Thank you for a most complete answer. I will take your advice on several if
not all accounts where possible.

I would like to take the time to congradulate the fellows who forced W3OK
the Delawarre Lehigh ARCs Field Day station off of 14.233. Your
effective and relentless sending of SSTV transmissions which aparently
were unidentified by SSB or CW was completely effective. Without a DSP
filter I was completely unable to keep my frequency. So I must
congradulate you and will of course return QSL upon reciept of yours.
Oh yes if you get a moment would you explain to me how a picture of a
girl in a swimsuit will help durring an actual emergency? Somehow I was
unable to explain this to anyone from the Plainfield fire Co. whos
facilitys we were using.
Hey I have an idea rather than spend all that money on gear used to swap
R rated gifs over the air if you promise to let me use your frequency
next year for say just half the time I will give you 24 hours of time on
my LL BBS and you can suck the adult CD ROMs dry! Just think what fun
you can have then!!
Again congradulations

I had the same type recepton on Saturday. I came upon 14231.5 which was
free. I asked my usual 3 times is the frequency in use and received no
response. After my second CQ someone who id'ed only as DW came down told
me that I was tearing up both 14230 and 14233. Not sure how he was able
to be on both but that was his statement. When I said I was a kc and a
half off both of them he stated that did ot matter. The freqs belong to
SSTV and would not be used for FD. Of couse I did not buckle but then was
bombarded with SSTV, which was intentional. My goals in FD was to make
contacts so I did leave the area. Everytime I went by these areas I
checked and it seemed that same thing was going on.
The week prior to FD I found two hams sending SSTV on 14218. When
questioned why they where there I was told that SSTV would go anywhere
they wanted. The calls of these staions were VE3JDJ and N4OBQ. They
announce another sked for the next day.
I also hear them make the comment this weekend that you could blame the
ARRL for what happened this weekend with the contest. FD is one of the
best promoters of ham radio there is. On local TV and in the newspapers
have been article concerning FD all weekend. I have never seen anything
to do with SSTV in the paper. I see no purpose that SSTV serves execpt a
toy for dirty old men.
I am not sure what can be done about this but something has to be done.
Without a doubt they are a very small minortiy in ham radio and should
not generate all these problem. I believe the deal with FD should be that
last straw.

Anyone up for a all SSTV contest? We could exchange pictures of serial
numbers and signal reports.

Lots of good ideas to consider: among the best were these ...
Use a VHF handie to check it out there at the store ...
Read the ARRL Interference Book ... Lots of FB info from Ed Hare
INSIST ON BEING ABLE TO RETURN IT IF YOU HAVE RFI PROBLEMS ...
Now the search begins !

