[Elecraft] 500 kHz Receive Operation With the KX1

[Mike-WE0H]

Hi John,

I use that Jackson Harbor receive converter in my 2200m thru 600m 
transverter. It has worked very well for many years. The buffer amp is 
not needed for those bands as there is plenty of received signal using a 
resonant antenna down there. hi hi...Lots of signal...I did have to add 
in back to back 1N4148 diodes on the input of the mixer so it doesn't 
get clobbered if I mess up with the T/R switch. I also use a 7 pole LP 
filter tuned for 520kc in place of the original LP filter.

Info on our 600 meter Experimental Band is at www.500kc.com

Performance has been better than expected given the time of year and the high amount of QRN in this freq range. For $14 I've added a new receive band to any of my 30m QRP rigs and it's kinda fun to tinker and explore what's down in that range. I was unaware of the fact that several stateside stations are operating at 500 kHz.
