Re: [Elecraft] KX3 guestion

[Adi Andrei]

Better hold off until the VFO tunning noise is fixed, or you will be quite 
surprized and once you hear it you won't be able to ignore it.

Wayne and Elecraft team . I have been holding off purchasing kx3

on this problem and that problem not sure what's fact and fiction.

[Elecraft] KX3: New VFO noise issue - out of nowhere, and not just on 6m,

[Adi Andrei]

I have KX3 #410, kit.
It had no VFO noise issue while I used it on all bands for about 2 month, in 
shack or portable.
Then it was stored in a box, in the house, nicely packaged, for about 2 month.

Today I turned it on, and it has horrible VFO noise issues.
Significantly over band noise on 14Mhz and 18Mhz, and ridiculously loud, to the 
point of making the whole experience a bad joke (could do DJ stuff with it) 
from 21Mhz up.
Without an antenna the VFO noise is clearly audible from 5Mhz up.

I am absolutely positive that for about 2 month of intense use in the summer 
there was no VFO noise whatsoever.
I have uploaded to the latest firmware but no change. I reverted to previous 
firmware but, again, no change.

How is this possible? Is this a HARDWARE problem? Some component or contact 
that degrades in time?

I know I could do the Rx Shift, but this is will disable the roofing filter.
What bothers me is that it was working fine before, and that it is not just 6m, 
but 20m and up.

Anyone have any ideas?

Cheers,

Adi M0THX

Re: [Elecraft] Small Screen for the QRP Gang

[Adi Andrei]

You could use your iPhone with iSDR or similar app.
Take either I or Q output from KX3, and connect it to the iPhone microphone 
jack.
Done it, it works. you only get 24KHz range, because the iPhone mic input is 
mono.
Total cost under $10. (4pole jack, cable)

Or you could connect both I and Q to the iPhone dock connector (stereo input) 
and get the full 48Khz

Re: [Elecraft] [KX3] digital modes ALC

Does the ALC meter  'Elecraft rule' apply to digital modes (PSK31, etc), 
meaning that 4 bars is good ?
(As opposed to trying to have no bars on ALC meter for digi modes).

Re: [Elecraft] K-3 Noise Reduction

[Adi Andrei]

For NR I always use BHI (Gap Hear it) or  Lingua 
(http://www.ssbusa.com/LINGUA.html) products. They seem to be very similar 
technology, with the audio implemented a bit differently.
If you use headphones for very weak signals in large amounts of noise, I 
recommend the 10W BHI speaker, it has a newer, quieter audio circuit, or the 
Lingua. It is impressive the amount of noise these devices eliminate without 
loosing almost any signal strength, literally things you would not hear 
otherwise in a high noise floor come out crystal clear. They pretty much 
eliminate listening fatigue in noisy environments..
Been using them for three years now in the middle of metropolitan London 
(England) with great success.
The only time I don't use them is on rare, short intervals when 40m is very 
quiet and local propagation excellent.
They are AF-type  NR using some adaptive neural net technology, and IMHO much 
better than the K3's or any other RF NR that I have seen (FT5000, ICOM and TS 
top of the line models) -  for SSB Voice that is.
Not for CW.

Cheers,

Adi

Re: [Elecraft] C9 on KIO3

[Adi Andrei]

Encouraged by Gary Surrency's feedback that I can just replace it with a normal 
capacitor, I just went ahead and did it..
In any case, I understood from Gary that RS232 wouldn't work if I messed up, 
and RS232 worked totally fine, controlling the radio from Ham Radio Deluxe. So 
all good here now.

Thanks Gary and Bill for your help,

[Elecraft] C9 on KIO3

[Adi Andrei]

Hi,

I knocked out C9, a big capacitor (compared to the other SMDs) while 
reistalling the subRX.
It got hooked by the coax from the Aux antenna.

My question is, what does C9 do, and what would happen without it ?

Also any suggestions ? I never did SMD soldering, and also this one seems 
tricky. It still hangs in its [upper] side connection, but it seems as the 
second connection is underneath it ?

Thank you.

