More correctly, it rejects formatted text. When you see blank emails 
with no content, that's why. I've posted to that effect several times in 
the last week.


I've used a full-featured program called Thunderbird for decades -- it 
can do formatted or un-formatted text. It's also VERY versatile in its 
ability to create mailboxes and sort based on key words (like the 
[Elecraft] in a message header, and it can handle multiple email 
addresses. It's published by Mozilla, who does  Firefox. And it's free.

Re: [Elecraft] K2 PA

[Don Wilhelm]

Aaron,

Did you replace the PA transistor thermal pads?  And if so, did you 
smooth out and metal projections on the heat sink before installing the 
heatsink?  Those are necessary steps to prevent a short from the PA 
transistor tabs (also the collector) to the heatsink.


You must always do a resistance check from the Q7 and/or Q8 collector 
leads to ground after installing the heatsink.  If that check shows you 
a zero or very low resistance, then you need to investigate the cause - 
usually metal embedded in the thermal pads, or jagged edges on the 
heatsink where the heatsink contacts the thermal pads.

I just replaced the PA's on my K2. I replaced Q7, Q8, Q11, Q13 with parts

power to a power distribution box that has a fuse for each output. This
distribution box supplies power to a small 2 meter 70cm mobile/base radio
and a LED light strip. This setup has been working with no trouble for a
while. Now as soon as I plug in the power cord to the K2 all of the power
coming from the distribution box shuts off. I used the same power cord on
two other radios and it worked just fine. So the problem lies in the K2.
While working on the K2 I messed with replacing only the parts mentioned
above. I went over the PA's with a magnifying glass looking for solder
bridges and other faults and could not find any. This problem did not exist
before I changed the PA's. I would appreciate any ideas as to what may be
the problem.

U took my Second Phone exam in 1952 when I was 16 (senior year in HS) at
the old New York Office.  Being so cocksure I never studied the stuff
for Element One (Rules and Regulations) and blew it big time because one
had to recite the "proper answer" word for word.  Came back a month
later and aced it, as well as the other two elements.   took Element
Four for the First  Phone a year later when I was 17  and a freshman in
engineering school.

The examiner in those days was the legendary Charles Finkelman, whose
name led to the "Uncle Charlie" nickname for the FCC in later years.  He
appeared formidable to us applicants, but in real life he was a really
nice guy.

In that era there were traveling FCC exam sessions (usually quarterly)
in such cities.  The "VE" system as we know it started in the mid-1980a
but if someone was more than 75 (or was it 150) miles from a quarterly
examination point, the exam for a Conditional license that had General
Class privileges could be administered by mail supervised by a
designated ham licensee.

Sometime in that era, Novice and Technician Class license exams were
shunted off to designated ham licensees as well because the FCC wanted
to try it out nationwide.  Some of the FCC examiners were happy about
that, some were not.  Hard to please everyone.

For a very short time, the FCC contracted with the US Civil Service
Commission to give written license exams at selected CSC offices but
that was never a success and did not last very long.

Re: [Elecraft] KX2 / KPA500 (resolved)

[James Bennett via Elecraft]

Let me answer a couple questions here in one message.

Jack - I recall from working with you several years ago on a similar situation 
that indeed, the amp “defaults” to 60 meters when the K3 is off.

Also, with the interrupter in place, and NO cable between K3 Key Out and amp, 
the K3 does NOT key the amp. 

So, I now have it working perfectly, as I did when I had a KX3 many moons ago. 
Here is the setup:

——> KPAK3AUX cable and Key Line Interrupter between K3 and KPA500. Two-way RCA 
jack splitter plugged into the PA Key on the KPA500; one cable to the K3 Key 
Out, the other to the KX2 Acc port (ring 2 and shield).

With this configuration, either the K3 or the KX2 can key the KPA500 and drive 
it as desired.

