[Elecraft] APF on RTTY and TrueTTY

[Juhani Viitala]

Hi!

I have tried to solve the problem when using TrueTTY and K3s APF. 
Everything works fine without APF (using rev data) but if I turn APF on 
I lose all the tracks on the waterfall. I have tried all mark and shift 
combination. APF works ok with MMTTY but it is too clumsy program for me 
so that's why I want to use TrueTTY. MMTTY use LSB and Truetty use USB. 
I have tried to turn TrueTTY to reverse (LSB) no luck.


Any solution?

Re: [Elecraft] KPA-Anything Over 500 Watts

[Richard W. Solomon]

In my case, I piggy-backed my 220 outlets from the Electric Dryer service.
Since I don't run the Dryer and the Amp at the same time, no problem.

of AC mains wiring to support an amp safely.  The current draw on the KPA500
was at the limit of what I could do without running a new dedicated 220 line
to the operating position.  The cost of adding a new line would have been
significant, even in this house which was built in
1996 and has wiring adequate to support electric everything, including heat,
on a Colorado mountain top yet.  Hence I bought the KPA500, which I just
plug into the existing 117 sockets.  I wonder if that is the location of a
break point in the marketability curve - i.e. the point at which an amp has
for at least some potential buyers a total cost in excess of its price.

Re: [Elecraft] KPA1500

[HankP]

Elecraft already has a KPA1500 - just takes some effort on your part and some 
 Hard part is done . 

4 KPA500 factory assembled from same production lot = 4 X 2300 or $9200 

5 2 way 1.5 -54 mhz combiners capable 1 KW out (so cheap use both in and out- 
includes dump loads) - 5 X $60 or $ 300 
(RF Source - in Greece - now says 1.5 -54 ) 

1 2 way HF 1.5 54 mhz combiner capable 2 KW - make your own or same guy might 
make you one - say $200 

Few assorted cables and 4 240 v outlets 

About $10,000 and you have it . With GOBS of redundancy and gracefull 
degradation..Might be on the edge of the K3 100 watts at 2KW but 1500 should be 
OK . Combiners say 0.3 dB loss.

Re: [Elecraft] Elecraft Digest, Vol 142, Issue 38

[Greg]

How many people would it take to put $1000 or $2000 down toward a KPA1500
for Elecraft to produce it?  I would, for one.  And, I think I'm hearing
quite a few people who would be in line for one, even knowing that the amp
would be considerably more expensive than the KPA500.  It sounds like a lot
of the ground work is already done in the prototype.  Wayne had his way with
the QRP KX3...now it's Eric's turn... hi hi.  Eric or Wayne -- comment??

[Elecraft] Power Supply

[Rose]

Hi Greg!

I have the Pro Audio Engineering PAE Kx33 supply that's
been running my KX3 and PX3 24/7 for several weeks.  It
exhibits barely detectable warmth and I've not noticed any
"trash".

If you get one and expect to run both the KX3 and the PX3,
be sure to get the "splitter" addition for the output cord.

73!

[Elecraft] [K3] K3 #281 Perceived Output Issue

[Ian Kahn]

All,

I have what I think is an output issue with my K3 s/n 281. When set at 100W
output, I am getting the following approximate output values:

10m ~55w
12m ~40w
15m ~50w
17m ~60w
20m ~60w
40m ~70w
80m ~70w
160m~70w

My testing methodology involved connecting the short (~12") coax out of
ANT1 to an HF power meter's input. I then connected the power meter's
output to a 300w dummy load. I then tuned to the band to test, put the rig
in CW mode, and keyed down for a few seconds. The power meter is set to
read peak output, not average output. As a self-check, I would randomly run
the test using AFSK-A RTTY, just as a double-check to ensure I was getting
100% duty cycle. The results are the same.

After discovering these power output values, I ran the TX Gain Calibration
via the K3 utility. It ran through the 5w and 50w calibration tests
successfully. After running the TX Gain Calibration, my output power
readings didn't change significantly. My readings then are:

10m ~50w
12m ~60w
15m ~50w
17m ~60w
20m ~60w
40m ~70w
80m ~70w
160m~70w

Is there something else I should check before I plan a call back to the
Elecraft mother ship next week? If it needs to go home for repair and
testing, it will have to wait until after the Georgia QSO Party the second
weekend in April. I'm getting good signal reports when I'm on the air, but
it seems odd to me that, with the rig set for 100w out, and in a full duty
cycle mode, I'm only getting 50%-70% of my rated power.

Thank and 73,

[Elecraft] [OT] need to borrow a Mac item

[David Christ]

There have been some Mac users posting lately and perhaps one of you can help 
me out.  Please reply off list

I found an old PowerPC 8500 and several old SCSI drives in external cases that 
I want to check out before recycling.  Problem is that I already recycled all 
my video adaptors and SCSI cables.

