Re: RFI on 2 meters from uBitx

Ashhar Farhan and Raj,

The original email stated that it was there on both transmit and receive.  I think that should rule out the relays, any of the transmitter amplifier stages, and the antenna match.  I guess it is possible that a bad match could affect the 30 Mhz LPF at the input to the first IF,  Still, the double-balanced mixer should isolate the LO from the RF port.

Am I missing something?
