[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   Conditions were a little noisy, weak, with moderate QSB.  I was 
hoping for better.  Weather, on the other hand, was great all over.  I 
plan to spend the week getting my fingers dirty planting seeds and 
starts.  The birds keep me company with an occasional hummingbird eyeing 
my progress.  Garter snakes warm up in the sun and then find slugs to 
eat.  I appreciate the help.


  On 14051 kHz at 2200z:

W0CZ - Ken - ND

K6XK - Roy - IA

K4TO - Dave - KY

NO8V - John - MI


  On 7047.5 kHz at z:

KG7V - Marv - WA

K0DTJ - Brian - CA

W6JHB - Jim - CA

K6PJV - Dale - CA


   Just finished watching Virginia City.  Errol Flynn, Randolph Scott, 
and Humphrey Bogart.  They don't make movies like this any more.


   Enjoy Spring,

   Kevin.  KD5ONS

Re: [Elecraft] KPA500 failure

[Jack Brindle via Elecraft]

Don;

Does the High Voltage look about right on the display? Do you still get the 
asterisk on the display when you key down?

Give tech support a call in the morning. They will be best equipped to help you 
at this point.

[Elecraft] KPA500 failure

[Don Roberts via Elecraft]

While getting ready for the Elecraft net today my KPA500 would not transmit. In 
bypass mode swr is 1:1. When placing in operate mode I get no output with my K3 
showing high swr. Tried my loop,  vertical, and Hex beam. All show low swr on 
the K3, KAT500 and the KPA500 in bypass. 
I took the KAT out of circuit and no change. Unhooked all antennas and then 
reattached one at a time, no joy. Ran a new coax between K3, KPA500, and then 
just between the K3 and KPA500 and got the same thing.
Can run 100 watts out with K3 with low swr on all my hf antennas as long as 
KPA500 is bypassed. When I put it in operate I get no output and K3 shows high 
swr. It has been working flawless on all bands and modes. Usually run 28 to 32 
watts input for around 500 out. 
Anyone have any ideas on what might have happened. Thanks for any thoughts..

[Elecraft] K2: Unused Rev A Boards-Free to a Good Home

[Jim KO5V]

I have an unused set of three, k2 Rev A boards, left over from my second K2 
build. I did the Rev a to B upgrade to an early unbuilt kit.

If anyone can use them, let me know and I'll mail them to you. I'm trying to 
de-clutter, and I just don't want to throw them away.

Please contact me off-list.

[Elecraft] K3S misbehaving

[tazevedo]

Hello list

 

My K3S seems to be misbehaving in that the CW receive audio level starts
distorting/crackling when audio level is above about 25 percent.  The SSB
audio levels seems a bit low but no distortion with max volume.  Does anyone
out there have any ideas on what could be causing this type of problem?

 

73's

[Elecraft] KX2 not transmitting

[Ron Gould]

Selecting CW or SSB the transmitter light does not indicate transmission nor 
does it transmit when microphone or paddle attempts send dits or das.  Vox is 
enabled but does not work. Any and all help apprecieated.

Thanks and 73’s

Right. As to decoding weak stations around much, much stronger ones -- I 
face that often on 160M and 6M, which is 99.9% of my FT8 activity. My 
solution is to set the input gain to the decoder so that the strongest 
signals don't cause the A/D to clip, but raise the level of the weaker 
stations so they are above the bottom of the A/D. The indicated input 
level is then about 70 dB. Clipping is indicated by the green vertical 
bar turning red.  And I run with slow AGC.

Not quite -- there's a lot of phase shift associated with the amplitude 
response change of the notch, so it degrades docoding of signals for 
some unknown bandwidth on both sides of the notch. K1JT warns against 
using any filtering ahead of the WSJT-X decoders for this reason.

Re: [Elecraft] K3s Notch Filter

[Rick Bates (WA6NHC)]

1). The design of the K3 notch filter predates most digital modes currently 
used (excluding RTTY).   Earlier digital modes, were wider.  It may be possible 
to change the behavior.  

2). The use of legal limit or not isn’t the issue; as it may be needed to make 
the DESIRED contact, typically often required on the lower bands.  Your ability 
to hear such a strong signal has many factors, including band conditions and 
proximity. 

3). I defy anyone to determine without going to the other station or asking, if 
the ‘offending’ station is using a 10 dB amp or 10 dB gain antenna.   
Gain=gain, the means isn’t important.   Use what is needed to complete the 
contact. 

Without an amp, I would not have been able to work enough stations this past 
winter, for a 160 M DXCC (inverted L, 600 watts, 108 worked).  It would have 
been simpler has most of those I worked, also had more signal.  Full legal 
limit is very common there. 

I don’t listen to the digital modes but enjoy the quiet, volume down, ears safe 
(too late now).  I also run with AGC off, which doesn’t stop the audio system 
from using its AGC and causing blocking. 