Adi, 2E0TTX

Re: [Elecraft] UK SSB Elecraft Net

[Adi Andrei]

I agree with you on the the fact that there are nice traditions outthere, kept 
on going by true enthusiasm (rather than public money) such as Amateur Radio, 
and I wish there were more like it based on cooperation and unconditional help 
between people. We might have to rediscover or create them, because we are 
going to need them.

But you must be joking about the royals.

Many countries (including USA) had to fight bloody battles to get their 
independence (more or less successfully) from this family.
Plus there hasn't been a British king in England since the battle of Hastings, 
and William the conqueror took over.
They didn't even speak English at the court for hundreds of years after that.
This is a tradition of classism and enslavement of the many (World level) for 
the benefit of the few.

We need to discriminate between traditions.
Amateur Radio is 'noble' in a very much opposite way to royalty and empire 
building.

Cheers,

Adi

[Elecraft] Possible firmware bug - Diversity receive

[Adi Andrei]

Hi,

I think there might be a minor bug in the K3 firmware when switching antennas 
in Diversity mode.

Context:

Have 2 antennas, connected to Main and Aux, that even on the same frequency 
give you signals which are different enough that you can tell the difference.
In normal (non-diversity mode) make sure you have both receiver and 
sub-receiver antennas set to Main.
Switch to diversity mode.
Click B-Select
Set sub-receiver antenna to Aux.
Click B-Select

..so far so good, we are in diversity mode, subreceiver set to go with Aux 
antenna.

Now, suppose I want to change the NR settings on Subreceiver.

Click B-Select

ooops, I can't hear what I used to hear through the Aux antenna, for some 
reason the sub-receiver is now connected to the Main antenna (the non-diversity 
setting for the antenna).

Click B-Select

the Sub is again on Aux antenna, and everything is normal

Click B-Select

the sub is again on Main antenna

This behavior will not happen if the Sub was set to Aux antenna BEFORE going 
into Diversity mode.
So is this normal ? Or it is a bug that was not spotted before because usually 
the signals between the two antennas do not vary strongly enough to be noticed, 
and/or people set their Sub antenna before going into diversity mode.

I think intuitive operation mode would be to either have just one antenna 
setting for subreceiver regardless of being in diversity mode,
or, have the different settings, but then when in diversity mode, make sure the 
sub stays connected to the Diversity setting.

Thank you,

Adi

Re: [Elecraft] K3 filter question

[Adi Andrei]

I tested, as far as I could use my ears, but it is difficult to be sure ( 
especially being in Londodn, UK, and having S5-S9 noise on all usable bands), I 
was hoping someone has tried a similar thing, or someone at Elecraft can 
explain what is happening in such a situation in the radio.

E.g. what kind of difference should I look for ? Is it the signal itself 
altered (and how), or just the passband i.e. some frequencies missing at the 
end of the passband.
In this case, if I set the offset on .88 in  and specify the filters as having 
2.6 khz width (instead of 2.7), would then the radio behave as that was true, 
i.e. no different from the configuration I specified, although it is not the 
true configuration?
Or would it be better to leave it at 2.7 ?

In any case, thank you everyone for the answers you sent so far,

Adi

[Elecraft] K3 filter question

[Adi Andrei]

I have the 5 pole 2.7 filters for main and sub RX.
One filter offset is -.94, the other is -.81
In order to do diversity receive, I have to set them both to about -.88

My question is: what happens when you set a filter offset differently than the 
one specified (as in my case) ?
How is this supposed to  influence operation (normal as well as diversity mode) 
?
How can things be improved, short of buying new filters?

Thank you,

Adi

Re: [Elecraft] K3 receive audio

[Adi Andrei]

Also this 'feature' can be a bit inconvenient, when it happens without its 
effect being intended.
It would be nice to have the consistency and the finer granularity.

[Elecraft] small K3 firmware suggestion

[Adi Andrei]

Hi

I noticed there are 10 keys that could have macros assigned to them (M1-M4 
tap/hold  and PF1, PF2 hold), but only 8 macros in total can be assigned to 
them.
It would be nice, if that wasn't a big effort,  if 2 more macros could be 
assigned to keys.

Cheers,

Adi
