Frankly, I feel this isn't the forum for you to sell your wares in.

All...
I am new to this forum... this topic might not be relevant, but here goes...
Does anyone here have any interest in remote reporting radio direction
finders ? ( RDFs )
I have developed technology for that, using Doppler direction finders..
suitable mostly for VHF and above.
==============
Explaining it takes some time, but I have posted a YouTube video of a single
DF station, running in TEST mode, located at my residence in California.
( video is about 1 minute long )
https://www.youtube.com/watch?v=GdJqKNpWG5c
The DF displays on any PC's GoogleEarth screen, if a suitable PLACEMARK is
installed for it.
( not sure about smart phone versions... )
It "refreshes" once every 3 seconds, and ( in TEST mode ) the DF bearing
line ( 25 miles long ) rotates clockwise at 1 RPM.
==============
This is a YouTube recording, but the real DF station ( still running in TEST
mode ) can be viewed "in realtime" if I provide a KML link for it.
Contact me if you want to see that... I will provide more info "off forum"
about how to install and use the link in GoogleEarth.

=============
Multiple DF stations can be plotted simultaneously, on multiple displays...
yielding a plot showing the approximate location of the "hunted" station...
literally, "in seconds".
If multiple hunters ( at many different locations ) are watching the same
plot, those "far away" can ignore it... but those "nearby" can jump on it
and maybe find the hunted station.
That's the general idea... a jammer can't even "cough" without revealing
their ( general ) location.
=============
I'll provide more details for those who enquire, I prefer a phone call, (
include your number, if you please ) because e-mails are slow to compose.
This is still in an "experimental" phase, but the basic technology is all
mature and solid...
All the pieces have been individually tested, time for a complete network to
be built.... and I can't do that alone.

Greetings all,
I am sorry this is off topic but I will keep the noise low.
I have just purchased an MFJ-248 Analyzer and I wonder
if anyone would have a circuit diagram of this unit.
The has been a yellow wire cut off inside going to the top
panel I think and I am also looking for the information on
the rotary Frequency switch, I think it is a 6 position single
pole rotary but I am not sure it is a standard one.
Any info would be very welcome.
Regards ..... Peter ZL2BAU

I am very sad to hear from about the passing of Brian.
I did not had many discussion with him. But they were always courtuous and he was ready to answer any dumb question I could trow in a very polite and friendly way.
He fighted till the end. And he lived his pation about digital radio communication to the end.
My sympathie to his family, friends, and every one that he touched and helped in the hobby.
We lost a pationate mind, lets hope his legacy still live for ever.

It is with great sadness that I pass along the news that Brian Rogers N1URO
is now a silent key. He passed on Tuesday evening January 4th, 2022.
Brian was the author of the URONode packet radio software and past president
of the Eastnet Amateur Radio Network (https://www.eastnetpacket.org/). He
was an avid packet user and contributor to various software packages, not
just his own. He was also the AmprNet coordinator for the states of MA, NH,
VT, PA, MD, DE, CT, RI and ME.
Professionally his was an IT consultant and ran his company Network
Continuum Connecticut (https://www.nc-ct.net/).
He was a mentor to many who wanted to operate packet nodes or set up an
apmr.org station. He had a broad knowledge of many other node operating
systems, keeping nodes of all types running at his QTH. He was a wealth of
detailed knowledge and will be missed immensely.
Funeral arrangements are;
Friday Jan 14th