I see that in the KPA500 manual, Rev D, 3/10/2017, the diagram indicates “Break 
Key Line to Insert External Equipment”. Interestingly, it also shows the line 
from the amp going to the K3 Key jack, which I don’t think is correct - it 
should point to the second jack from the right - the Key Out connection, right?

Jack - do you see any problem in doing the connections as I’ve done? seems to 
work fine, and I’ve not seen any smoke escaping from either rig!

Re: [Elecraft] KX2 / KPA500

My confusion is connecting the KPA500 to both the KX2 and K3 at the same
time. I use my KPA500 with two different radios, but it is only connected
to one of them at a time. In my case it is:

RF, RS232 and PTT in from my TS-590S

I assumed that pull ups / downs when units are not powered up would mess

Re: [Elecraft] KX2 / KPA500

[Jack Brindle via Elecraft]

I went back and reread this . My question is this - with the interrupter in 
place, does the K3 still key the amplifier?

I suspect you are running into the issue of pull-ups on the K3 pulling the PTT 
signal up to Vcc. Of course Vcc when the K3 is off is 0 volts, which causes the 
KPA to key.
We see the same issue with the BAND lines, which is why the KPA500 switches to 
60 meters shortly after the K3 is powered off.

So, I’m wondering what is going on also. More details and tests should resolve 
the questions.

Jim;

Disconnect the AUX IO cable from the KPA and try it again with the KX2.
Does it have band it likes to stay on? (I’m thinking 60 meters here).

Re: [Elecraft] OT: The Colpitts mystery

[EricJ]

Any General Class ham could administer the Novice test.  The FCC field 
offices initially administered the testing, but some time in the mid-50s 
it was given over to volunteer hams. It could be anyone you could dig up 
to sign the paperwork. There were no designated VEs at the time.


I don't remember the details, but for those who could not go to an FCC 
field office for the General (disability, too far, etc.), they could get 
a waiver and get a Conditional License. That was also administered by a 
local ham, but it might have required more than one to sign off. Same 
privileges as a General Class. There might have been some limitations on 
renewals, but I don't remember them.

Yes. I've done that for years with K3 feeding KPA500 and tube amp (first 
Ten Tec 425, now 87A and KPA1500). I use relays to switch coax ins and outs.

Re: [Elecraft] OT: The Colpitts mystery

[puckrat]

I took my First Phone exam at the Seattle FCC office in the early 70's.
You had to pass the elements for the 2nd before they would administer the
first class elements. I distinctly remember a schematic of a mobile power
supply with various questions on the test I had.

The thread reminded me that a bunch of students from a local broadcast
school came in just before we started and announced that they were there
to take "the test". The proctor asked "which test?" and they immediately
went in to panic mode. After several phone calls they determined it was
the 3rd class radiotelephone.  ;-)

Are you stating that with the K2 power switch in the OFF position and

Re: [Elecraft] KX2 / KPA500

[James Bennett via Elecraft]

Hi Mark,

In one of the books I have (or had), possibly the Fred Cady KX3 book, there was 
a diagram of connecting a KX3 along with a K3 to a KPA500/KAT500. The diagram 
had a splitter in use for the key line, as I recall. And when I had my KX3 that 
was exactly what I did, and it worked fine. There is no reason, as far as I 
know, why the two cannot be connected together, provided the key line interrupt 
device is present if one is using the KPAK3AUX cable.

I looked in my parts bin and found one of those interrupters just a few minutes 
ago. I disconnected the KPAK3AUX cable and inserted the interrupter at the back 
of the KPA500, then put the KPAK3AUX cable into it. Now, when I put the KPA500 
into Operate mode, the RX level on the KX2 remains unchanged, so there was 
progress! Keying the KX2 now triggers the amp to do its thing when in Operate 
mode. I’ve got to go back and dig up my RCA splitter so I can reconnect the Key 
out line from the K3.

If Jack W6FB is monitoring this thread, perhaps he can chime in on the issue of 
having both radio’s key out lines tied together via a splitter. BTW - I NEVER 
have both powered on at the same time.

