Valid options perhaps, but not what I'm looking for. I want to be able to show the users that all is well and (hopefully) they'll stop being so paranoid every time the repeater signal is down a quarter of an S-unit on their 35 year old rockbound radio.

I think it was an MFJ-52, but not sure. You have to make a packet connection to the TNC using the X1J4 firmware and the TNC will respond with the deviation and signal strength of each station in the MHeard list. You can also query for supply voltage and temperature. I am sure you could substitute power out and power reflected for the last two params, and use the repeater as a packet node to get these values. I just installed a regular packet node on a mountaintop and used one of these boards, but did not hook up the hardware for the voltage monitor or temperature. The deviation and signal strength come in handy for keeping up with the various packet stations the node services. The receiver condition could also be monitored using this setup and connecting from a fixed location with a power output that would not saturate the first limiter of the receiver, where the signal strength is picked off. The most stable signal strength I found was from another node about 150 miles away that normally read about S-8 but would vary with the weather conditions. 73 - Jim W5ZIT --- Burt Lang <[EMAIL PROTECTED] <mailto:burt%40rocler.qc.ca> > wrote: > There is an another option.