However, FT4 and FT8 are very adept at hearing around the very strong, to hear 
the very weak.

Re: [Elecraft] K3s Notch Filter

[Bob McGraw K4TAX]

It appears from my measurements that the manual notch is about 200 Hz 
wide at the 6 dB points.  That's the width of only 2 FT-8 signals and 
the depth of the notch is about 40 dB.  Certainly will take out 1 or 2 
signals and not affect others in the 2.7 kHz BW of the normal FT-8 
receiver bandwidth.


As to the bleeding ears, turn the volume down.   I don't find it 
necessary to hear any FT-8 data.   Also, correct attention to AGC 
parameters does a lot to deal with strong signals in the midst of weaker 
signals.   Also the use of ATTN and RF Gain reduction is a big 
advantage, specially on 160M - 40M and to some extent on 20M.


As to those running "legal limit", that depends on band and conditions, 
thus one may find legal limit is necessary to make contacts.   It is a 
weak signal mode not a low power mode. {Flame shields up.}

Re: [Elecraft] K3s Notch Filter

[Richard]

Yes, I really wish the K3s could do that. I also wish it had multiple notch 
filters.

As it is, it’s so wide that you can’t help silencing a good size chunk of the 
band. Hardly practical. 

Maybe corporate feels that FT8 is just an evanescent craze that will soon go 
away, thus no need for narrower notches.

But hey! A boy can dream.

Howdy Gang.

I’ve built and owned Elecraft gear since 1999.

Still have my KX3 and KX2.

I bought a Flex 6600M rig and it was the best radio I’ve owned in years.

But Flex messed with the firmware to where if you were in full QSK mode and 
used the internal ATU a loud relay would start clicking when sending CW 
characters,  messing with the normally quiet QSK changeover from RX to TX.

The reason given for this firmware change was that when the ATU was engaged in 
full QSK mode the receive signals would be 10db down as opposed to zero db loss 
without the tuner in line.

To be honest I never noticed this problem but Flex, in all of their wisdom, 
made the disruptive change.

IMHO this firmware change completely ruined a very FB CW rig.

Perhaps the folks at Flex are not as CW-centric as the Elecraft folks.

In terms of a K4 I would certainly love to see a beautiful 8” or large front 
panel display.

This is the direction all modern radios are going….just look at the YaeCommWood 
offerings plus the Sun MB1 rig.

While the P3 and PX3 displays are OK, a full 8” or larger hi-res display is 
breathtaking and extremely useful.

So, why not a K4 with a big hi-res screen?

I’m ready for it…make it happen!!

Re: [Elecraft] XV432 deaf

[Don Wilhelm]

Raj,

I have not measured the gain of the ATF stage by itself.  That is 
difficult to do because the measurement probe can induce and pick up 
stray coupling at VHF/UHF frequencies.


I normally judged the overall performance of the XVseries transverters 
by injecting a -140 dBm signal (controlled so there is little leakage) 
with a connected receiver.  I expected the receiver response of that 
combination to show a 20 dB or greater audio signal above the receiver 
noise floor.

In other words, I used a 'system approach'.
If the overall response was not acceptable, in all cases, replacing the 
PHEMT corrected it.

I have peaked the RX cap and LNA bias.

I measured the gain across the ATF to be 10.5dB.  Does that indicate 
that the PHEMT needs to be replaced?

Raj,

Has this XV432 worked before and recently developed weak receive?  If 
so, try peaking the RX input capacitor, and if that does not correct 
it, replace the PHEMT (ATF34143).


If you recently acquired it, check the configuration jumpers for the 
28 MHz IF - do you have a single coax and it is configured for 
separate TX and RX IF (or vice-versa)?

a conversion gain of about 16 to 17dB.  The specs say 20dB.  This

to have a gain of 10.5dB.  Are these within spec?




If I can fix it without altering the circuit, that would be ideal.



Else, I am considering two mods:

Replace the MAV11 (10 to 12db gain in specs) with MAR8 (27dB gain) 
with appropriate change in the bias resistor (120 1W to 270 ohms 
1/4W)Insert a W6PQL LNA (uses PGA103+) between K10 and the ATF on

[Elecraft] software problem on K3S - software lose 2nd speaker!

[Paul Kirley]

SPKRS can switch to 1 automatically if you use mono speakers or there is 
an accidental short between the right speaker leads.  Check your speaker 
plug and wiring.


From firmware release notes:
**
MCU 3.14 / DSP 2.16, 5-9-2009

* SPEAKER PROTECTION: If you’re set up for stereo speakers
(CONFIG:SPKRS = 2), but insert a mono speaker plug, the right speaker
output will be shorted to ground. This can cause excess current drain
if you turn volume up to high levels. The K3 now detects this condition,
automatically turning off the right channel (SPKRS = 1).
*