I am looking to borrow a DA15 to DE15 HD adaptor and a short DB25 to Centronics 
50 SCSI cable.  I don’t want to buy these as I only need then for a few days.

Anyone able to help?

After checking out the units I will give them to anyone who wants them (Fat 
Chance)

If I can’t find the adaptor and cable I will crush the units for privacy 
reasons.

Re: [Elecraft] Power Supply

[EricJ]

Elecraft sells the SS-30DV for $120. Powers the KX3 and amp.

I power everything in my station with the SPS-30DM which is a voltage 
variable version with meter. Reliable, RFI quiet and fan quiet. Same 
case as the SS-30DV. Available from Powerwerx.com, one of my favorite 
vendors. A little more money.

Re: [Elecraft] [PVRC] Finding a WiFi router hardened against RF

[Fred Jensen]

I can confirm this in spades.  1,200 W to a tribander on a 70' tower 
about 100' from the TV turned the screen red when I was on 15 and had 
the antenna at about 260 [over the house].  No problems from about 300 
to 230.

Re: [Elecraft] K3s & CBLP3Y to P3 - no signal does follow VFO

[Ron D'Eau Claire]

Did you remember to connect the coax cable between IF IN on the P3 and IF
OUT on  the K3? 

If so, check that cable for opens or shorts.

Hi,

I just connected the CBLP3Y cable to the P3 & K3s. The frequency shows on
the P3 & the SVGA monitor but I see no signals on the waterfall. It was
working fine with the K3 when I disconnected it and it is now not working. 

I do have RS232 configured to USB and I have made sure the jack & plug have
mated with a click on the K3.

Ideas of what I need to do to get the waterfall working?

That's nice, but not very meaningful. Unless your amplifier is a badly 
shielded mess (unlikely) and your feedline is radiating like mad, what 
matters is proximity to ANTENNAS, and their directional patterns (that 
is, are they close to, or pointed at, the router).

"Semper Quaro" has been changed to "Semper QRO".

Re: [Elecraft] KPA1500

I realize and agree with all of what you said...  I would ONLY want to
see the piece produced if it made sense for both sides of the
equation...  I wouldn't want anything to be done that might jeopardize
the company's viability/longevity.

I want them to be here LONG after I'm gone...  Hopefully, long after my
sons have wrung the last bit of usefulness from all my Elecraft gear
that I leave behind!  :)

But I'm still pulling for them to be presented with a way to put one of
these in my hands!

Lots of possible reasons why Elecraft might not do a 1500, but specifically
price breaks and unwillingness to adopt a product that from other
manufacturers has proven problematic at our price range for well understood
reasons. Elecraft has been conservative about introductions, and that plays
well for what they *do* produce.

Ignore the boo-bird gallery on this reflector and note long term
performance of other ham manufacturers including near death brushes or full
on encounters with bankruptcy. Elecraft *grew* their business during the
great recession. Financially stable and responsive to customers with great
products. Hard to find combo, generally.

Personally I'll let 'em do whatever they want (as if I could really affect
that). They *might* put out a 1500, which I would buy in a heartbeat for
the integration. But it wouldn't be a hacksaw job and it wouldn't put their
balance sheet near the edge, and it *would* have gotten past all those
issues that 1500's seem to be dogged with.

[Elecraft] KPA1500

[Bill Breeden]

Eric, WA6HHQ, gave a presentation titled "High Performance Ham Radio: 
Inside KPA500 & Elecraft K-Line" at various hamfests in 2011, including 
Huntsville where I attended.  He explained that before Elecraft settled 
on the KPA500 they built three different sized prototype amplifiers for 
proof of concept and to establish the cost for each.  He explained that 
when that effort was complete the KPA500 was thought to be the best fit 
for the market at that time. When a member of the audience asked what 
happened to the legal limit amplifier, Eric replied that it was in his 
shack.  Eric can correct me if I have failed to remember his 
presentation accurately.

Re: [Elecraft] K3 - AFSK anomaly? No replies, try again

[Bill Breeden]

Mike,

Glad to help and glad it made sense!

When you tune across an RTTY signal using your 400 Hz filter with the 
dual passband filter turned off, first one shift, either Mark or Space 
depending on the direction you are tuning,  will enter the passband of 
the filter and then both shifts.  Assuming you have the Shift control on 
the front of the K3 centered, when the Mark and Space energy is centered 
on either side of the center of the filter (and the decoder), the RTTY 
will decode properly.  Besides seeing the decoded text, the CWT 
indicator in the meter area of the K3 display will show you when you 
have the Mark and Space energy centered for proper decode.   As you 
continue to tune same direction, you will lose the first shift you 
acquired as it passes out of the other side of the filter passband, and 
then finally you will lose the other shift as you continue to tune away.

