Subject: Silent Beverages
Frank, W3LPL in his excellent posting on phased Beverages shows convincingly
that we should use 80m for 3.5-4 MHz band. I only wish he used meters for his
recommended Beverage lenghts as I always assumed they should be multiple of
wavelength. However, 580 feet comes to about 175 meters which is littlebit
longer than full wavelength. What generates "cone of silence" for this exact
antenna length? I remember visiting famous UK reception site long time ago
and they were using very long Beverages as they needed to hear "what the BY's
had to say to UA's" in their own cold war words! The lowest HF BC band was
around 5 MHz but when you think of it, there was not much QRM from the back!

Subject: European jaunt - September
Hello all: Will be in Europe 3-15 Sept. and would very much enjoy meeting
any DXers, contesters who might in the cities in which I will be stopping....
I'll be in (DL) Frankfurt, Bamberg, then to (HB), Forcheim, Wannbach
and Muggendorf...(Back to DL) Kulmbach, Bayreuth. The on to (OK),
Plze and Prague. Then back to Frankfurt.
Although primarily a business trip, I plan to have a good amount of time to
indulge my real interests, hi....
Please drop me e-mail if you might be available for a chat. I'll then send
along the dates and hotels for these assorted stops.

Frequency happens to be one of the easiest things to measure.
The ARRL lab has quite an investment in power measuring gear--the
stuff isn't cheap. Such a meter would be great--you could replace
all those expensive Bird slugs with a receiver and a bunch of calibrated
There a bunch of variables involved. Usually, you use a log amplifier,
which is highly temperature sensitive unless properly compensated.
Putting all your circuitry in a temperature controlled oven would help
a great deal, if you didn't mind the warmup time. There used to be a
problem of getting a flat frequency response out of the filters, but this
can be fixed by using lookup tables and having the computer make
the necessary adjustments.... Of course, once you have come this
far, you might as well have the equipment test itself... I think the
market is too cost competitive to pay for what it costs...
Maybe in another 10 years computer software/hardware technology
will be developed to the point where the computer can calculate how
the circuits will perform based on previous/present enviromental
conditions....allowing the real time calculation of correction factors....
Its certainly not here now...
The readout isn't a problem, computers can be programmed to display
any unit you want.

I think that this is my favorite contest even if the conditions aren't the

a statement about AL weather although that was the most obvious
interpretation (I did think about using HOT a ways through the contest). The
name was my dog's. We decided to use the contest to remember her since she
died on Friday. Rest in peace Sunshine.

Subject: New Radios
Regarding general coverage tradeoffs...keeping an external bandpass filter
in the line (such as the DuneStar or ICE units) would certainly help keep
strong out-of-band signals from clobbering the front end. As these can be
controlled by the radio band-output information, it would be automatic. A
bit of a reverse solution (add gc coverage, then take it back out), but

Please help me understand this. With virtual memory I can run programs
much larger than the physical RAM, yet don't have a performance hit?
Pray tell, where is the code if it is not in swap space on the disk?
And if it is on disk, the access time is mesured in milliseconds, not
microseconds. Seem to me there will be a performance hit. Must be a reason
WinDog and the other operating system all want BIG physical memory.

Subject: DSP power
You can implement a true and "perfect" phase type SSB transceiver if the
IF is done in DSP. Image problems are greatly minimized. Filters can be
"perfect" in that they can be zero phase (no frequency dependent group delay)
and filters with extremely sharp shape factors can be implemented that you
simply could not afford in analog filter components. The dynamic range of
most modern DSP chips is more than adequate with extremely large word
sizes and huge accumulators and now with CD technology giving is very wide
dynamic range A/D and D/A chips, there is no reason not to try for this stuff.
You could implement modems for all HF modes so long as an intelligent host
interface is also provided. All of this will only take take a forward looking
manufacturer who believes it will make money.
