K3- hearing 10-11m above 44 MHz

[mic]

Hi,
I'm hearing, for example, K6FRC/B2 beacon on both 28.250 MHz and 44.676 MHz
First IF 8.125 Second IF 15 KHz my math is not working.
Also hearing some very strange call signs up there :)
Anyone else hear it with AGC off pre amp on?
Or is it just my receiver
Thank you,

Hi Mic
The IF is 8.215, so the image will be on 44.68MHz.  Or listening on
44.676, the image will be on 28.246. Does this explain it?
BTW, I found that the main rx had quite good image rejection, but the
subreceiver is not so good. I designed a filter for the subreceiver to
deal with this - http://www.g3tct.co.uk/k3.html

Thanks for the reply Graham.
I did see your K3 website, I'm a 1 week old newbie here.

Yes I posted an incorrect IF.

I have only the main rx here and have since
found the specs for image rejection >70db 48-54 mhz
making my post for the most part unworthy of attention.

I'm having a great time with the K3, first new rig in 28 years.
Thanks Elecraft, you're on it!