Bill - NA5DX

Bill,

Excellent analysis and I suspect you are correct in exposing my 
current, very limited knowledge of RTTY signals. Now that I think 
about the problem, it makes sense that the radio is doing exactly what 
it is supposed to when I hear the inverted tones 170 Hz down from the 
original signal.  Rich, VE3KI, suggested turning off the dual passband 
filter to see if that has any affect, so I'll try that in the near future.

Thanks for the response and ongoing RTTY lessons!

Mark energy and the Space properly aligned in the dual passband
filter and the data conveyed by the mark and space energy is being
decoded and displayed.  In a normal "ham radio" RTTY signal the RF
energy for the Mark and Space is 170 Hz apart, with the Mark
frequency 170 Hz higher, in RF terms, than the Space frequency. 
When demodulated by a receiver operating in Lower Sideband (LSB)

mode, this results in two audio tones, with the audio tone
representing the Space energy 170 Hz higher than the audio tone
representing the Mark energy.  In the video, when your radio is
tuned to 14,091.883, the tone representing the Mark energy is
passing through the "Mark" side of the dual passband filter and
the tone representing the Space energy is passing through the
"Space" side of the dual passband filter, and the RTTY data is
decoded properly.  When you tune down to 14,091.720 in the video,
a 163 Hz difference, you have the tone representing the Space
energy passing through the "Mark" side of the dual passband filter
and the tone representing the Space energy is outside of either
portion of the dual passband filter.  There is no anomaly revealed
in your video, that's just the way that RTTY, the receiver, and
the dual passband filter works when you tune away from a properly
tuned RTTY signal.

The reason the data on the Space tone sounds like an inverted
version of the data on the Mark tone is because that is exactly
what it is.  In an RTTY signal, the same data is carried by the
both the Mark and Space energy and the state of one is the
inverted state of the other.

[Mike Murray]

Bill,

Excellent analysis and I suspect you are correct in exposing my current,
very limited knowledge of RTTY signals.  Now that I think about the
problem, it makes sense that the radio is doing exactly what it is supposed
to when I hear the inverted tones 170 Hz down from the original signal.
Rich, VE3KI, suggested turning off the dual passband filter to see if that
has any affect, so I'll try that in the near future.
Thanks for the response and ongoing RTTY lessons!

[Elecraft] KX3 Utility Terminal problem

[Tim Cook]

I set up the current KX3 Utility and connected it to my KX3 to update the
firmware and it updated with no issues. I can also use the other functions
of the KX3 Utility to change memories, set time, set banner, etc. However,
I cannot seem to get the Terminal function to work. It will decode fine, but
I can't get it to TX. I have the KX3 in the PSK-D mode but neither clicking
on TX or Crtl-T will put the KX3 into TX. I must be missing something but I
can't figure out what it might be. Any suggestions?

 

Thanks 

Tim

Re: [Elecraft] KPA1500

[j...@kk9a.com]

While a KPA-1500 or even a KPA-750 would be nice, Elecraft obviously has
their reasons for not manufacturing it. Perhaps well designed high power
SS amps are just too costly. Acom announced the 1200S last year and I have
yet to see one at a US dealer.

Reported SWR is 1.1 : 1.  This radio does not have the KAT3 in it.

Re: [Elecraft] Audio Mixer in the Ham Shack

Behringer makes lots of audio toys - and they are affordable.

Note: I no longer use them - sold/gave away all of them. With the K3 
Equlizers I no longer needed them. Not only works better/easier - makes 
the station far less cluttered. Thank you Elecraft!

Re: [Elecraft] Audio Mixer in the Ham Shack

[Joel Black]

In my continued looking and reading, I have been coming across rack-mount line 
mixers. Since all I’m really trying to do is interconnect my equipment (the TX 
and RX EQs in the K3 and KX3 seem to work fine for me) and since someone 
mentioned the Shure SCM800, would there be any “gotchas” going that route? I’d 
have to build a new cabinet with rack rails, but I have been considering 
building a new set of shelves for my amateur equipment anyway. Any other 
gotchas I need to consider?

Thanks,
Joel - W4JBB

[Elecraft] Feature request for P3TXMON

[ANDY NEHAN]

I find the P3 monitor a useful addition to my station and I believe that it 
would be even more useful if the horizontal  timebase could be extended. It has 
a current maximum of 100mS which is fine for all but slow transmission modes 
where a more extended time - perhaps 200mS or longer would be beneficial.
