Hi All,
In the September QST, there is an article that relates that the ARRL Board
of Directors has approved the subject plan. Details of the plan are at

operator I have a lot of problems with this plan. The lowest
James,
All those voltages look OK to me. The voltage on pin 11 is dependent on the
state of the signal at pin 6. If you wish to test it, pull pin 6 to a
negative level (jumper from pin 8 to 6) and you should see pin 11 go to 5
volts - a positive voltage on pin 6 should produce a 0 volt signal
Posting from Antoni Navarro...
I'm sad to communicate that Paulí Nuñez EA3BLQ passed away last July,
20th; being 76. As I knew he traduced the K2 manual to Spanish, and
designed a digital signal transmiter board to be used with the K2 I
wanted to make know that to the mailing list's people.
I agree with Don's analysis. Everything looks good around the MAX1406
transceiver. Since you have -9 volts or so at the output (pin 5), and
zero on the pin it feeds, there must be something amiss in between.
The small inductors are easy to break - this might be the problem, as
could be

Wonder when they will advertise the automatic logging and QSOing Contest Robot
software? Just plug it in, programming and hit the start key!!
Won't that be challenging?

I bought 8 Panasonic Oxyride AA's at Walgreenls for $10 and when my
Energizer Lithiums gave out I switched them in. These new batteries are
1.7v and are marketed as lasting longer than traditional Alkaline.
The results were not good.
They measured 1.7v with my cheap backpack DVM, and the

Hello everyone.
I have made an inquiry to have a leather case made
for my K2. I was thinking of the type used
for binoculars with a shoulder strap. This way
the rig can be taken out and put back. Plain leather
without fancy adornments though.
Or one that fits snuggly around the K2 like a glove.

There was a MountainOps nylon case at one point.
Last time I saw one on Ebay it went for more than my price range ($40 I
think). I sent mail to the OM who ran Mountain Ops and never heard if
they had any more. I have one for my 817.

I am testing the 40 meter receive and peaking filters at stage II testing. I
got the problem with the PLL licked and everything was working as
advertised. Now I cannot get any audio out of the radio. No hum, no hiss,
nothing with an antenna connected. I do get side tone and spot tone, so that
Wow you guys are good! Heh, can't believe I missed that, but then again
I build better than I diagnose! It was L2. No continuity at all. I
checked the other inductors and they are fine. I called up Elecraft and
tommorrow they will be sending a new one (or two) in the mail. Hopefully
that will
Jess,
Where and how you start depends on what test equipment you have available.
To begin, we need to know whether the problem is in the audio stages or in
the remainder of the receiver.
Do you have a 'scope available? How about an audio signal generator? Do
you have a computer with a sound
James,
Of course, we have been around this stuff for a while - that provides us
with a BIG advantage.
Glad you found it - looking forward to bigger and better things after you
get that KIO2 up and running.

You would do well to review something like the ARRL Handbook 'Component
Data' section to become familiar with the various markings used for
capacitors.
The cap marked 820 should be 82 pf, the disc ceramic marked 4.7 is 4.7pf,
the cap marked 181 is 180 pf and the one marked 182 is 1800 pf. A 47

Jess,
Make sure you have the jumpers installed in place of R18 R19 on the
bottom of the control board. These jumpers provide the path for the
output of the product detector U11 on the RF board.
If no go, check the RF board jumpers W1, W6, W5, W2 and W3 to make
sure the RF is getting to the
Finished the KPA100 and installed it in the K2 and I must say I'm
disappointed with the audio quality. It sounds like I'm overdriving the
speaker but the volume isn't near what it was with the original speaker. Is
this normal for the K2? If not, any suggestions on how to make it sound
better?
Craig,
Certainly - just in case the speaker frame is bent, take the speaker from
the QRP top cover and mount it in the KPA100 - it should sound the same -
the only difference is the wires, and wires do not add distortion.
OTOH, you are judging the sound quality with the KPA100 fully in place on
You can find many suitable cases at places selling to other markets than ham
radio.
One time, I realized a lot of QRP rigs fit the insulated coolers for six
packs. Makes a good way to store your rig in a car full time.
Larger cases with room for air to circulate would work for operational
Last night I was in Lowe's for one of my interminable shopping trips to keep
my house upright, and they had the L91's $9.89 for a 4-pack, regular price.
It's getting where an external 10-pack of L91s is getting affordable.
