Hi Kenny & Scott,
Thank you to both for the very kind reply to this. Basically, I am
trying to use the same digipeater UHF Alinco radio to function both as
an APRS digipeater and SSTV repeater.
I agree with Scott and did not think about the fact that the simplex
repeater will digipeat everything it hears including the packet data.
I believe requiring CTCSS tones for the will disturb SSTV
transmissions so that might not be an option.
Are there any more possible solutions to this before we decide to
abandon this project?
