Hi Alan
Memories:
14 March 1965, My first Satellite QSO.
OSCAR III went up on March 9 1965 and the battery lasted 18 days.
After two year of designing and building for this day I made my first
satellite QSO (CW)
1965 was a much different time for 2 meters and all that went along with
that frequen
Justin,
I have never heard of one of my cards being rejected, and I have helped
many to VUCC by operating portable.
Strike out your home grid, then add portable from Grid, county and state.
You should be good to go with that and you will make the card checker happy.
On LOTW I have gotte

There are plenty of commercial receiver/transmitter pairs but they all need
external filtering.
I don't know of any amateur transceivers that fall into that category.

Nigel,
Yes, of course, that's true. A single band repeater is a full duplex radio.
I don't think
I've added a lot of Alinco radios, a few HT's and a base rig. Hopefully this
is complete.
Now the fun begins. Adding the "tone/no tone" column :-). I'll probably
spend a couple hours on Universal Radio's website when school gets out
trying to find that info.

Hi Martin and other AMSAT'ers,
This is a bit beside the subject but I seemed to recall that
OSCAR-III was running full duplex in the 2 metre band:
http://www.amsat.org/amsat-new/satellites/satInfo.php?satID=26&retURL=satellites/all_oscars.php
That is not on the same frequency - but the same band.
Hi Jim and others.
For ordinary Repeaters the Rx/Tx in the same band is mandatory. But just
think of the filtering needed for TX'ing lots og watts just 600kHz away
from your Rx-frq.
This is also the reason why most repeaters (at least that I know of)
uses really big cavity-filters.
But for Rx/
Agreed, Henk, but we're talking telecommunications terminology.
Your old fashioned wired telephone does full duplex in the same band (baseband
audio) and has done so for over a hundred
years.

There will be very few radios I guess that can at the same time
receive as well as transmit on the same band / frequency ...
At least my THD7 and TS2000 can do full duplex, but not
Yes to all of the above. My cards have a portable/mobile entry field as

and work well for confirming QSOs away from home, or using as reply QSLs for
the station you worked to sign and return.
On a related note...if you w
If you are operating away from home and want to send out QSL cards, is it
acceptable to use your "home" card and note corrections to the location?
Can I just put "portable FM17" in the notes field? Should I strike
through my home grid?

Hey Patrick,
You've sold yourself and Robert a few hundred miles short with that estimate of
2,900 miles. That, of course, is the "shortest distance between Point A and
Point B" straight-line distance. But each of you had to make it up to AO-51.
At the risk of initiating a major debate here, I
Congratulations to both of you!

Not exactly.
Full Duplex can be both receive and transmit simultaneously in the same band or
on the same frequency.
Doesn't have to be in different bands.

No.
Half Duplex is when you can both receive and transmit but not simultaneously.
Full Duplex is when tou can both receive and transmit simultaneously
Simples is when you can either receive or transmit but not both.

Nice work, Andrew.
Somebody mentioned the Kenwood TS-790A/E previously (a base unit), but
I don't think I see it on your current list.
It's an important addition :)

Hi,
I have been trying to follow this confusing discussion about "Full
Duplex Radios". It seems to me that different people are using the same
term to mean different things.
Everyone seems to agree on the meaning of "Full Duplex" as the term is
used when talking about Ham satellites and radio
