My Denon cassette deck slows down to about half speed when I transmit on
220 Mhz near it. No noticeable effect from 144 Mhz or 440 Mhz. This deck
is the dual capstan type with something controlling the exact phase and
speed of each capstan independently to maintain the right tension. I guess
the 220 Mhz is wiping out that function.

Jim -
By all means, jump in and make contacts! You will
be entirely welcome and will help out the "contesters."
It's a good idea to listen for a while to figure out the
exchange, but don't be afraid to just ask someone on the
air, either. By far, the largest number of QSOs made
by any hard-core contesting station are with non-contesters.
Have fun -

It might be some hidden form of preaching, but....
....it is a workable way to have VERIFYABLE text if the announcement of the
practice says what version is being used, chapter and verse.
How about some FCC rules........ every would be ham has those, right? :-)

Subject: ICOM 2-SAT repair problems
I just thought I'd share my experience attempting to get warranty
repair on my new (broken) IC-2SAT.
After sending the unit to ICOM and waiting my 10 working days quoted repair time
plus additional time required for shipment I called ICOM to see why I had not
received my radio back.
Well, it seems they have to order parts from Japan! Apparently ICOM has not
yet stocked up on parts to repair these marvelous (while working) radios.
They claim it takes 3 weeks to get parts (by boat, not plane). It is yet to
be seen whether this estimate is accurate as the 3 weeks have not yet
elapsed.
For those considering purchasing this radio, be aware that you too may be
in for a long repair time if your radio breaks.
As many of you already know, ICOM will not replace an in-warranty unit with
another until they attempt the repair, even if they have no parts, so be
patient if you need repairs.
In the meantime I'm sitting back hoping they ordered the correct part! I dread
the thought of waiting another three weeks to get additional parts.
I guess this is the danger in purchasing a new radio from any company.
Has anyone else had a similar experience?

Subject: ICOM 2-SAT repair problems
This would seem to discourage people from buying the radios the japanese
makers put out right when they do. But since there is usually such a
sudden demand when they do, they really would not be much interested in
encouraging people to buy them so suddenly. They have trouble even getting
the whole radios in supply at first.

Subject: My backyard, your backyard ...
I have read the recent flurry of comments on the issue of one's
"right" to interpret the electromagnetic energy impinging on one's property
and have some questions about what is being said:
It seemed very clear to one poster that it was improper
to make use of services transmitted over the airwaves (such as pay tv) to which
one does not subscribe.
I find it hard to understand why if I have an absolute "right"
to interpret voltages induced across my backyard aluminum that that "right" ends
just because somebody has defined their communication as something I
must pay for. In essence if I have an absolute right to demodulate
what signals I find in my backyard or living room than it seems to logically
follow that there is no such crime (and yes people have been punished for it)
as rf signal piracy, at least as far as concerns private individuals making
private and incidental use of nominally pay-for-reception information streams.
And if I do not have a fundemental right to demodulate what shows
up in my backyard, then why is it not perfectly appropriate for Congress
to define certain essentially private communications as restricted in the
same sense as pay-for-reception transmissions are ? Is there some important
difference between assuring that the provider of a signal gets his fee and
and protecting the privacy of personal communications from casual
evesdropping ?
Why, in short, should I have a right to listen to your phone calls but
not watch HBO's video ?
And the fact HBO uses DES to make it slightly harder for me
to interpret their signal (because they use DES sloppily, not because it
isn't potentially effective) should or shouldn't make a difference in whether
I can watch it ? In other words if I can break encryption, can I use the
fruits thereof - does my "absolute right" to interpret energy in my yard
extend to even those communications protected by encryption if weak
enough so it can be broken ?

Do you thin this is GOOD? If you do, I feel sorry for you.....
Just another reason for me to think that England is a police state. This may
not be ther proper forum, but then again maybe it is....I will let the readers
decide.....
England seems to have many laws that classify it as a police state: No right
of free speech, very restrictive gun laws, an oppressive "Big Brother"-type
government, high taxes.....and now I find out this: you cannot even listen
to radio waves passing through your own body!
Did you hear the recent story about how the English government gave the
environmental group Greenpeace a hard time? You may not agree with the
politics or the actions of Greenpeace, but the story tells much about how
the Police State in England operates.....
It seems that Greenpeace was trying to promote their new record album called
"Rainbow Warriors". All the procedes go to help Greenpeace fight for their
environmental concerns. Several English rock stars are on the album, and they
wanted to air commercials in England for the album.
Well, the English gov't took issue with this. Then they forced Greenpeace to
follow certain "guidelines" set up especially for the advertising of the
Greenpeace album: the ads could NOT suggest that the artists supported
Greenpeace, could NOT use the words "Greenpeace", "green", "tree", or "whale"!
The artists could not even SUGGEST that they were concerned over the state
of the environment! According to the English gov't, it was all too "political".
Now, contrast this with the SOVIET UNION, where there were NO such restrictions
set up by the government.
According to Ian Flooks, a media promoter in London who helped Greenpeace with
their legal battles, "I began to wonder who was living in the police state".
>How would Jim (or anyone else on the list) like our situation??
If you cannot tell from my above posting, I will spell it out for you:
I think it stinks! Now, you did not post what YOU think about the situation...
do you agree with it, or does it make you mad? Why don't you work to try
and change it.....but, I suspect that not enough people in England care
about the situation.

Subject: RS Discone? Good or Bad?
The RS discone is far better than the inbuilt antenna but it still not quite
enough, it seems.
I often monitor CHP in the SillyCon Valley area and find that I cannot
pick up mobiles more than a few mile away. I also have never picked up
the East COast skip that I get on the mobile in the low VHF band.
The cable is 50 feet of RG-8A/U which should not be too lossy at 50MHz and
the discone is 67 feet above ground and 3 feet above the peak of the roof.
I have one particular gripe about this antenna: the connector is a SO-239
UHF connector. It is a bad choice for UHF work. Better a N-type or BNC/TNC
type connector.

Subject: Transverters
Mark -
Transverters are great for getting on VHF one
band at a time. If totaled, however, the cost of
single-band transverters for 50-1296 MHz can exceed
the cost of a multi-band box like the FT736. But
costly or not, they will generally out-perform the
currently-available Japanese rigs because they use
a high-quality low-band rig as the IF.
Which brings me to another point. You mentioned that
you want to run the transverters from an ICOM IC-740.
ICOM makes fine low-band rigs, but (as far as I know)
they ALL have very low (<0.5 mw) output from their
"transverter" jacks. I don't know why they do this,
because no transverter on the market will run from such
a low level. You will have to either (1) dig around inside
the rig to find a higher 10-meter level to drive the transverter,
or (2) build an external amplifier to bring the 10-meter
power up to the 10-50mw needed. What a pain.

Subject: What's a good "FCC class B" PC/AT c
Whether or not the manufacturers are actually meeting the requirements of
"CLASS B", I can also tell you that CLASS B is very inadequate for use in
a hamshack.
I recommend either using tightly shielded coax (meaning Belden 9913 or 9311)
everywhere AND placing your antennas FAR FAR away, or building your own
system from those CPU motherboards you can buy (from Jameco and others)
and put it on your own real Faraday cage. If you hunt around you can even
build your own system cheaper than buying one complete.
