k3-broadcast band reception
Locked
 
|
Dave W7AQK reported in his Dec. 29th post, 'K3 Performance', that he was having trouble receiving anything between 500-700khz on his K3. A later post from Dave informed us he did have the KBPF3 general coverage filter module installed.
This concerns me. There is an AM station on 630khz about 100 miles west of me in NC that I like to listen to during the daytime on my Yaesu FT-920. The problem with the Yaesu is that I get blow-by from a 600khz station that is located about 10 miles from me. I was hoping my upcoming K3 would eliminate this problem for me. I sometimes listen to WSM 650khz, Nashville, TN, in the evenings, but the Yaesu does ok for that station. I am not ordering a K3 just for AM broadcast band reception, but it sure would be nice if I could hear the lower end of the broadcast band with some rejection from stations close by to me. Would some of you current K3 owners please check and see if you can hear anything between 500-700 khz. Also, do you have the KBPF3 installed and use the AM filter? Many thanks and Happy New Year!

Works fine here and I can easily listen to AM BC stations in this range. Have a Gr8 '08!

This may be an overly simple response and I appoligize. Whoever is having
this RX problem from 500-700 kHz AND has the KBPF3 installed, is the KBPF3 set to ON in the CONFIG menu? It needs to be ON and then cycle the power. 73 Greg AB7R -----Original Message----- From: [hidden email] [mailto:[hidden email]]On Behalf Of [hidden email] Sent: Monday, December 31, 2007 4:35 PM To: [hidden email] Subject: [Elecraft] k3-broadcast band reception Dave W7AQK reported in his Dec. 29th post, 'K3 Performance', that he was having trouble receiving anything between 500-700khz on his K3.

Larry and All,
Well, I think you can relax. My K3 is now receiving at 580, and seems to be doing so properly. It was interesting though. Several times I had verified that all the settings were right, and that the KBPF3 was engaged. Those settings were fine, and I wasn't hearing anything below about 620 khz. So, I tried changing antennas, and in preparation for doing so I disconnected everything--power, antenna, etc. On a different antenna, I could hear my local station at 580 khz just fine. Then when I switched back to the original antenna, that worked too. So, I basically attribute my problem to something akin to what computers often require--a complete power down, including power disconnect, and then power back up. That I had not done previously since first noting the problem. Since then I have checked several times, and everything is A. O. K. on broadcast band reception. As far as I know, nobody else has had this problem, so I think you are safe to assume it's not a concern.
