am not an expert but I don't see that you have received a reply
to your request, so let me offer a suggestion. I am using F121S's and
F221S's in a repeater application. I believe you have the RX EXO set
correctly. I believe that the horn output will either be ground or
floating. You will need to use a pull up resister or voltage divider
resisters to obtain a COS logic state.
Hopefully one of the experts will come onboard and offer a more
authoritive answer to your question. If not, let me know. I can
suggest someone who will help.
Best good luck to you.
