Re: [Elecraft] K2 FT8

[Neil Zampella]

I've used my K2 to work WSJT-X modes for a year now, using the external
speaker audio out, and a cable connected to the mic for audio in.
They connect to a $10 USB soundcard from Amazon.The rig is connected
using the AUXBUS serial cable, to a USB adapter to the computer, which
runs DXLabs Commander.WSJT-X is has Commander set as the rig.

Works great for under $35.00, cost of audio cables, soundcard, and USB
serial adapter (FTDI chip).

Good Evening,

     I turned on the rig and found 20 meters filled with a roaring, windy 
sound.  Just a little QSB, on 40 meters it would be worse. The sun has thrown 
something at the earth.  Enough of it to cause impressive aurora.  One tiny 
sunspot can't be this strong; unless those of cycle 25 are special.  I say we 
need more of them so we can test this hypothesis.

I don't think sun spot cycle is here yet.  The observers haven't noted the 
tell-tale sign of the spots reversing polarization.  The cycles don't run a 
calendar from what I have learned and because this cycle is one of lowest in 
recorded history, possible we won't see the change from now until 2021.  Once 
the expected polarization happens then that should be the beginning.  But at

Re: [Elecraft] K3 output power failure.

[Eric Rosenberg]

W3LPL and other mentioned the PA temp and sagging power supply.

I didn't think to check the PA temp  until later (how much later, I don't
know),  If I remember correctly, it was 35C. In both cases, I was operating
in a contest (ARRL 160 and ARRL RTTY RU) with the RF power set to 100w

Sitting in front of the rig now (been powered for 15 or so minutes), the PA
is 26C.What did catch my eye was the voltage and current at the rig: 13.3v
& 1.2a in RX

I then keyed the radio, brought the power to 100w, it's a the voltage went
to 11.8v/17.9a and then shut down. The voltage went up to 13.3v/1.2a but
still no output. PA temp is 31C

I swapped power the Astron power supply for an Alinco DM-330MV switching
supply (1 ft power cable to the radio). I set the power supply so the radio
reads 14.5v. I also turned up the fan up to level 4 (it hadn't gone on
previously).. The radio read 14.5v/1.3A on RX. PA temp 22C, FP temp 30C in
RX

Still no TX output, although the radio went to 14.2v and 2.3a when I first
keyed the radio. It quickly ramps up to ~4.a and stays there until I unkey
it.

Any ideas as to what's going on?

73, Eric W3DQ

Re: [Elecraft] OT: Australian fires

[Matthew Cook]

Thanks Wayne et al,

For those that are curious about the fires here in Australia you can take a
peek at our Rural Fire Service and Country Fire Service pages...  The black
areas in all cases are fire grounds, both past (1-week) and present.

https://www.rfs.nsw.gov.au/fire-information/fires-near-me
https://apps.geohub.sa.gov.au/CFSMap/index.html
https://www.emergency.wa.gov.au/

The conditions this year across all of Australia are unprecedented, which
now includes a tropical cyclone in our states north west;

Our thoughts go out to those that seem to be under attack on all fronts and
we thank you for your kind words !

Re: [Elecraft] OT: Battery and charger recommendations for 50 watt solar panel

[W8JH]

I cannot recommend highly enough the DIY solar forum.  It to solar is what
the Elecraft forum is to ham radio, really!

The owner, Will Prowse, has a ton of youtube video's about DIY solar and has
"cookbook" type recommendations that would be stupid simple to put together.

LiFePO4 batteries are the cheapest in the long run when you consider depth
of discharge (available power) and number of cycles for the life of the
battery (buy once, cry once).

Take a look here:  https://diysolarforum.com/

And here:  https://www.mobile-solarpower.com/

Re: [Elecraft] RSP-1A as panadapter

[Drew AF2Z]

I don't use any RF protection. I carefully tested the signal levels on 
my RX loop + RSP1a on all bands and various power outputs from my 
transmitter. The separation/arrangement of my RX and TX antennas (not 
all that much) was sufficient to provide safe signal levels up to 100 
watts output. My RX antenna is a 3-ft dia "magnetic" loop with the LZ1AQ 
preamp.

Re: [Elecraft] Unable to save a Configuration on a KX3

[Jonathan Morrison]

Thank you!

After restoring the factory configuration (sent from supp...@elecraft.com)
AND sending all firmware to the KX3 -- I am now able to save configurations
again.

[Elecraft] [K4] Any Tech Data?

