[Elecraft] Elecraft 80M SSB Net Report

[Dave New, N8SBE]

3803 kHz, 9PM ET Sunday (0100Z Monday).

Thanks to the following check ins (w) and relays (rel):

   Call   State Radio/Amp Name
1 N8SBE   MIK4D/KPA500Dave (w),(op)
2 WB9JNZ  ILFTDX101d/KPA1500  Eric (rel),(w)
3 W9PCS   WIK4D/KPA500Paul (w)
4 K8NUOHK4D/KPA1500   Carl (w)
5 K1NWRIK4D/KPA500Brian (w)
6 WN9AINK4D/KPA1500   Larry (w)
7 KD2WCY  NJK2/KXPA100Kevin (w)
8 WM6PGAK4D/KPA1500   Steve (rel),(w)
9 N3GOD   MDIC-725/ALS500 Doug (w)
10 K1DIH  CTK4D/TokyoHiPower  Brian (w)
11 KK5LD  TXK3/HB500W Dan (c/o),(w)

(Entries with (c/o) indicate a 'one and done' station that checked out 
during the 1st round)


We had a total of 11 check ins this week (including the NCS). Thanks to 
all the relays this week that helped to pull in signals that I couldn't 
hear clearly. Very nice hearing from everyone tonight. I hope to see all 
of you again. The net concluded at 09:44 PM ET.


Conditions were noisy this evening, with an S7 noise floor at my QTH, 
and signals were weaker than usual with some QSB.


We have a really great group of folks checking in, and I encourage 
anyone in the Midwest and adjoining areas to try to check in next week.


As a reminder, if you go to https://netlogger.org at the net starting 
time and look for the 80M Elecraft SSB Net, you should see the frequency 
we are using that evening, if we must QSY again due to busy frequencies.


73,

-- Dave, N8SBE

[Elecraft] Elecraft CW Net Report

[kevin]

Good Evening,

    Twenty meters had decent propagation.  At the very end the noise 
level started rising.  On forty meters there was some noise and a 
moderate level of QSB.  About two S units on everyone who checked in.  
It is surprising how well the sun is doing with the sunspot number so low.


    Seventy degree temperatures have melted more of the snow.  In 
another few days it will be gone at my elevation.  The birds are already 
taking advantage of the newly hatched insects.




  On 14050.5 kHz at z:

W0CZ - Ken - ND

K0DTJ - Brian - CA

K4JPN - Steve - GA

WJ7S - John - UT

K6XK - Roy - IA

W8OV - Dave - TX


  On 7047.5 kHz at 2200z:

K0DTJ - Brian - CA

K6PJV - Dale - CA

WM5F - Dwight - ID

W0CZ - Ken - ND


Until next week 73,

   Kevin.  KD5ONS


Happy Saint Patrick's Day !!

[Elecraft] Elecraft 80M SSB Net Announcement

[Dave New, N8SBE]

Please join us on 3803kHz (NOTE THE NEW FREQUENCY) plus (not minus) QRM 
(see the Netlogger discussion, below), 9PM ET Sunday (0100Z Monday). 
Note that the net stays on the same local time, when we switch back and 
forth to/from Daylight time, so the UTC time changes, but not the local 
time.


As daylight persists more into the evening, we may find it more 
difficult to conduct the net at its regular time.  For the time being, 
let's keep it at 9PM ET, as that is getting late on a 'school night' for 
a lot of folks, as it is.


Your net control this week will be Dave, N8SBE.

The group that meets on 3803 kHz before us has been wrapping up 
operations promptly at or before 9PM ET.  They are aware of our net that 
follows them at 9PM ET, and have made an effort to accommodate us, and 
sometimes one or more of them listen in on our net, so I've made a point 
of thanking them for their courtesy.  Likewise, I've become aware that 
another group normally comes on at 10PM ET, so we need to make sure to 
wrap up operations by 10PM ET.  If any stations wish to continue past 
that time, please QSY to a clear frequency.


If you are a US General class licensee, please ensure that your dial is 
accurately calibrated and that your transmitter/amplifier combination is 
clean and free of splatter, since we will be operating LSB within 3 kHz 
of the lower 80M US General class band edge.


I'm using Netlogger, so if you go to netlogger.org and look for the 80M 
Elecraft SSB Net, you will be able to see the exact frequency we've 
settled on for the evening.  If we find 3803 kHz busy, we will move UP 
the band a few kHz, so we can stay in the 80M US General class band.


Hope to see you this evening on the net.

73,

-- Dave, N8SBE

Re: [Elecraft] K2/100 down power on 20M

[Michael Carter via Elecraft]

Hi Jerry,

I agree that the relatively low TX power output on 20M
originates in the KPA100 module.  Did you build that
module and install it yourself?  The LPA circuit in the
base K2 seems to operating normally, and your
peaking of the BPF confirms that.

If you have capability to sweep the 20M/30M LPF
section on the KPA100 for insertion loss, that would
provide more insight.  However, those LPF sections
are also inline when the KPA100 is nominally
bypassed - it's only the amplifier circuit that is
bypassed.  If there was a significant problem in the
LPF on the KPA100, it would have been evident in
your tests on the 10 watt TX power setting.

I would check the ALC indication on each band, but
set the Power control for 100 watts rather than full
clockwise rotation.  You could also monitor the
ALC voltage on the Control board as you change
bands to see if for some reason the ALC control
is reducing TX power on 20 meters.  There is no
band-dependent circuitry in the ALC system,
but the SWR forward/reverse power detection
circuit on the KPA100 does have a trimmer cap
to balance the bridge.  It would be unlikely for
a resonance condition in the bridge to cause
an elevated VRFDET voltage on one band alone,
but I am curious if the ALC system is doing something
odd on 20 meters only.

73,
Mike, K8CN

[Elecraft] [K3} High SWR on 17 meters

[Dave KØEKL]

I attempted to do the TX gain calibration on my K3, S/N 1171 today but it fails 
with 2.2:1 SWR in 18 MHz.

I've tried both ANT1 and ANT ports on the K3, multiple different patch cables, 
and two different high-precision Cablewave dummy loads. With my LP-100A SWR 
meter in-line when testing it shows 1.02:1 while the K3 and the K3 utility say 
the SWR is 2.4:1.

What should ZI look at next?

Have no idea what it is worth.

If anyone wants it, please make me an offer. THANKS 

Best offer gets it. Thanks for helping me with the estate sales. The family
involved appreciates it.
