The  recent issue of QST has a review of the JRC JST-245 that makes it sound
like a great deal PLUS you get 6 meters (and antenna tuner and room for 
a zillion filters, etc.) So, the reveiew sounds good and lots of talk about 
870, OMNI, FT-1000mp, etc.   IS there a contestor (got in in TREY!)
who owns one ?  One of the dealers is in Ohio (Universal) and sounds
like service is possible.  Any interest in this gem (even NEWKIRK liked

Greetings!  I did get a 40mtr wire in the air and had some fun.
Lacking the details I will guesstimate my results.

209 QSOs X 50 MULTS? = 16k approximate score  about 5 hours on the air

15 sounded DEAD at 1800Z but picked up later in the afternoon.  I didn't
try 20 until later and was surprized that anyone could hear me.  My old
40 wire never got out on 20!

Subject: Ladder filters
Message-ID: <03cf94b0 at maila.harris.com>

     Ladder filters are nonsymmetrical, but once you have more than one in 
     series and the Omni V/VI has 3, the effect is minimal (unless you are 
     an uncompromising teutonic purist).  One of the perverse features of 
     crystal filters their not-well-understood nonlinearities.  I prefer 
     ladders in this regard. The internal node impedances are much lower.
     All lattice filters have transformers in them and I have seen quite a 
     few in which the teeny xfmr core was limiting the signal handling 
     performance of the filter. Ladder filters have no such encumbrances.
     Technically and practically, ladders vs lattice is a non-issue.  
     But of course, I'm biased.

     Market surveys are not their long suit.  Since I left in '85 and K4FW 
     is no longer active in the daily operations, T-T has had limited 
     contest-oriented input to their product design goals.

I think Bill is right... I don't know that much about DSPs, but doesn't
the Omni's run at 25MHz? Modern processors like the 604 are running 
at well over 100MHz with more to come, and extremely high bus rates
and wide buses. The 604 can do a full double precision Multiply and Add
every cycle, so 100MHz would be a peak rate of 200 million double
precision ops per second. (And they're a lot faster than 100MHz.) 
That's a LOT of number crunching!

Most modern processors have sophisticated interrupt structures and 
can handle real-time applications quite well. So you can still have 
all your other junk running, it'll just run slower when you're using
the processor for your radio.

TACO, huh?? Oh, well, guess I can still drink coffee during the 'test!

Someone (I lost the message) asked me how the FT-1000MP will handle QSK.  I
spoke with Chip at Yaesu who reported that the forthcoming FT-1000MP (and
also the current FT-1000 and FT-1000D models) can operate QSK with amps
like the Alpha 87a using a solid-state switch (with the internal mechanical
relay disabled).

Whoever emailed me wanting to purchase my FT-1000D (all options installed),
please email me (direct, not via reflector) again.  I also misplaced your

Subject: Omni VI - Potential Contesters' Dreamradio?
Message-ID: <32950825003523/0006492564PK2EM at MCIMAIL.COM>

Welcome to the information superhighway, all aboard!

After a contest there is someone on the contest reflector who volunteers to
collect the score rumors...he will then post the results of his collecting
to the reflector for all to glean knowledge from and enjoy...

As an active OMNI VI using contester who wants just a lil more from Ten Tec
I hereby volunteer my services as far as collecting comments for Ten Tec as
to how they could improve their radio for the competitive radio user.

I know Trey likes to keep his reflector clear of all non-contest traffic and
by addressing comments to myself for compilation and then submittal to Ten
Tec we can do just that. If interest exists and Trey would not mind I then
could summarize these results down the road. OK - senor Dos?

This could be a very interesting exercise in just how powerful we as a
community are when it comes to affecting a radio's design. Contesters
arguably have always been on the leading or cutting edge, we are the ones
who want the rig to work its best at of all things - making contacts!

Unless someone objects to this approach - send me your wishes, your dreams,
your - "they'll never put it in" hopes...the Omni VI is a very good rig, and
I think many - including myself - would argue that currently its receiver is
the best in a contest. If you want the headphone jack on the backside of the
rig so you don't always bump into the thing - let me forward your e-mail to
that effect!  I'll try and generate a cover letter highlighting the "main
beefs with" that the community has and the major "I wish it hads" as well as
forwarding all the actual e-mail messages. If you wish to remain anonymous
please be sure to say so in your message, I will edit your address out of
the message.

It is in my best interest to demonstrate to Ten Tec that maybe a lil
firmware alteration could make a button push turn that remote tuning knob
turn into an RIT control for contest run time, that alone would make me all
warm and fuzzy!

I am particularly interested in hearing from owners of Ten Tec rigs, as I am
sure that their comments as people who have demonstrated their willingness
to invest in a first class transceiver will be heard better by Ten Tec.
Contesters spend more money on their antenna farms than any other segment of
the ham community - and for years, amplifier manufacturers like ETO have
designed and marketed their amplifiers with contesters in mind. We are a
powerful voice when it comes to spending money on our hobby - why shouldn't
there be a rig that is full of the features we need?

Count me against any sort of No-Play rule for contest sponsors.

p.s. No matter what you do, even if you're K1AR, you're never gonna beat me
in *my* contest on *my* birthday, neener neener neener. Even if I don't 
operate. So there.

p.p.s. Geez, I hope conditions get better soon. Perhaps everyone's sense of
humor will return too.

I think it would be great if people sent their comments directly to Jim
and then he eventually summarized to CQ-Contest.  The key here is 
sending your comments directly to Jim and *not* sending them to

Similarly, I think it would be great if we could do something similar
with claimed scores after contests, where they could all be posted to
one place and then posted daily in one big chunk, maybe with a summary
at the top.  Anyone wanna volunteer to do that too?  :-)
