I have my Flex 5000A back from the VU upgrade (I guess its time to look for VHF/UHF antennas) and my HFRIO board has been fixed. I didn't realize how much I'd miss the radio.
The RFIO board problem has me a little concerned. This is the second time in a year that it needed repairs. This time it needed 3 PE4259 SSRs and a TSB41AB2 IC. Does that give anyone an idea of why it failed? I understand that muting RX2 when you transmit doesn't disconnect the RX2 antenna in the radio. Maybe that's the problem. I routinely listen on a beverage (RX2) while transmitting on a dipole. The beverage is located below the dipole. When the board went south I was generally running 100W of power. I now have a 1 KW amp. I don't dare try my combination with the amp. Of course, the board may have been damaged by nearby lightning. I have purchased some ICE arrestors and will have them installed before the spring thunderstorms come along. So, I have two questions for you experts out there. 1. Do you think the board fried because of too much of my power getting into RX2 or because of nearby lightning strikes? 2. If I switch RX2 to NC in the Antenna Selection window, will that physically disconnect the antennas from RX2? Thanks for the bandwidth. 73 Chris KA1GEEU _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
