I have used Mini Circut Labs ZFSC-2-1 and a 2 port passive Stridsberg. I
obtained the MCL's at hamfests for $10 and the Stridsberg new Presently I
am using a MCL PSC-3-1 to feed 3 receivers. I also got this at a hamfest.
My receivers make up the nearly 5 db loss.

question. anyone recommend the rf-system-SP-1?
or the mini-circuits- zsc-2-2? or, what are you
using and why? looking for suggestions...
thanks...

How do they make up the loss? Just curious.

I have an excellent splitter for sale, please contact me at


I tried emailing you but your email bounced

Maybe his radios have pre-amps like the Drakes.

When you use a passive splitter the loss is 3dB power and 6dB voltage. I
think most radio S meters are responding to the voltage number due to
the nature of the AGC circuits. Someone can correct me on this. Should
be easy enough to take a splitter in and out of line.

Almost all modern receivers use teh AGC voltage for the
"S-meter". And very few have any meaningfull calibration.

Correct me if I'm wrong... but would it not be better to run some
pre-amplification ahead of the splitter rather than try to make up something that
has already disappeared? Much the same in say VHF work where it is better to run a
receive pre-amp right at the antenna versus running it at the receiver end of the
coax?

I'd never consider using a passive splitter here, and I rarely if ever engage the
pre-amps on the receivers... no need.

Yes, the calibration may indeed be off with various manufacturers, however all
things being equal it should be very easy to determine various antenna changes
with a 'particular' receiver.

Damn simple.

Most outboard amplifiers cause more problems than they solve. Listen
with your ears, not your S-Meter.

I don't use any outboard amplification here 'tard boy, other than that which the
Stridsberg uses to overcome the loss to support up to 4 receivers.

I'm fairly certain I've done my fair share of listening, you just keep on trying to
catch up.

Please, get a clue, and try to get a grip.

Continue to tote.

The results might surprise you.
When I received my zfsc-2-1 I expected the addional ~3.5dB loss to be
an
issue. But after much testing I found that it didn't make that much
difference.
For the most part any signal I could receive without the addtional loss
was
still present with the loss. I used a HP step atenuator to check this
before going to the trouble of mounting the zfsc.

I really expected to need a good low noise, high intercept, preamp
before
the splitter. If you have a "good enough" antenna the additional loss
is of slight concern.

Since I have all of my antennas, receivers, RF filters on a patch
panel,
it allows me to easily move the splitter out of line. I use BNC
connectors
because I was given a "boat load" of them and find them easier and
faster to move then PL/SO-259 connectors.

A friend wanted a similar setup and I gave him enough bulkhead mount
"F" femalefemale to allow him to bring all of his antenas and both
receivers to a panel. He found an "old" TV spliter that works very well
to below the MW/BCB band. I bought a bag of over 500 for $1 at the
local Goodwill store.

Another advantage of a RF patch panel is I can connect my Pro2004 IF
out to my R2000 so I can listen to SSB VHF/UFF comms.

I do have to be very carefull to insure that I don't connect my ham
gear to
my receiver inputs. At them moment I have them feeding different RF
patch
panels and simply don't ever connect my ham gear to a receive antenna.
I am considering switching all of my receive RF connectors to "F", at
least
at the patch panel. I have thought of using TNC but they are expensive
and are easier to crossthread then "F".
