Would someone steer me toward the modification to the Alinco DJ-180 handheld that
opens up TX on 150 MHz? I want to use this with partners business band radios.
Thanks in advance,
Ole

Hi,
I'm a total novice about electricity and electronics (despite college
physics classes), and i'm wondering if anyone knows a basic primer on
the 'net that might help me advance my knowledge. I want to know what
voltage is, and what amps are, and how they relate, and what watts
mean, and how i can understand them pragmatically. I eventually want
to build solar powered energy sytems into my house (when i get one) so
i figure it best to start learning now.
Thanks,
Mark

I don't think it's very 'proper' as it could be subject to misintepration.
I would take 'xy8 double pq' as either of the following...
xy8dpq
xy8pqpq
It really depends on how the other party understands what you're trying to
say... Why confuse 'em?

Are there any users of the CHIPSWITCH cpu upgrade for the Uniden HR2600 ?
I was tempted to buy one, but having looked at the (64pin ?) cpu that must
be removed, I was scared off. Any experiences/observations of this ??

Subject: Computer Controlled Rigs.
I am looking to upgrade to a computer controlled rig. Not knowing what's out
there I'm seeking the net's wisdom. I have a shareware
version of hyperlog that talks about a bunch of different that support
computer interfacing.
Do all rigs let you change the frequency from the computer?
Are there any radios that are easier to hookup to than others?
I'm also looking for input on cw, memory keyers and rotator control
software/hardware ....etc.... the whole 9 yards!
Thanks!

Subject: Farnsworth question
Farnsworth question
Sending "PARIS " involves the sending of 10 dits, 4 dahs, 9 spaces
bewteen marks in a character, 4 spaces between characters, and 1 space
between words. At 1 unit of time for a dit, 2 for a dah, 1 for
spaces between marks in a charater, 3 for spaces between characters,
and 7 for spaces between words, this amounts for 50 units of time per
"word". Therefore, for an exactly "5 words per minute" Morse Code
transmission, there should be 250 of these time units per minute, so
each time unit, or the length of each dit, is 240 ms. And a 13 wpm
message has 650 time units per minute, or 92.3 ms per dit.
Does a Fransworth speed of 13 wpm when giving a 5 wpm code test
mean that the dits, dahs, and spaces between marks inside a character
are set as if the test was a perfect 13 wpm test, and the other two
spaces are set as if it were a 5 wpm test? Or, should the timing of
the between letter spaces and the between word spaces be set as if
giving a 2.5 wpm test such that the overall speed is 5 wpm?
