The KX3 doesn't have sufficient filtering for transmit at 472 kHz, nor much gain at this frequency in the PA. I would suggest using an external transverter for this band. For receive-only use, you could add a 500-kHz low-pass filter to eliminate any images due to local oscillator harmonics. > 2) regarding the 2 meter option for KX3 (which will be available in > September, as far as I know), I would like to use it with DB6NT Microwave > transverters which could be controlled in TX mode thanks to a + TX voltage of > 5 to 12 V on the inner conductor of SMA antenna with a very low current (to > the base of a low-power switchîng transistor).

Yes, the KX3-2M (and -4M) module will include a switchable DC voltage at the antenna. > 3) same question regarding BNC output as 28 or 50 MHz could be also used as > IF for 70 / 23 cm transverters . Sorry, there's no provision for DC at the BNC output of the KX3. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
