K3 deaf on 6m comparing to a FCDP+ ?

Hi everybody,
since I own a FunVubeDonglePro+ I think my K3 is a bit deaf comparing
those 2 rigs on same antenna.
Even with switched on preamp on the K3 it's sensitivity is worse to the
FCDP+
I only heard about that the K3 is deaf on 6m but never had a comparison.
Is there a fix to make the K3 hearing better on 6m ?

Re: K3 deaf on 6m comparing to a FCDP+ ?

I use a separate 6m preamp for the K3. Helps out tremendously. With the advent of the new PR6-10 on sale, you can pick up a PR6 off the reflector for sale. I recommend it highly if you want to use the K3 for weak signal work. I also use a Collins laboratory preamp from Dr Jack Smith (he is on this reflector) and that works great on 6m plus HF.

Good luck!

K3 deaf on 6m comparing to a FCDP+ ?

In reply to this post by DK5EW

Hello Erwin,

No doubt K3 is deaf in 6m. This is the reason why there is PR-6 or PR6-10 pre-amp offered by Elecraft. Upon the installation of those pre-amp, K3 is in par with other radios in 6m under the same class.

Apart from the choices from Elecraft, you may consider http://www.ha8et.hu/ extra-6 which is contest grade pre-amplifier.

To be fair to K3, if local RF noise is high in your area, pre-amp will not help you anyway.

TNX & 73,

Johnny VR2XMC

Re: K3 deaf on 6m comparing to a FCDP+ ?

Hi Erwin,

second that. I use the Extra-6 by HA8ET for the K3 and you already have an
Extra-2 so you know their quality. ;-) Besides this it is way cheaper than
the PR6 by Elecraft. ;-)

Re: K3 deaf on 6m comparing to a FCDP+ ?

In reply to this post by DK5EW

Hi Erwin,

I own an "old" K3 (#1212) and a FCDP+ too.
Without a PR-6 (or an other low noise preamp)
i admit that the

FCDP+ is better on 6m, speaking of sensitivity only.
I bought the PR-6 after the K3, when i was
a little bit
disappointed with the K3 6m
sensitivity.

My best 73,
Rudi, HB9ARI

Re: K3 deaf on 6m comparing to a FCDP+ ?

Hi dear Rudi,
yes so far I learned that a preamp is needed for serious 6m operation
with the K3. TNX for your info as well.
*****
As you write you use also the FCDP+. How do you use it together with the
K3 ? Is there any circuit out there ?
Or better is there any hint to connect it to the K3?
*****
Would be nice to have such a solution.

Re: K3 deaf on 6m comparing to a FCDP+ ?

Dear Erwin,

I use a RF Splitter to feed the same
antenna to both K* and FCDP+
but only for receive tests !!

I've done
also some tests during JT65 decoding, using
the same set-up, but with a different antenna hi!

You can find some
results at the end of this site:

http://www.von-info.ch/hb9afo/articles/funcube/funcube.htm

I dont' use the K3/FCDP+ combination for actual TX/RX use,

only for receive tests with the splitter.

My best 73,
Rudi, HB9ARI

Re: K3 deaf on 6m comparing to a FCDP+ ?

In reply to this post by DK5EW

Those of us who have built high IP3 contest LNAs for 144 and 432 MHz will have no difficulty to make one for 50 MHz. K3 dynamic range on 6m is excellent, so LNA has to be equally good.
Unfortunately this is not the case with K144XV internal 2 m module, where according to my contest obsevations, dynamic range is almost non-existant. The July 3rd Subregional IARU R1 VHF conest was a disater with a lot of parasitic signals across the band even from S9 stations.
Tring to figure out what's wrong b4 Septemer IARU R1 VHF campionsip.
If successful will publish the findings.

Re: K3 deaf on 6m comparing to a FCDP+ ?

In reply to this post by DK5EW

I'm a little late to this thread because I receive the digest version of
the reflector, but I thought I would weigh in anyway ;-) I don't know if
it matters that much on 6m, but the blocking IMD of the FCDP+ doesn't
compare in any way with the K3. My tests show about 80dB before onset of
blocking (at least on HF where I tested). That's probably about 40dB
worse than a K3 with high quality preamp.
