I use a 2 KW pure sine wave DC to AC inverter in our travel trailer.
The 60 Hz THD is less than 3% as measured.I find it works quite
nice, handles the necessary equipment including the microwave, starts
the compressor on the 5 cu. ft. refrigerator and best of all, it doesn't
cause noise
Thanks very much for the feedback from SS30DV users
I think I have good recommendation for it.
Now QRT

I have a pair of 2.7khz filters available if anyone is interested. I
just replaced them with 2.8khz filters.
Make me a reasonable offer for both.

LA3ZA used a UBLOX NEO-7 GPS unit to lock his K3.
This $20 unit including complete development board can be obtained here.

It's tiny, has a patch antenna (although a $10 active antenna works
better) and consumes under 60ma.
It can be powered from +5v or a
If higher voltages are needed to clean up the amp, how about a DC to
DC converter.
How about a higher voltage battery system rather than added complexity
in the transceiver?

Hi all,
We're looking for a few testers for the latest K3/K3S field-test firmware. This
rev fulfills a long-standing request to properly handle carriage-return (CR)
and line-feed (LF) characters in our built-in data modes, FSK-D and PSK-D. CR
and LF characters are used for screen formatting,
With bias, 12V transistors are class B or AB, not C.
See http://flarc.net/eme-info/PDF/N1JEZ-2.pdf.
He describes an amp changed to Class B (very low bias for little heating).
Regular IMD3 -22db. After predistortion -55db. Plus extra db in additional
power power. All for a cost of feedback +

Higher voltage PA and predistortion are completely separate items. Even
with predistortion, good engineering principles mean higher voltage
I have now posted a full description of my just good enough 10 MHz reference
based on the Ublox Neo-7M 12-13 USD GPS on my blog:

It has photos and schematics and shows how it affects the K3's reference

Hello everyone,
I have an extra set of pre-wound toroids for the KAT100 auto-tuner for
sale. These are from Mychael Morohovich and are of his normal very high
quality. I got them with a KAT100 kit but I prefer to wind the toroids
myself. Mychael gets $37.50 plus $8.00 for postage. I will
I have a K3 [w/ new synthesizer], an LP-Pan, M-Audio Delta, and running
NaP3v4. K3 filters are: 2.7/8p, 1.9/8p, 500/8p, 200/5p. Not sure "where"
this is happening, but decided to start here.
On CW, using the K3 CWT to center a signal, the pan display frequency
for the signal shifts around as
