K3 Receive 500 - 700 KHz

William Shappley-2

Yep, just did it tonight on K3 serial number 175 - works great!  
Listened to WSM (650 KHz, showing S9 + 40 but I'm close) and some  
others.
Mostly you hear AM broadcast radio stations, of course.  I also tuned  
around the 2-3 MHz areas and found the nearby shortwave station
(WWRB) and the 6 MHz range, it all works.

I do have the KBPF3 installed and the 6 KHz AM filter.  AM mode, or  
course (firmware version 1.55 downloaded).

The alternate AM mode (AM synchronous) is not in the firmware yet,  
apparently.

73,
Bill

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!
