Re: KBPF3 General Coverage Receiver -- Main or Subreceiver

If you only have 1 bpf module, I'd probably install it in the main, I guess.
I added a second one for my sub RX later. Opinions will probably run on both
sides, but I'd like to hear the arguments one way or the other myself. (not
that it really matters to me- as I said, I have it in both positions.

Re: KBPF3 General Coverage Receiver -- Main or Subreceiver

Thanks, Bruce, for your prompt response. I guess I'll wait for a few
minutes and see if anyone has a differing opinion, and if not, go with
the main receiver. 73 de Carl, N8VZ

Re: KBPF3 General Coverage Receiver -- Main or Subreceiver

My reasoning for this: You'll always have the main receiver enabled
but probably not the Sub-Receiver. Few of us run them both 100% of
the time.

Re: KBPF3 General Coverage Receiver -- Main or Subreceiver

Agreed. Perhaps another argument for placing it in the main RX, as
The sub RX has to be removed to install it. Best to get that out of the way
while you have it open... If you add a second one later, in the subRX, that
module would need to be pulled to install the BPF3 in it.
Also, with the (potential) new allocations for 137 and 475 KHz,
these may well become "main band" RX/TX functions in the future. (Of course,
the filter mods currently being beta-tested will need to be installed, and
some form of outboard TXPA driven by the transverter interface added for
those bands to get the full benefit...)

In reply to this post by Bruce Beford-4

Another vote for the main Rx:

I ordered the KBPF3 with my radio in 2010 and installed it in the
main Rx. I am on 600m already so it made sense to me to have it in
the main Rx. I didn't install one in the KRX3, which I also part of
my original order, as I expected to only use it for diversity
reception on eme which does not use the KPBF3.

Therefore, I will modify my KPBF3 when I order and install the two
Synth boards. Main purpose for getting the Synth boards is to be
able to operate on 630m (472-479-KHz). Of course it will help all
reception. I will be interested to see if this will lower the level
I can decode JT65 signals (typ -28 is lowest). Sorry, I drifted off topic.

Re: KBPF3 General Coverage Receiver -- Main or Subreceiver

I would also vote for main as I prefer to tune with the BIG knob. The Sub
knob is too crowded for my fat fingers and I frequently bump the RIT/XIT
knob causing undesired effects.

Re: KBPF3 General Coverage Receiver -- Main or Subreceiver

Thanks to everyone who responded to my query -- both on and off the
list. My hand has actually been forced a little on this issue, as the
KRX3 had a bad female TMP connection. It appeared distorted in shape
when I tried to replace the male connector. I then took the cover off
the KRX3 and discovered that the TMP female in question had never been
installed correctly and was actually a clear open. Some other aspects
of the board looked questionable to me, so I'm going to return it to
Elecraft for a repair and complete checkout. So far, everything else in
the rig seems to check out OK, though I haven't finished the shakedown
cruise yet. I'm also going to contact the seller and see if he'll pay
for the Elecraft repair. The unit was advertised on QTH.com as being
in excellent working and cosmetic condition. The one board seems to
have been otherwise, as I do not see how the second receiver could have
worked with all of its functions with one TMP coaxial connector
basically MIA.

73,

Carl
