I forgot to mention that I've also had good luck assigning multiple Parallel port pins to PTT in usbradio.conf or simpleusb.conf, such as: pp3 = ptt pp4 = ptt Again, I'd rather not cycle a relay with every PTT. I'd much prefer the fan run for 2 minutes or so after the last PTT, then shut off. That would save a lot of wear and tear on the fan and relay. My setup is probably a bit unusual, as I have several transceivers cooled by one large fan. It's occurred to me that I could always build a 555 timer circuit to use along with my fan control, but a software solution should be just as simple. I guess I'll have to try to hack the TXFAN script I used on IRLP? 73. Kyle K0KN