I remember in 1976 getting my novice ticket and the test was administered by 
the local club officers (same 3 guys who taught the class), but in 1977-ish  I 
had to go to the FCC field office in San Diego (the closest one to me at the 
time) to take the General tests. I guess they could give novice tests but not 
much of anything else. I was young then and really didn’t concern myself with 
the details. ;-)

Re: [Elecraft] KX2 / KPA500

[Nr4c]

First thing I’d try is to connect the KX2 directly to the amp and see what 
happens. 

Then work out your switches. 

Also, if you have tuned the KAT500 with the K3, it’s not necessary to retune 
with the KX2.   Just By-Pass it’s tuner and go. Same antenna, right - same amp.

[Elecraft] K2 PA

[Aaron K5ATG]

I just replaced the PA's on my K2. I replaced Q7, Q8, Q11, Q13 with parts
from the Elecraft PA Replacement Kit.  I have done this in the past with no
problems. Power is supplied from a switching power supply that supplies
power to a power distribution box that has a fuse for each output. This
distribution box supplies power to a small 2 meter 70cm mobile/base radio
and a LED light strip. This setup has been working with no trouble for a
while. Now as soon as I plug in the power cord to the K2 all of the power
coming from the distribution box shuts off. I used the same power cord on
two other radios and it worked just fine. So the problem lies in the K2.
While working on the K2 I messed with replacing only the parts mentioned
above. I went over the PA's with a magnifying glass looking for solder
bridges and other faults and could not find any. This problem did not exist
before I changed the PA's. I would appreciate any ideas as to what may be
the problem.

[Elecraft] KX2 / KPA500

[Andy Durbin]

"So, it seems like the amp is not sensing the RF frequency coming out of the 
KX2 - but why?"

If the KPA500 is sensing RF frequency it will display the appropriate band on 
its display.  Does it?

Loss of RX signal could be caused by failure of the KPA500 T/R switch or it 
could always be selected to TX.  Check for the keyed indicator (an asterisk on 
the left side of the KPA500 display).  It is only displayed when keyed and in 
OPER mode.

What happens if you unplug the PTT lead from the KPA500?  Does your receive
return?

Great story, Bob. I grew up in Huntington, WV, and took the exams on the 
4 times a year visits to Charleston by the examiner. It was a long 
narrow room in the basement of a federal building there, with 40 desks 
and a center aisle. A paper tape and audio oscillator sent CW. 
Applicants filed in, took the CW exam, and those who weren't in the 
first two rows filed out, because the sound echoed through the room. I 
failed there twice, finally passed it in Washington, DC in the office 
there. My folks worked for the C Ry, and were able to get me a pass on 
the mainline, which ran through Huntington to DC. I stayed overnight 
with an uncle and aunt who lived there. I was 15.


I passed the Extra and First Phone in Cincinnati at the office there 
three years later.

[Elecraft] KX2 / KPA500

[James Bennett via Elecraft]

I’ve run into an interesting situation that has me puzzled. Probably some dumb 
pilot error, but after an hour or so looking through the manuals and thinking 
about it - I gotta call in the experts.

I’ve had a K3 for ten years and the KPA500/KAT500 for maybe four or five years. 
They work great. I also have a KX2 and thought “why not hook it to the KPA500 
and give it some punch when I need it?”. Since my antenna connects through a 
coax switch between the K3 and the KX2, the output of the KX2 has been flowing 
through the KPA500/KAT500 since day one, although never being amplified. I set 
the KX2 ATU to bypass and do a “tune” on the KAT500 - finds a nice 1:1 match. 
Keying the KX2 with the amp in standby gives me 10w out on the KX2. 

Now, with a station tuned in that is say, S8 on the KX2, when I put the amp 
into operate mode, the received signal strength drops about six S-units. Going 
back to standby on the amp restores full receive strength. I have pressed the 
proper band switch on the amp. When I have the amp in operate mode and 
transmit, I get about 190 watts out, with an SWR of 1:1.

