[Elecraft] Elecraft CW Net Report

[kevin]

Good Evening,

   Good conditions were not to be found.  Both twenty and forty meters 
had moderate to high noise levels with all manner of QSB. The strongest 
signal on twenty was from RI.  Forty meters is changing noticeably from 
week to week.  The strongest signal there was from ID, my next door 
neighbor :)  We had to move the forty meter net.  They could hear none 
of us.  Hopefully I did not miss you in the noise.  Summer storms and 
space noise hit S4 at times. Since I don't really have any local noise 
this is high for me.



  On 14050.5 kHz at 2200z:

W0CZ - Ken  - ND

K6XK - Roy - IA

K1NW - Brian - RI


  On 7047.5 and 7047.64 kHz at z:

W0CZ - Ken - ND

K7TXA - Jim - ID

K0DTJ - Brian - CA


Cool weather is returning with clouds coming in from the Pacific.  
Hopefully that will bring some much needed moisture.  It would be nice 
if a band of it would sweep east for the next week. It is too dry.



Until next week 73,

   Kevin.  KD5ONS

Re: [Elecraft] Sunday evening 80M Elecraft SSB Net

[John Paul Keon]

I will try to make it next week.
I have a QRP net (CW) every Sunday night at 9pm local and will
try to jump over there and say hello if I can make it.

Yes, FANticipator works great, but my point is if Elecraft would allow us to 
use the 6m fan profile on HF, we wouldn't have to turn on our intrusive 
computers at all to communicate in the sublime world of QRO CW.

My apologies to Larry for my error.  He is of course correct about 
FANticipator's connections, he wrote the software and does a great job 
supporting it.  For free.
FANticipator keeps more than 100 KPA1500s cooler and quieter, if the numbers on 
Larry's dist list are mostly FANticipator users like me.
Interestingly, people have contacted me with the drastic measures they have 
taken to quiet their KPA1500s, but none have gone on record supporting my 
swtchable fan profile suggestion. Therefore, given Elecraft''s huge workload 
these days, it will most likely never make "The List."

FANticipator does not require WiFi, merely a computer on the LAN - ethernet or 
WiFi.  The only additional connection is ethernet to the KPA1500.

Re: [Elecraft] K3 INTERFACE WITH LDG Z100A

[N4ST - Jim]

I have tried to find a way to interface a K3S with an LDG-200.
It needs a digital to analog conversion interface since the LDG uses discrete 
voltage levels as inputs for the proper band.  I don't know if the Z100A uses 
the same analog signaling.
In the mean time, I wrote a macro to drop my K3S to 20Watts, do a TUNE, wait 2 
seconds and then cancel the TUNE and bump the power back up to 70W for digital 
work.
A one-click mouse solution for using the LDG memory auto-tune.

Subject: [Elecraft] K3 INTERFACE WITH LDG Z100A

I purchased a Z100A with the idea of interfacing it to a specific brand/model 
of radio.  I investigated the Z100A requirements to initiate the control of the 
tuner via the transceiver.   From my earlier work, I don't see there is a 
command from the K3 that will support the requirements of the Z100A.  However, 
there are many ICOM radios that do have the provision.  Thus the command comes 
from the radio.

 From the LDG manual:

"The LDG Z-100A includes the IC-104 DC power cable, as well as a three 
foot IC-100 Icom interface cable. However, interface cables for a 
plethora of other radios are available as an optional purchase, 
definitively making the Z-100A the last tuner you'll ever need to purchase.

Press "Tune" on Tuner - Keys Automatically

  * IC-105 Alinco interface cable - uses EDX-2 jack, DX-70 and DX-77
  * IC-108 Yaesu interface cable - uses TUN/LIN and KEY jacks, FT-891,
991/A, 857, 897, 100
  * IC-109 Yaesu interface cable - uses TUN/LIN jack, FT-DX10, 1200,
FT-950, 450 (NOTE: Do not select external tuner in settings)
  * IC-115 Yaesu interface cable - uses LINEAR jack, FT-DX101D, 3000
  * IC-106 Kenwood interface cable - uses AT-300 jack
  * IC-105 Alinco interface cable - SR8T, SR9T"
  * Compatible with any Icom radio that is AH-4 or AH-3 compatible. (6M
tuning from Tuner button for radios that are only AH-3 compatible)
  * Partial radio list: IC-706, 703, 718, 7000, 7100, 7200, 7300, 7410,
746, 756, 7600, 7610 (and all variants).

I find nothing to indicate the LDG100Z will interface with the K3.  In 
reviewing the signals on the ACC connector on the K3, I do not find one 
dedicated to the TUNE function. See page 20 in the manual, ACC(Accessory I/O)

I have tried to find a cable that goes from my K3 to the LDG Z100A tuner but 
all I see is just a cable with a Molex like connector going to the tuner and 
nothing on the other end of the K3 except bare wires (i.e. no connector). Does 
the tuner have to get connected to the K3 ACC jack?? Or does someone have a 
wiring diagram so I can marry the correct connections between the 2 units?

