[Elecraft] KBPF3A < TT Jupiter on Broadcast Band

[Carl Jón Denbow]

I recently installed a KBPF3A in the sub receiver.  I've been surprised 
to discover on direct A/B comparisons using the same antenna that my old 
TT Jupiter is much more sensitive on the broadcast band.  A station that 
comes in at S-6 on the Jupiter is maybe an S-2 on the K3s.   This is 
very noticeable to the ear, as you might imagine.  I'm wondering if 
anyone else has noticed that the KBPF3A is not exactly optimized for the 
broadcast band.

Also, I have another issue related to the Jupiter and the K3s.  I tried 
to install my new SP3 so that I could switch between using it with the 
K3s and the Jupiter with the front switch.  However, when I hook the K3s 
to the SP3 when the Jupiter is connected, it immediately mutes the 
speaker.  I can then switch to the K3s connection, and it's working 
fine.  Switch to the Jupiter and it's muted, unless I physically 
disconnect the K3s in the back of the SP3.   I've looked at the rather 
simple schematic of the SP3, and I can't figure out why this is 
happening.  It appears to me that something must be shorting ring and 
sleeve in the K3s, but I can't exactly figure out how his can be 
happening.  Any help would be appreciated.

73,
