Well drink some water from Thirlmere since it is actually a resovoir
(or was, last I knew) and if you stop by Windermere, that's my home
town. There are a couple of repeaters in that area linked to Echolink
so you might be able to communicate from Thirlmere to Thirlmere.

I don't know how hard it would be to pull this part of the software
out and run it on its own AND to control a transmitter with it.
Remember, the pmbo is probably seeing a CTS indication from the pactor
modem. You would have to use another receiver and pc running scamp
and somehow get the pmbo

Hmmm odd that. Reminds me of going to work one morning and finding that
some dummy had changed all the ZULU clock due to daylight savings time.
My windows 2000 units did NOT change time this morning.

No, it's actually trivial:
1. The PMBO's tranceiver's audio output is currently connected to the
Pactor Modem's audio input; add a connection to the soundcard input
(this might require adding a soundcard if one isn't already present
in the PC that hosts the PMBO server software)
2. The SCAMP
If I am receiving a psk31 signal at a -12 dB SNR and I can amplify the signal
by
9 dBm that would make the SNR at -3 dB. If psk31 can't decode the signal
then, I would suspect that there is a problem with psk31 or the receive or
transmit software.
A fade of 6 to 10 dB us not all that
Hi There!
Does anyone know where to get hold of one of
these chips? They got 5 leads and act as a power
switch.
They are easy to find on the net' but are
available only in bulk. Minimum order is for 250
chips or more.
I only need a couple!
If any of you find this in your neighbourhood

Regarding the comments on poor quality PSK transmissions, rather than
hoping there are observers, who on seeing such a terrible
misdemeanour as a wide overdriven transmission,who will instantly
issue a Pink Slip, why not contact the operator yourself?
In days past, if a signal was rotten
Problem is, its not yesterday. Todays generation isnt the same as what we
are used to. Ive gone so far as making a contact with the offending
station, and in the pursuit of making the QSO asked them to turn it down
while I listened and reported. Some will do so, and leave it at the
reported

There were some who were not that happy about the development attempt of
SCAMP since they had such a large investment in their modems. But the
owners wanted to come up with an alternative to the SCS modem.
SCAMP was put on hold because the programmer did not have time to
continue further
I guess for the same reason that us ham's have been passing traffic
going back to the very start of it. RTTY - CW - SSB - PACKET -
AMTOR and PACTOR. I don't see a thing wrong with a ham that
happens to be at sea (without internet or cell service) sending a
message to ever how likes.
Before one
Any kind of busy detection circuit will need to provide detection for
the entire band of frequencies you are going to be transmitting in. In
fact, this was one of my recommendations to the ARRL.
It should not be as much of a problem as you have with Pactor since the
mode will likely have one
Well seems that I hosed that message up.

Hello There,
WWV has always gone by UTC.
UTC has no Daylight Savings Time period.
They have leap seconds once in awhile.

so there !
I really don't know anything about the pmbo software. What you
describe may be trivial from a system analysis standpoint but actually
coding it may not be so easy. What you're describing is running a
second process (SBD) and making the pmbo software communicate with
that process. That may or
Don't know where to really post this but here goes. Is there a program
that will identify signals on 2m and will be able to pop up a call sign
after you have matched a particular signal to a call sign?
The PMBO server software is an an application, not an operating
system running on bare hardware. Assuming the PC hosting this
software runs Windows, Linux, or Unix, then hosting the SCAMP Busy
Detector (SBD) as an independent process would definitely be trivial.

Whoops. Yes, they do correct time for DST and standard time. My
clocks, atomic clock controlled, changed at 1 AM EDT by gaining an
hour. My UTC clock did not change - thankfully!!!

Wait! WWV and WWVB transmit UTC time codes. There is absolutely no
way for either station to 'know' in which time zone your atomic clock
is located. So How could they correct time for DST???
Enlighten me please

My atomic clock changed right on time. I would have to look at the
manual, but the clock itself may have the software for DST. However,
WWV/B would have to put out a bit that says DST for the clock to have
known to change.
My clock does have time zone settings incorporated into the software.

Savings time starts or ends at the East Coast time (think it is 2:30 AM) so
that means its 130 central, 12:30 Mountain and 11:30 in Pacific.The

Standards, there is more at Boulder than JUST WWV. This is the home

The clocks don't change, in fact the clocks don't really read UTC their