[Elecraft] KPA500 No Output on 6m

[Andy Durbin]

Is the KPA500 being keyed on 6 m? (Does the asterisk appear in the KPA500 
display?)

Some rigs, such as the Kenwood TS-590, require the keying output to be 
specified separately for 6 m than for the HF bands.

Re: [Elecraft] KPA500 No Output on 6m

[Jim Clymer]

Hi Dave,
More information would be helpful. Are you seeing your radio's output thru
the KPA500 (and on the meters) with the amp in bypass mode? Is the radio's
PTT properly keying the amp? Etc.

[Elecraft] K3 INTERFACE WITH LDG Z100A

[Bob McGraw]

I purchased a Z100A with the idea of interfacing it to a specific brand/model 
of radio.  I investigated the Z100A requirements to initiate the control of the 
tuner via the transceiver.   From my earlier work, I don't see there is a 
command from the K3 that will support the requirements of the Z100A.  However, 
there are many ICOM radios that do have the provision.  Thus the command comes 
from the radio.

From the LDG manual:

"The LDG Z-100A includes the IC-104 DC power cable, as well as a three 
foot IC-100 Icom interface cable. However, interface cables for a 
plethora of other radios are available as an optional purchase, 
definitively making the Z-100A the last tuner you'll ever need to purchase.


Press "Tune" on Tuner - Keys Automatically

 * IC-105 Alinco interface cable - uses EDX-2 jack, DX-70 and DX-77
 * IC-108 Yaesu interface cable - uses TUN/LIN and KEY jacks, FT-891,
   991/A, 857, 897, 100
 * IC-109 Yaesu interface cable - uses TUN/LIN jack, FT-DX10, 1200,
   FT-950, 450 (NOTE: Do not select external tuner in settings)
 * IC-115 Yaesu interface cable - uses LINEAR jack, FT-DX101D, 3000
 * IC-106 Kenwood interface cable - uses AT-300 jack
 * IC-105 Alinco interface cable - SR8T, SR9T"
 * Compatible with any Icom radio that is AH-4 or AH-3 compatible. (6M
   tuning from Tuner button for radios that are only AH-3 compatible)
 * Partial radio list: IC-706, 703, 718, 7000, 7100, 7200, 7300, 7410,
   746, 756, 7600, 7610 (and all variants).

I find nothing to indicate the LDG100Z will interface with the K3.  In 
reviewing the signals on the ACC connector on the K3, I do not find one 
dedicated to the TUNE function. See page 20 in the manual, ACC(Accessory I/O)

Content-Type: text/plain;   charset="UTF-8"

I have tried to find a cable that goes from my K3 to the LDG Z100A tuner but 
all I see is just a cable with a Molex like connector going to the tuner and 
nothing on the other end of the K3 except bare wires (i.e. no connector). Does 
the tuner have to get connected to the K3 ACC jack?? Or does someone have a 
wiring diagram so I can marry the correct connections between the 2 units?

 


73?s,

Greg N9GB

[Elecraft] KPA500 No Output on 6m

[dave ingebright]

Bought and assembled a KPA500 kit in 2018. No output on 6m!! I've used it on 
10-80 and love the performance. Never checked six until I became interested in 
six this summer. Put up a 3 ele yagi and its good barefoot/good match but no 
output on six using the KPA...
Any ideas? Here's a link to my assembly picts:

Re: [Elecraft] RFE KPA1500 Fan Protocol

[eric norris via Elecraft]

My apologies to Larry for my error.  He is of course correct about 
FANticipator's connections, he wrote the software and does a great job 
supporting it.  For free.
FANticipator keeps more than 100 KPA1500s cooler and quieter, if the numbers on 
Larry's dist list are mostly FANticipator users like me.
Interestingly, people have contacted me with the drastic measures they have 
taken to quiet their KPA1500s, but none have gone on record supporting my 
swtchable fan profile suggestion. Therefore, given Elecraft''s huge workload 
these days, it will most likely never make "The List."

FANticipator does not require WiFi, merely a computer on the LAN -
ethernet or WiFi.  The only additional connection is ethernet to the
KPA1500.

3. Power amplifier's current.  Making sure it's below safe level.
-
4. Power amplifier's output power at the amp not somewhere on the coax cable.
-
5. SWR that the amp sees at its output of the amp not somewhere on the coax 
line.
-
6. Displays Operate/Standby mode.  Keep a check on mode so you don't key the 
amp unexpectedly.
-
7. Displays Band amp is tuned to, making sure amp and radio are on the same
