I did an experiment with 600-meter transceive on the KX3 (around 500 kHz). With the ATU installed, which provides additional filtering for the broadcast band, the transmitter put out about 0.5 to 1.0 watts. But additional low-pass filtering would be required, and as noted above, receiver sensitivity is reduced in this band due to the high- pass filtering.
73, Wayne N6KR --------------- I tried keying the KX3 at 495 and 508 KHz and get BND END warning (probably because it is below edge of 160m). How do you defeat the out of band restriction? 0.5w output would work very nice for me as I currently only use 0.1mw to drive my 100w converted Southern Avionics Non Directional Beacon xmtr (used as a high-gain linear amp). The NDB is usable from 250 to 600 KHz by simply tuning a slug-tuned one-pole BP filter. Adding a preamp is an easy fix for receive as is a BP filter for 500-KHz. I currently have a three-pole LP filter for 600m. 73, Ed - KL7UW survived the 980mb massive storm last night (mostly affected Anchorage 70mi north of me). ______________________________________________________________ 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