By the way - the K3 IS connected to the amp as it normally is, but powered off.

So, it seems like the amp is not sensing the RF frequency coming out of the KX2 
- but why?

I got my Novice in 1972 in Boise Idaho. I don’t remember if there was an
FCC office there. Would they have gone to other cities to administer exams,
or did they have VE’s by then? My dad and I both tested together.

The time of which I speak was in the mid-1950s. As I vaguely remember 
there was study material that prepared you to be a knowledgeable ham. 
There was also a big book that prepared you technically to be a radio 
station engineer. At a later time there was a one-day cram course to 
prepare you for the exam for first phone. Before my time if you had a 
radiotelephone certificate you had to have a certain amount of 
experience working at a commercial station in order to renew your license.

Re: [Elecraft] OT: The Colpitts mystery

[EricJ]

The FCC question pool was always published by the Government Printing 
Office. There were no answers though. All the study guides of the day 
were based on that pool including the ARRL License Manual.


Except for the Novice exam, I took General (Boston), Advanced and Extra 
(Long Beach) at FCC offices. When I took the Novice exam in 1957, my dad 
was Exec Officer for the 4th Regimental Combat Team at Fort Devens, MA. 
He found a PFC/ham within the ranks who administered the code exam. The 
PFC was shaking more than I was. I don't think he wanted to fail me. 
They were on bivouac at the time so I took it in the guy's squad tent 
sitting on his locker with a J-38 strapped to my leg. FCC field offices 
were nicer.

While I was taking the Advanced written test the phone in the room rang. The 
test administrator picked it up, listened a bit. Then a look of disgust 
appeared on his face. Then he lowered the phone, looked around the room and 
asked "HAS ANYBODY SEEN A BASH BOOK HERE?"  We all grinned back at him and 
shook our heads.He picked the phone back up said " no one has seen your Bash 
book" hung up the phone and we continued with our exams.Sent from my Verizon,

I didn’t know about Dick Bash’s “The Final Exam” series at the time, but they 
are in The Internet Archive. If you have a question about what was on the exam 
in 1981, these probably have the answer.

https://archive.org/search.php?query=final%20exam%20bash

There are other license manuals there, too, from ARRL, Ameco, and Gordon West. 
The 1933 ARRL manual is the earliest.

business. Now they just publish them themselves.

Anybody remember the Bash books?

had to wait 30 days before you could take it again. Some applicants 
tried to game the system by memorizing as many questions as they could 
when they first took the test so it would give them a leg up the next 
time. On the second attempt there were usually howls of anguish when 
they realized they were facing a different version of the test with 
different questions.

Yes there were several circuits to identify, and some to draw, as I

While in college, I co-oped with the FCC in Atlanta, GA. I had to take 
and pass my Radiotelephone First and General class licenses before I was 
allowed to administer those exams. If you did not pass a test you had to 
wait 30 days before you could take it again. Some applicants tried to 
game the system by memorizing as many questions as they could when they 
first took the test so it would give them a leg up the next time. On the 
second attempt there were usually howls of anguish when they realized 
they were facing a different version of the test with different questions.

As a 17 year old, I rode the train {pulled by a coal fired locomotive} 
from Fulton, KY to Memphis, TN.  I had to walk about 8 blocks to the 
Post Office building where the FCC administered the tests.  I took the 4 
elements and passed all 4 of them earning me a First Class Radio 
Telephone license on the first try.  I recall many much older folks 
seemingly to be struggling to take the tests.  Some commented "what's 
this kid doing in here?"  Seems some had taken it several times without 
success.     I spent the night with an old maid school teacher and 
relative in Memphis.  I took my General class license test the next 
morning in the same place.     The CW receiving portion, in the concrete 
basement with metal desks and metal chairs, sounded like marbles being 
dropped into a galvanized wash tub.   So was that a T followed by an E 
or was that and H?  Passed that one too.  Then I rode the bus from
