Re: [Elecraft_K3] Need volunteers to try an even better version of KAT500 firmware (rev. 1.63) -- more accurate initial tunes

Rick WA6NHC <HappyMoosePhoto@...>
 

Wayne et al,

I installed it this morning and retrained for 160 and 80 meters (104 meter dipole at 30-40'). In general, better matches were found on 160 (now the entire band is <2:1, surprising since it isn't a high antenna). There were a couple 'bumps' in SWR on 80 meters but since it is starting to rain (yay!) here in the Sierras and parts of the wires are tree suspended, it isn't surprising; all better than 2:1 (bypassed ranges from 20:1-10:1, with the 4:1 choke). The moisture in forms of humidity and rain make small but significant changes in SWR (window line, non-insulated antenna wire). This week will be a challenge for the KAT.

The retraining involved both the initial and long tuning cycles, often slightly better matches were found.

While the utility sets the KAT for long tuning on 160-60, it generally uses the short cycle by default.

Time to play!

I will be making improvments to the antenna (adding another 35' of wire) to improve native resonance. Two questions: Is there a way to clear the fault table other than a full factory reset? Since I leave the station on 24/7, the time stamps are meaningless to me.

Is there a simple means to extract the memory settings (show LC values at band segments) so that a table for comparison can be made (for event/weather changes as an example)?

To me, those could be REALLY useful features of the utility program. Even better if I could easily print them out (without cut/paste).

Thanks for all your (team) efforts!

Hi all,

We just posted a new beta-test release of KAT500 firmware (rev 1.63) that does a better job on initial tunes than the previous release (1.58). We'd really like to get this firmware into production quickly, but to do that we'll need some testing help.

If you can spare a few minutes, please do the following:
1) Save your current configuration so that you can return to it if necessary

2) Install KAT500 rev. 1.63 (follow instructions for beta releases)

3) Erase memories on at least one band where the tuner has to work to find solutions (that�s 160 through 40 meters for most of us)

4) Do some full-search tunes.

The KAT500 should find very good tuning solutions (within its specified impedance-matching limits, of course). Please send me your results.

Thanks--

Re: [Elecraft_K3] K3 Mic Connector Question

I would explore the possibility of a ground loop or some kind of coupling. 

Does the issue occur when touching the plug with a insulated device or just your hand?

I would also try disconnecting digital mode equipment and perhaps anything not needed.

Have you taken apart the microphone cord connector to make sure the

After reviewing the assembly manual, you may be able to see the 8 pins of

Sounds like a bad or broken solder joint back there Torrey. Should not be a big problem to check it out as you are a kit builder. If I remember I believe you will have to take the board off the front panel to get at the mike connections. Just take your time with that front panel.

Hi,
The latest release of Win4K3Suite Server now supports remote spectrum scopes at 44.1 kHz for the KX-3 and LP-Pan.
The documentation is at http://va2fsq.com/?page_id=945.

Please note that Win4K3Suite can also be integrated with NAP3, HDSDR, and other SDR type software by using Win4K3Suite's AUX / CAT port.

The remote capability applies to these third party software packages as well.

Thanks for all your support!
