Re: [digitalradio] Low signal on 2m

[Warren Moxley]

Russel,

Did you build the interface from June QST?
I am interested in doing this and am asking the Mesquite to help build one.

I am using a Icom IC-746 with a buxcom interface and FLDigi, love it.
I have never used PSK31 on 2m, but want too. My interface is designed for the 
ACC1 port for HF only.

You have to look in PART97 for stuff like that, Andy.

§97.221 Automatically controlled digital station.
(a) This rule section does not apply to an auxiliary station, a beacon station, 
a repeater station,
an earth station, a space station, or a space telecommand station.

(b) A station may be automatically controlled while transmitting a RTTY or data 
emission on the
6 m or shorter wavelength bands, and on the 28.120-28.189 MHz, 24.925-24.930 
MHz,
21.090-21.100 MHz, 18.105- 18.110 MHz, 14.0950-14.0995 MHz, 14.1005-14.112 MHz,
10.140-10.150 MHz, 7.100-7.105 MHz, or 3.585-3.600 MHz segments.

(c) A station may be automatically controlled while transmitting a RTTY or data 
emission on any
other frequency authorized for such emission types provided that:

(1) The station is responding to interrogation by a station under local or 
remote control; and

(2) No transmission from the automatically controlled station occupies a 
bandwidth of more
than 500 Hz.

[digitalradio] Try “Weak Signal” Digital FM

[Andy obrien]

A mention elsewhere of Skip's article in QST made me go back and look at it.

Try “Weak Signal” Digital FM
Here’s an application for your newly built interface that you and your friends
can try right away. All you need are ordinary 2-meter FM voice transceivers.
Tell everyone to go to www.w1hkj.com/Fldigi.html and download and
install Fldigi. This free multimode software package is available for both
Windows, MacOs and Linux operating systems. Once everyone has their
software running successfully, set up some times to meet on the air. One
suggested frequency is 145.00 MHz, simplex. (When selecting a frequency,
always follow the band plans that are in effect in your area and
listen carefully
before transmitting.)
When you’re ready, fire up Fldigi, choose either the DominoEX8 or
DominoEX4 modes and start enjoying keyboard-to-keyboard text conversations.
What you’re likely to discover is that you can span a remarkable range
with this setup, much farther than FM voice alone.
If you really want to push the envelope, use 50 W FM transceivers (or add
“brick” amplifiers to the radios you are using now) and horizontally polarized
Yagi antennas (short 3 or 4 element Yagis will do). Depending on the terrain in
your area, you may find that you can have DominoEX chats over astonishing
distances! — Skip Teller, KH6TY

I wonder if anyone has followed Skip's suggestion and tried operating
digital modes on 145.00 ?  It might be an intersting think to try,
perhaps even a simplex night periodcally where we all try a CQ and see
if anyone hears us.

Andy K3UK




Suggested frequencies for calling CQ with experimental digital modes =
3584,10147, 14074 USB on your dial plus 1000Hz on waterfall.

[digitalradio] Re: Simple PTT interface circuit ISO

[Jonathan]

Thanks for this tip.
I picked up a Tigertronics USB unit--but I will also build this one.
That's what I was looking for: something I could build and get a bit of 
hand-holding. I'm a little slow on the uptake.
