Neat!
But be aware that it may NOT work on all radios. Well, it should work for
your Alinco model.
But some radios, like the Radio Shack HTX-242 (and I'm assuming some
of the ADI models) the 'up down' may NOT be a simple switch. If I
rememeber right, in the HTX-242 mic the ONLY funtion that is 'direct'
to the main radio body is the PTT. ALL the other functions generate
'packets' from the mic processor. Tones generate tones on the audio
line in one mode, but in the other mode they geneate 'packets' as well.
At one point I experimented with controlling my HTX-242 over the mic
input, but ran into an issue that a few key commands could only be done
by hitting buttons on the radio face... Oh well... Then my 242 got
stolen.
Somewhere around here I have all my docs on how that works...
Oh, please don't think I posted this to blast your work. I think what you
did is neat. But I just don't want someone thinking all radios work the
same way as YOUR radio, and damaging something as a result.

Last week's thread:
I learned that the serial UART rate between the D700 control
head and the radio is at 300+ KBPS... THus it wont go very far, but
someone has used it up to 150 feet away and it still worked...
Thats all I know. But its a fact.

You could always convert it to differential 'push-pull' and probably pump
another magnitude in distance over twisted wire. Parts to do that are
cheap too.

Hello all,
I am a volunteer leader for an organization called Royal Rangers
(http://royalrangers.ag.org/royal-rangers/index.cfm). Royal Rangers is a
Christian based version of the Boy Scouts. I will be taking a number of
14-17 year olds on a backpacking trip in the Cloud Peak Wilderness Area
of the Bighorn National Forest in North Central Wyoming
(http://www.fs.fed.us/r2/bighorn/). Our planned "expedition" is slated
for sometime in the two weeks after the 4th of July for 6 days/5 nights.
I will be acquiring a TH-D7A(G) within the next month (be prepared for
"newbie" questions...) and will be toting it and solar charger/extra
batteries on the trails. The TH-D7A(G) will be coupled to a Garmin Etrex
Summit. PCSat (if it is still working then) and ISS will be our primary
method of remote APRS communications. I hope to keep the parents at home
informed by:
* Using findu.com to see our position (using the topo option)
* Send short email status on our well being (blister/injury
reports...)
* Communicate an emergency situation if necessary
Three of the young men that will be on the trail with me are licensed
Amateur Radio operators. Perhaps seeing this in action will help to
further their interest in the hobby.
Wyoming APRSers, do you have any idea if there is any local 144.39
coverage on the West side of Cloud Peak? We will be starting our trek at
Coffeen Park on the Northern perimeter and ending at West Tensleep Lake
on the Southern perimeter, utilizing the Solitude trail around the West
side of Cloud Peak.
Comments and suggestions are welcome! I am particularly interested in
finding a lightweight solar battery charger and hearing about your
experiences with them (offline?). I saw one at REI, but there has to be
more out there...
Thank you!

I understand there are quite a few HOT SPRING, Mineral Baths
out Wyoming way. I am VERY interesteed to see them on a map.
Where they are in proximity to other places.
May go out Seattle way, and would like to DIVE INTO Hot Springs!
ROAD TRIP?!

I can't seem to find the recommended settings (path, time) for 10.151 APRS.
Anyone here know what to use for a home station with weather?

Well, I finally managed to copy a few packets on 145.825 during the last
pass. Still haven't seen any of my own packets, except for on findu, but I
got the following:
COMAND-1>N6CO: <<rr0>>:
COMAND-1>N6CO: <<rr3>>:
COMAND-1>N6CO: <<rr3>>:
Does that mean that N6CO was connected to the command channel?
Next question: What type of omnidirectional antenna do you find works best
for PCSat? Eggbeater, crossed dipoles, or other? My vertical seems to be
pretty useless above 45 degrees elevation.
Thanks...
Scott, N1VG

Many radios play a beep when you flip thru memory channels. Perhaps a 567
pll can decode the tone of the beep. Many of these radios (particularly
kenwoods) play a different tone when they pass by the "0" memory slot. This
could allow you to index your up/downs.

That's a thought... though I can't remember at the moment if it does that.
I know on one of my radios it does a 'beep' with every channel change, and a
'boop' when you wrap back to 1. I don't think it'll be necessary for now -
once the state is set manually it keeps track just fine. It's only got 15
memories, so if I get lost I can just flip through one at a time until I see
APRS traffic.
I'll have to tweak the chup/chdn scripts so they can display the frequency
from a list, too.
