low bands

[WB4JFI]

Hey Frank,
If we (AMRAD) are going to put together material for an LF Handbook, I 
suggest we need to carefully look at the existing material, and plan to do 
some major updates ad new projects.  While antenna ideas from before may 
still apply, along with some stuff like LF up/down converters, a LOT of new 
technology has come along to supplant other parts of what was done several 
years ago.

Specifically, modulation techniques, DSP, power amplifiers, preamps, etc, 
have all been improved since what was done the last time.  Unless AMRAD 
culls out old, outdated info and updates things, we run the risk of being 
laughed at for just reintroducing "old methods" that are no longer relevant 
or effective.

Hal has been talking about restarting LF within AMRAD a few times on the 
Tuesday night tech net, he was met with luke-warm response.

Separately, AMRAD members need to get on the Tuesday night tech-net at 8PM. 
There has been only 3-4 hams consistently on, and one of them keeps trying 
to sell land on hill tops instead of technical discussions.  Hal mentioned 
that he might be willing to change nights if there is a better time, but not 
everyone could make any day of the week.

I can't help with going through the file cabinet from Charleston, SC, but 
I'm willing to work on updates to LF projects and ideas.  I was also willing 
to work on Arduino frequency hopping, and had started working with Andre and 
Hal, until Andre passed away.

We had an agreement with ARRL to write an LF Handbook while the FCC was
looking at giving an LF band to the hams.  When the FCC decided to kill
that our LF Handbook effort was stopped.

I have a file cabinet of material and maybe we should contact ARRL and
restart the effort.  I would like to find someone to help with the
effort to put the book together.  It would be a great start for people
to put together an LF article to be added as part of the LF Handbook.

Do I have any volunteers?
