Here is the list of stations checking in to the Sunday net for 9-26-2021. Thank 
you to the relay stations who always help pick up additional stations not heard 
by net control. 

SSB Nets on Sundays: We welcome everyone regardless of the type of radio they 
are using. Hope to see you on one or more nets.

Re: [Elecraft] PX3 kit tips?

[Julia Tuttle]

Hi folks,

My PX3 is up and running! The manual was a delight to follow, and
everything went together swimmingly. Thanks for all the tips -- I had
everything small neatly laid out in an egg carton, and assembling this was
probably the most peaceful hour of my day.

Here is a lousy phone picture of the finished product:
https://photos.app.goo.gl/NsXTLNo2zZPcuM4p9

One question: I performed the sideband nulling procedure, and found that my
ideal phase values were similar to the factory ones, but that my ideal
amplitude values were consistently about 25 lower than the factory ones. Is
this indicative of an issue with my equipment, build, or calibration? Or is
it within the expected range of calibration values?

Thanks and 73,

Julie

[Elecraft] KPA-1500 problem

[RVZ via Elecraft]

Hi Guys,
 My KPA-1500 is having an issue: with the internal ATU tuned "OFF" or in 
"ByPass" mode, when transmitting the KPA-1500's relays occassionally chatter 
like a machine gun while transmitting.  It sounds just like the relays do when 
the ATU is turned "ON" and it's tuning an antenna for minimum SWR.  Are there 
any KPA-1500 configuration settings that could cause this to occur even though 
the ATU is turned "OFF"?  Any ideas why this is happening? Thanks!  Dick- K9OM

Yes, it's audio rectification, but I'll go to the mat about "front end 
overload" NOT being a primary cause of RFI (and I went to the mat with 
ARRL ten years ago and lost). Rather it's "the Pin One Problem," first 
noticed in the world of pro audio by a ham, the late Neil Muncy, 
ex-W3WJE. That's the failure to terminate cable shields to the shielding 
enclosure at the point of entry. EVERY rig I examined the last time I 
was at Dayton had Pin One Problems at their accessory connections. 
Nearly all computers, computer accessories, and consumer equipment has 
this manufacturing defect.


This is why proper bonding in our stations and ferrite chokes on wiring 
connected to victim equipment solve RFI problems.

Re: [Elecraft] KAT500 - does it earth antenna connections

[Andy Durbin]

"You don't need to manually choose an antenna on startup. It remembers what
was last used on each band (assuming you are using an Elecraft or Kenwood
rig with it). I think it will still remember the last used even in a dumb
situation without knowledge from the radio; it just needs the radio support
to have "per-band" memory."

No radio support is needed for antenna per-band memory.  All the KAT500 needs 
to know is the TX frequency.  It then decides which antenna to select based on 
"band" and the antenna preferences defined by the KAT500 PC Utility.

A weakness of this design is that, if only RF sensing is used for frequency 
determination, the KAT500 may fault due to a mismatched load before the 
appropriate antenna has been selected for the new band.

Antenna selection can be performed by serial command but, even though my 
controller is capable of that, I have seen no reason to replicate the antenna 
selection logic already built into the KAT500.   There is a caveat though -  
the internal antenna selection logic doesn't work correctly when KAT500 is in 
BYP mode.  (The workaround for that defect is to never use BYP mode.  MAN mode 
with Byp active is electrically the same and antenna selection does work 
correctly in that configuration).

73,
Andy, k3wyc

Re: [Elecraft] PX3 kit tips?

[Geert Jan de Groot]

Just follow the instructions.? You will need a #1 Phillips screwdriver.


Are you sure that's Phillips? I use Pozidriv (PZ0) for Elecraft screws 
and find that is a much better fit.


(Either will work, but if you have one of those 100+ screw sets and have 
the choice - consider PZ over PH screwdrivers for electronics)


Yours for screws that are not stripped,

[Elecraft] Last round of K3 upgrades

[Pete Smith N4ZR]

It's been more than a month since Elecraft's "last call" for these 
updates, but I haven't seen anything to suggest when they might be 
available. Anything from on high?

Re: [Elecraft] KAT500 - does it earth antenna connections

[David Aslin G3WGN]

So if I have one antenna port which no longer seems to function (port 2) the 
GDT may be a good suspect?
Suggestions for troubleshooting invited

[Elecraft] KAT500 - does it earth antenna connections

[Bob McGraw]

I would suggest a dummy load be connected to antenna port #1 and your 
antennas to #2 and #3.   As to grounding, I suggest one review the ARRL 
book "Grounding and Bonding for the amateur station".


I've seen many ham stations that ground ground ground and still have 
issues, in some cases they attribute to a dangerous condition,  
regarding lightning protection and RF grounding. There is a LOT of 
incorrect and incomplete information passed around with regard to 
grounding.  It is mostly originated as  "old ham lore" with no 
scientific basis found or applied.


And yes, the KAT500 has 3 antenna ports and port #1 is the default 
selected when power is not applied.

Interesting idea.
I have two antennas, so I could connect my ground to #1 and antennas to #2
and #3?
Just manually choose an antenna on start-up.   Hm-m-m-m-m.

Re: [Elecraft] PX3 kit tips?

[Jim Finan]

Do a complete inventory of all parts before you begin. It isn’t unusual for a 
small piece or two to go astray.

Simply call Elecraft and they’ll send it to you. Though it may be a little 
slower than in the past with the challenges of late.

Most important- have fun!