(PS ... Didn't get a 87-a, but SHE got NEW LIVING ROOM "stuff" ... alas)
Here's the summary of responses
*****************************************************************************
We bought a big screen Panasonic tv this year--like 30 inches or so and
about the same time a Panasonic vcr, 4 head. Don't have the models handy
right now, but then it hardly matters-they change monthly. Anyway, the
Panasonic vcr is housed in a metal cabinet as opposed to those plastic
rfi traps. I added a seperate wire to the cabinet to go to ground and hve
never had a problem. Good luck, my wife thinks radio is dumb until a
RACES alert comes on the 2 meter, and then she gets religion.
******************************************************************************
Just a word or two that might help. I had a severe problem here with one
TV/VCR combo in my sons room, both RCA. My 2-M packet stations tore it to
shreds. I called ED HARE at ARRL Hq, TECH DEPT. He is the closest thing to
an expert in this field that I know of. He had some excellent
suggestions, which my son and I tried. Finally discovered that it was
the VCR itself (about 5 years old). To make a long story shorter, Ed gave me
some tips on what to ask for when we went to buy a new VCR. Using his tips,
we were able to buy a VCR that has absolutely NO problem whatsoever,
even with the original RCA TV. I recommend that you call ARRL and ask for
Ed and tell him what you are after and ask for suggestions. He will not make
specific brand or model recommendations - ethics or something like that - but
he can tell you what questions to ask of the sales people.
*****************************************************************************
I just purchased a "Proscan" Tv/VCR-made by RCA/Toshiba and it seems pretty
solid from RFI(on cable)-great picture as well!!
*****************************************************************************
For what it's worth, I've had a TEAC MV-625 since Christmas of 1992. I'm
active on 160M thru 1296, 1500W thru 10M & Bricks on VHF& UHF. I use with
an old 13 year old Sharp TV & cheapie Radio Shack TV antenna and the only
interference I get is on channel 2 when I point the 6M & 100W right at the
antenna. No tower is more than 100' from the Antenna or Set. No precautions
or filters used on either the Amateur gear or TV/Stereo. Also, I have the
sound piped thru a Realistic (Radio Shack) 100W Tuner. NO interference at
all.
Don't know if they make it any more or not; it's a no frills device, but
does have a remote, does everything I need, the XYL loves it & if I remember
it was in the high $200 price class. It has been a very reliable piece of
equipment.
******************************************************************************
I've had good luck with one cheap, and one mid-priced Magnavox (Philips)
VCR. (I can look up the model numbers, if you're interested.) They
were both RFI free within 50 feet of my antennas, with nothing more than
a cheap High Pass filter and some ferrite cores on the coax and power cord.
Alas, in the same location, my Panasonic TV proved uncurable. Of course,
my wife can always tape the show, and watch it after the contest.
******************************************************************************
Whatever you buy, if it is excessively RFI sensitive, might you be able to
return it (under warranty) if it doesn't cut the mustard? That might be part
of the negotiation with the sales people.
GL! I think they're getting a lot better. I have cable TV, and a 7-year old
Hitachi VCR and Panasonic TV of the same era, and they needed only a toroid
around the cable input and a toroid around the power cable.
*****************************************************************************
I have had good experiences and have heard from others that JVC brand
TV's and VCR's are good. I do not mess up my JVC vcr at all. yet i can
totally wipe out my neighbors RCA on 40 meters.
*****************************************************************************
Hi Bill. I have a 27" Sony with no problems, albeit it's a bit old now (8
yrs.). KV-2780R. A newer 20" Sylvania (Philips?) has had a weird problem
with 15 meters that I have yet to solve. When running about 300 W on 15m,
it seems that the CPU goes nuts, even when the set is off. It resets all
of the presets (channel list, color/brightness levels, etc.) Seems like
it's coming down the coax (I have cable) and have tried balanced high pass
(in case it's common mode on coax) to no avail.
As for VCR's, My late model JVC has it's share of problems.
*****************************************************************************
No guarantees, but I've real good luck with Sony and Hitachi products.
Nothing but bad with Magnavox.
***************************************************************************
Here are the model numbers and dates of manufacture:
TV: Panasonic CTN-1242R 9/91
(Susceptible to RFI 50 feet from antenna, uncurable without internal
modifications.)
VCR's: Magnavox VR9361 7/94, VR 9020 4/91
(RFI-free with high pass filter and ferrite cores on leads.)
***************************************************************************
Well, your topic isn't really contest related, but you can't contest
if you can't operate due to TVI, so I'll give you a break. :)
Take your 5 watt 2m hand-held to the TV shop and pick the set that
doesn't notice it. Pass it all round the front and back and key it
down.
Get a VCR in a metal box, use a good 75 ohm high pass filter (Ameco or
Microwave Filter Co.), plus some mix 43 ferrite beads on the coax, and
TVI due to overload should never be a problem.
Avoid big-screen TV's in big wooden boxes -- asking for trouble.
Avoid connecting stereo speakers on long leads directly to the TV set.
If you have time, call the Manfacturer's "Consumer Information Line"
or "Service Center," to ask if they have any TVI complaints about the
model you are considering purchasing, and how they handle them.
****************************************************************************
OK, I looked and it is Panasonic PV-4461, built in September, 94, so it
isn't too old. Originally I think there was some minor problems, but I
connected a wire from the cabinet to ground and there hasn't been a
glitch since. Seems like I'd be looking for vcr's with metal cabinets
and perhaps a three-prong plug. Tell folks to avoid plastic cases. I
hear alot about those suckers.
****************************************************************************
I have a Panasonic TV - CTP 2784 SF
I have a Panasonic S-VHS VCR - PV-S4266
The TV has seen "extensive testing" on 75/80, 40, 20 and some 15m
It seems totally immune to 75/80, 40, 20m. My wife told me the other
day that I was messing up the TV while I was on 15m, and it still
got into the TV at 100W power. 10m I haven't been on enough to say
one way or the other.
The VCR seems fine with 75/80, 40, 20m. Don't really know abt 15 or 10.
No idea on the WARC bands either.
****************************************************************************
Just getting around to reading this and might have a suggestion that
might help with and seems to work with just about any VCR. I have an 8 yr
old GE here and am able to keep the RF out of it by using a "common mode
rejection filter." This filter was described in CQ about 3-4 yrs ago and
seems to work pretty well.
I assume that you are also on the cable. What it entails is using a
pair of Radio shack 75-300 ohm transformers and one of their 300 ohm TVI
filters. Thew idea is to break the cable at a joint near the VCR, attach a
transformer, then the filter, then the other transformer. WHat this does is
breaks the shield of the cable to keep the RF from traveling along it to the
VCR or set. This idea has worked very well for me as I am one of those
people who has to tape Star Trek during the middle of of a major cw DX
contest.
Give it a try and see how it works for you. Then let me know.
Incidently, K8MFO tried this method to get his 6 meter signal out of his TV
and it cured the problem instantly!

I've heard that for 1995 SS each entry will be required
to make FIVE Q's on 14230 with sstv present. This applies both
weekends! I also stopped by and listened for a few moments, and
think most of them must lead a shallow life to interfer with FD
and not be out with their local ARRL club helping elmer some one...
