I have a newly built XG1.
Wanted to try to calibrate the s-meter on my K2.
Problem is very weak output tone on 50 uv setting.
Not sufficient to light s-meter.
Can't hear tone at all on 1 uv setting.
All resistance checks are ok on XG1, all components look to be in correct
locations, soldering loo
Hi Rich and all,
This is an very impressive and reasonably priced project...unfortunately my
neighbors seem to like the fact that I'm qrp...but I'm thinking about it.
Only needs 6 watts to drive, too and the low pass filters are also available
quite reasonably.
Is about $60.00 a pop (poor choice
Has anyone here ever worked an OA on CW??
Ray,
Sounds like you had an interesting - and frustrating - time. Don't know if
your question is rhetorical or not but I did work OA4WW on 17 meters a
little over a year ago. I was running 10 watts to a dipole.

Can anyone point me to a site that will convert capacitor values from one
form to another. Capacitors values can be listed in uf, pf, or nf values
and converting from to another can be confusing. I recall seeing a site
that would do the conversion but I guess I have misplaced it. Help!

I use my K2/100 to drive an ALS-600 with the QSK-5 T/R box
and I can't say enough good things about the QSK-5. It's a
little pricey but it certainly does a great job and coupled with
the no-tune solid state amp its a nifty combo.
No affiliation with Ameritron, etc., etc.

Hello,
I found this pseudo number line handy

Put the 1200 in its place on the line thus:

On CW, it depends on the amp. If it is the "traditional" amp with a
relay you will have the traditional VOX delay. Or you could get an
Ameritron QSK-5 and retain the K2's level of QSK.
However if you get a QSK amp, like some of the Alpha's or TenTec's, you
can retain the degree of QSK that the

When used with the two TenTec amps as described in my post it's full
QSK (and I'm sure that the other TenTec amps will also behave that
way). The only way you know

Been following the thread on running an external amp with the K2 or K2/100.
I was wondering how connecting an external amp changes the QSK behavior. Or,
are people only using an external amp for SSB?
Thanks,

For those who think life is too short to do QRP all the time, here is what I
did. I made an amplifier similar to the amp in Communication Concepts web
page, specifically the Motorola EB-104 Amplifier (kit!) that uses 4 MRF-150
transistors.
See www.communication-concepts.com/eb104.htm. I use 48 vo

I've been using my K2/100 to drive my Ameritron AL-811H for a couple of
years, and it works great.
Initially, before I had the KPA100, I used the K2 to drive the amp to
about 200 watts or so, and built up the simple single transistor keying

I have an A model K2, so R1 was originally installed as a 51K. I removed it

where noise with AGC on and off seemed the same. I got different readings
each time I did the test, but a mid 40k reading seemed to oc
