>From much of the E-Mail lately, it seems that the OMNI VI may be the
performance/value leader in the transceiver market.  In a market so dominated
by the Japanese over the last decade, I wonder if TenTec is willing to really
listen to the customer and make those changes to the Omni VI that would make
it the clear winner?  It seems obvious to me that any changes that make a
contester happy will benefit the HF community as a whole.

What changes are needed in the OMNI VI to correct the major irritants?  What
do we want to see from the OMNI VII?

Hey TenTec, anybody listening?

I stopped by International Radio and Computers this afternoon and had a 
nice chat with Peggy, KB4LRD, who is the wife of the owner (Rod, N8RT).  
Here's what i found out:
     1. Their computer business was sold a while back, and their phone 
number went with the business.  They still have the radio repairing and 
filter business ("IRC"), but it's been moved to a back room due to the 
expansion of their much bigger business in the same building (a Honda 
motorcycle/jet ski showroom). 
     2. Unbeknownst to IRC, their two filter suppliers, both in Japan, 
closed down a while ago.  IRC did not learn of this for some time: seems 
it is illegal for them to talk directly to a Japanese company, so they 
have to go through an agent over there.  IRC's agent (of 16 years) 
apparently knew all about the supplier closings, but chickened out when 
it came to telling IRC the news.  (Among other things, IRC gave their 
suppliers a 50% down payment when placing their tri-annual orders, and 
they have lost that money, at least for the time being.)  In fact, IRC 
had to eventually go through the Japanese Consulate in Miami to reopen 
the lines of communication.
     3. IRC, through their agent, has now lined up two new suppliers 
in Japan.  If all goes according to plan, IRC will get a shipment of CW 
filters in two months.  SSB filters will be delayed beyond that.  (Sorry.) 
     4.  Their source?  I dunno -- but Peggy mentioned that Kenwood put 
through a 30% price increase on their filters the Monday after Dayton, 
then never shipped them.  "I think they use the same source we do".  
Peggy indicated that she and Rod would like to sell their Honda showroom 
and radio servicing business and "sort of" retire, but they intend to keep 
the filter business as a retirement business.  "We would sell it, but no 
one would pay what we want for it; they'd think the price would be too 
I told Peggy of the concerns expressed on the reflector about the delays, 
etc. (but only hinted at the rude treatment that so many had complained 
about getting from IRC in the past).  Peggy seemed very willing to talk 
to hams, and very sorry at the problems that had arisen (which she said 
were beyond IRC's control in most cases).  You might thus want to ask 
for Peggy personally if you ever need to contact IRC:

Good Luck!!  73 de Walt, AC1O/4   "AC1O at sunken.gate.net"

Yeah, even more incredible is the 10 meter beam at 200'!  As you said, I think
all the lobes help sometimes with the wierd stuff you get on 10...
But I dont think we miss a stack on 10 either.

For some reason, tho we havent been very successful on 15, so we've been
trying all sorts of things...but as it turns out we may have had some feed
problem with one of the antennas, so who knows... anyway 15M at LPL is just
getting a refurb...  73, Tyler KF3P

I think anyone who puts as much effort into making a contest happen, get
properly reported, awarded, etc. and is still enough of a competitor to
play hard and well enough to win ought to be able to do both.  Besides,
having the sponsor, coordinator, or whatever you want be "current" as a
contester contributes to the contest being improved by the sponsor each

May I make a suggestion that I find works really well for me:  Instead of
using the RIT control, put the rig in the split mode but on the same
frequency, receiving on VFO A and transmitting on VFO B.  That way you're
using the VFO A as the RIT.  Punch it into the "scratchpad" memory.  Then
when you're off freq, just hit the mem recall and there you are.  Works like
a charm on the 'ol TS-850S.

My 11 years old contest software has CW PTT implemented from the very begining
with 2 dots delay (40ms minimum).  I use Ready_To_Send signal in case of RS232
interface, 3k3 resistor, 1N4148 reverse polartity protection diode and NPN
transistor with decent DC gain.  Same RTS signal is used to delay RTTY AFSK 
tone in order to prevent hot switching.  And my 20+ years old SB-220 lives
happily with BY graphite tubes...  73 de Mario, S56A, N1YU.

All the major airplane manufacturers have spent considerable dollars
providing physical "feed-back" on the control sticks in their "fly-by-wire"
airplanes so that it feels like the "old style analog" types (with cables
going out to the flaps etc.).  Even though the computers do all kinds of
neat stuff for the pilot, they still want, and some say need, the tactile
feedback/sensations that they acquired when they learned to fly on other
aircraft.  Big, big bucks are being spent exploring all kinds of control
sticks other than the traditional wheel/stick based approach that most are
familiar with, but the pilots for the most part don't seem to like them.

Funny how certain types of interfaces between humans and machines just seem
to be "natural".  Interesting that the interface between the operator and
the radio would be similarly affected.  

In the case of the radio, is it a matter of nature or nurture?
