I am baffled.
Here's what I have: Flex 5K DEMI transverters for 222 and 1296 I have set the offsets for both on the transverter screen - 194 MHz for 222 and 1268 for 1296. All other parameters are the same. For both 222 and 1296. I have been using the 222 transverter with good results. In trying to get the 1296 set up, here is what I find: Without either transverter powered and a 50 Ohm dummy load plugged into the transverter port on the 5K: Selecting 222, noise level is -131 dBm Selecting 1296 noise level is -111 dBm A 20 dB difference!!!! Why should they not be the same? Both are a 28 MHz. input. After first making sure that 10 meters was open and I was hearing signals, I plugged the antenna into the transverter port but could hear nothing. Ok, maybe the transverter port has a pretty low sensitivity and needs more RF, as it would get from any transverter. So, then with the dummy load plugged into the transverter port, I tried transmitting while listening on a separate receiver. I heard nothing. Yes, it's only a few milliwatts, but I would think I would be able to rear it. Why should the noise level for the 222 and 1296 selections be different when they are both the same 28 MHz transverter port? Aa I said, all parameters on the transverter screen are set the same, except, of course for the frequency off-sets. Anyone have any ideas? Any help would be greatly appreciated. 73, Bill Tynan, W3XO _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz To opt out of the Reflector: http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz
