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,
Carl