[Rick Miller - N1RM]

I am in the process of building a station that will use a K4, once it is
delivered.  In the mean time, I'm trying to architect the control aspects of
the station, with amplifier, antenna, and control signal routing.  Nearly
all of the public information on the K4 is marketing "brochure" info. One
thing that would really help me would be any type of high level
documentation of items for which final design decisions have been made. Even
a preliminary high level block diagram showing RF and control signal routing
and interfaces of the radio would be great.  Wayne has been incredibly
responsive to the specific questions that have been asked, but it's a little
hard to piece together the architecture from those items.

I also have one specific question: Is there a plan to have the K4 use
something like UDP broadcast on the Ethernet port to publish radio frequency
and configuration data? If so, would it be in the initial release or added
later? This approach, currently used by DxLab, N1MM+ and others, seems to be
really effective.

I know that getting the radio solid and out the door is top priority, but
keeping the customers informed (many are now actually "investors") should be
pretty close to that ;).  Hopefully there is some useful low-hanging fruit
that Elecraft wouldn't mind sharing.

Happy New Year to all,
Rick
N1RM

Re: [Elecraft] K2 FT8

[Eric J]

I used mine with a SignaLink for JT65 and JT9 several years ago. No issues. 
Shouldn't be any with FT8 either. Pulled audio from the K2 using W3FPR's 
schematic, and fed audio into the mic input. No issues that I remember. 
Remember you can't run full power in those modes unless you like replacing 
finals, and follow Don's recommendation for adjusting ALC.

Re: [Elecraft] K3 output power failure.

[Clay Autery]

Alternatively, you might (if you feel comfortable doing so) open the 
unit up and inspect it for any foreign debris that may have made its way 
into the case, thus challenging the airflow design/volume/velocity.
The PA is in its own shielded enclosure, and thus relies heavily upon 
the fans to suck air through and out of the PA enclosure and overall 
enclosure).


Additionally, I would encourage you to hook the K3 up to a dummy load 
and check to see if the fans are running properly.  Do they spin at all 
when the unit is sitting at idle (PA somewhere around 36C or so in my 
stack).  Then, set power at 100 W and Press and Hold the XMIT/UNE button 
to engage tuning ops in CW mode.  As the PA warms up, the fans should 
start to spin up as indicated by warm airflow increasing in temperature 
and velocity out of the fans on the rear panel.


_*WARNING:*_  Make sure VFO Display is showing the PA temp in the 
display and WATCH IT CLOSELY  If the fans don't start spinning up 
from slow speed by 40 or 41, tap XMIT and stop the TUNE procedure.  IF 
you forget to tap XMIT, you will put the PA into protection mode at some 
point, and MAY WELL DAMAGE THE PA, et al.


If the fans are not spinning at all, you MAY have dead fans or other 
pwr/signal issues to the fans.
IF the fans don't spin up as PA temp increases, you have issues that I 
am not qualified to help you troubleshoot properly or fix.

Eric,
Sounds like an over temperature problem.  Especially if running RTTY 
at near full power.  The high duty cycle of RTTY can cause the PA to 
get very hot.  When it gets too hot, the radio shuts the transmitter 
down for protection until it cools off in 15-30 minutes.  Too much 
audio gain/ALC can cause the same.  Review the tech manual on 
transmitter setup about over driving the K3 or external amplifier.  
Just sounds like you're driving the K3 a bit too hard for prolonged 
periods.

on the small P3 screen or on a larger display using the SVGA option.  
However, if you want to use the IF output to drive any other SDR 
equipment, there are some issues that need addressing –//

/

 * /    the output level of the IF port is about 15 to 20dB lower than
   it should be, and/
 * /    there are strong Local Oscillator signals from the K3 presented
   at the IF Out port – this is still the case if you run from the P3
   IF Out port.//
   /

/The PA K3 is a small external buffer unit that can be attached to the 
IF out port of any of the series (K3, K3S and P3).   It provides a 
filter centred on 8.215MHz and an amplifier with approx 20dB of gain, 
bringing signal back up to the correct levels. The filter uses wound 
toroidal inductors, rather than lower Q SMD inductors./

From the Technical manual for this buffer assembly:

/In normal operation of the K3/K3S, the nearest LO signals to the IF are 
when operating on Top Band (160m) -see Fig 2 below which was taken from 
a recent K3S.

/I am not smart enough in this part of things to know if this is a 
"real" concern, or "marketing" to sell a buffer/amp kit. YMMV./

If either the IF Output or the split approach with RX ANT IN and OUT 
is used, the ports are protected during transmit.   However, some of 
the SDR receivers are in plastic / unshielded boxes and themselves may 
not be adequately immune to RF.    If one is concerned, it might be 
wise to attempt to line the inside of the case with foil tape or 
enclose the receiver in a suitable metal box {the way it should have 
been in the first place}.

I used an SDR-IQ connected directly to the IF out for many years with 
no problems whatever.
