it by ear enough to get it on the display... Unfortunately image signals
appear on the waterfall display too. I don't quite understand where
these come from.

Hamish, Peter has discussed this audio image business in HELP in later
versions of the program or he wrote a list posting about it - can't
remember which.

Obviously I'll have to see it to know what you mean then! :-)

Actually I have figured it out and used the MixW demo for
the CQ WW RTTY this weekend. I just click somewhere on the spectrum
to set my mark/space frequencies, then tune the radio to line up the
speaks with the markers on the screen. I don't change the tuning on
the software, only on the radio. Until you click somewhere on the spectrum
there are no markers so it is impossible to tune.

Your opinion is absurd.

In other words, don't read it if you don't already know the

garbage it is) right?

I do not know what the exact situation is in USA, but in general, the
amateur microwave allocations are on secondary basis, while the
primary user is the radiolocation (i.e. radar). In the days of fixed
frequency systems no-one wanted tho share the band with radars, but
the more frequency agile amateur systems could cope with this.
The free running magnetrons and the sharp radar pulses required quite
a lot of bandwidth in order to have a few radars coexist on a single
area on one band.
Those amateur secondary allocations are in danger, when the primary
users do not need the full bands anymore. I would be much more
worried, if no primary users could be heard. When the primary user
will loose the primary allocation, the amateur secondary allocation is
also gone.
The real value of very broad microwave allocations is that it allows
experimenting with simple gear such as free running Gunnplexers,
without the risk of running out of the band e.g. in extreme
temperatures. Apart from that, I do not see a need for more than 100
Mhz allocations on a single band, realistically speaking, we do not
have enough genuine data to move around, even if we are talking about
live video.

Subject: Kinda spooky - Bandwidth to burn . . .
Folks, all day today I tuned up and down the 7 amateur radio bands between
70 cm and 24 GHz.
It was kinda spooky, not a single station was heard!
And . . . shhhhhh don't tell anyone, but we have bandwidth to burn up
there.
Enumerated as follows . . . .
Bandwidth to burn . . .
Between 70 cm and 24 GHz, amateur radio in the USA has available 7 bands as
follows:
1.) 902 - 928 MHz 6 MHz
2.) 1240 - 1300 MHz 10 MHz
3.) 2300 - 2310 MHz 10 MHz
4.) 2390 - 2450 MHz 60 MHz
5.) 3300 - 3500 MHz 200 MHz
6.) 5650 - 5925 MHz 275 MHz
7.) 10000 - 10500 MHz 500 MHz
Total 7 bands, grand total available bandwidth 1111 MHz.
Wow . . . 1.111 GHz is ours for the taking, heck we already have it.
But . . . what are we doing with it? NOTHING.
What a great place to make broad band access networks for amateur radio for
all of those new nifty broad band applications.
Comments, thoughts?

Folks:
Is this true?
I mean with all of the new developments in cellular, pcs, lmds, etc . . .
systems is there not much more availability of inexpensive UHF and uWave
radio components?
With all of this commercial stuff going on shouldn't there be some "surplus"
stuff that we amateurs could tap into and convert to our bands, etc . . .
