K3 in ARRL10

Hello,

well, I read some emails here about K3 performance in 10 mts band but really
I never tested it carefully.

We started ARRL10 with the K3, very poor condx in the morning, good in the
afternoon.

Second day in the morning we didn´t heard any signal in 10 mts. Some of the
guest operators told me to listen in my TS850, the radio we used in the last
2-3 years that we did the ARRL10 from El Mangrullo.

We heard two or three very weak signals from PY in the TS850 that were not
heard in the K3..!, I didn´t want to assume that, I said for myself
"NOooo", after spending +$4.000.- on my fully K3 for contests!..

So I hope it´s all about that I don´t know how to use the K3. It has a lot
of features that really I do not understand so I think (and hope) I am not
doing a correct use of the K3.

Any suggestions are very well apreciated.

73,
Jorge

Noticed that here, too, in Arizona using a TS-480.

This seems to come up every year after the ARRL 10M contest. Perhaps an extra 10dB of i.f. gain on 10M could be programmed into dsp firmware.

If these reports are correct, then additional I.F. gain isn't the answer.

In the past, I resorted to going into CONFIG FLx Gain and dialing it up and that helped a lot. IF Gain WAS the answer for me.

However, I understand that some folks are resorting to external preamps for 10M.

True.

True, maybe all of them. Mine is deaf too. My TS-870 isn't.

Re: K3 in ARRL10

Even though I do get a rise in band noise going from dummy load to antenna, I still hear weak signals on my 480 that I don't hear on the K3 on 10 meters SSB. Not sure about cw (what's cw?) :-). Assuming my K3 is set up properly, I would hate to crank up the IF gain just for 10 meters.

I operated the 10m contest this weekend with my K3 and I did have the
preamp on. In that condition, I heard a lot more than apparently could
hear me.

If this could be quantified some way, perhaps we could get away from just
comparing opinions?

Re: K3 in ARRL10

Hello,

Sorry for the delay, but I was in a 6 hours drive trip yesterday.

After reading the emails, I stopped at AC7AC email. I am very sure that I
have band noise. I heard a noticeable SHHHHHHHHHHHHH that I didn´t heard in
the TS850. I can do some records later this week when I go back to the
station.

My setup is a ArraySolution sixpack, so I switch the 10 mts position to the
K3 and TS850. The radios are connected to different models of amps and swr
meters, but I don´t know if this will affect.

I didn´t use the PRE.

73,
Jorge

Re: Res: Re: K3 in ARRL10

Initially my K3 copied much worse than IC-7000. Turned out that by mistake I pressed the RX ANT button and was using K9AY as a receive antenna.
After changing, K3 copied slightly better than IC-7000.
Previously, I upped gain on the 400 Hz filter.

Hi Jorge,

If you are listening to weak signals on 10m with a K3, the PRE should
be on. It's really required unless your local 10m ambient noise is
terrible.

The FT1000MP built in this change in sensitivity, so it always had
additional sensitivity automatically turned on for 10 meters. This
could be turned off in the menu.

In the K3, the operator makes these choices, it's not automatic. In
general, the PRE should always be on for 10m. By contrast on 160m,
the ATT should be on and the PRE off, unless you are listening to a
beverage or other low level RX antenna. But these settings are left
entirely to the operator.

Those who have a high-end external preamp for ten meters (particularly
remote pre-amps) will want the K3 internal preamp off. That is one of
the number of reasons why it is left to the operator to determine the
proper setting of PRE/ATT to match the ambient noise at the ANT jack.

Once the proper setting for your circumstance is determined, the K3
will remember it so you don't have to adjust it constantly.

73, Guy.

Re: K3 in ARRL10

Hi Guy,

Thanks for the suggestion.

Will try 10 mts with the PRE next time I go to the station. Unfortunately I
didn´t tried it during the contest.

On low bands sometimes I don´t need to use the PRE with my beverages, very
good RX there.!

To be compared with K3 with PRE OFF, the TS-850 must be with AIP set to ON

In reply to this post by Guy, K2AV

Listening to 10m on a K3 with PRE off definitely would give the
appearance of "insensitivity" if compared to a RX that switched its
preamp on with a band change, or had the extra sensitivity switched
in.

Just one more reason that science grade RX comparisons are difficult
and require established protocols to do it right.
