Hey guys... I have a fan on the transmit radio, but as I don't want to run it all the time, only when transmitting, I'm going to drive a relay from a GPIO pin off of a URI instead. I found two excellent resources as a basis for what I'm after: http://www.qsl.net/k0kn/txfan http://latinovoip.net/allstar-and-the-gpio-fan-script-for-dmk-engineering-ur... I setup the following in my node stanza: [2376] events = events2376 [events2376] touch /tmp/RPT_TXKEYED2376 = s|t|RPT_TXKEYED rm -f /tmp/RPT_TXKEYED2376 = s|f|RPT_TXKEYED As you can see, this is pretty simple, write RPT_TXKEYED2376 when the RPT_TXKEYED variable is true, remove when false. I even checked for the presence of those variables when the repeater is keyed/active from doing a "rpt showvars 2376": as2376*CLI> rpt showvars 2376 Variable listing for node 2376: XX_RPT_TXKEYED=1 RPT_ETXKEYED=1 RPT_TXKEYED=1 RPT_RXKEYED=1 RPT_NUMLINKS=0 RPT_LINKS=0 RPT_NUMALINKS=0 RPT_ALINKS=0 RPT_AUTOPATCHUP=0 -- 9 variables Everything suggests this should work, but it is not for whatever reason, which leads me to two possible guesses: - the logic is not placed correctly where it needs to be in rpt.conf - chan_voter does not talk to the event management subsystem Any ideas? Kinda lost... Thanks, Stephen K1LNX
