One last Summary Dunestar & I.C.E.

[C.T. Morton]

Final, Final summary:


Just had a wonderful (see below) weekend with two 1500 watt stations
whose
linears were next to each other...both stations used ICE 419 multiband
filters.
Initial results from 3830 and the reflector indicate we did rather well!
1445
X Sweep, #1 high claomed score so far.

    I am sorry for my late reply to your post. You may want to send
this out to the everyone else as well.
    I have been frustrated with ICE's low power bandpass filters. The
bandpass loss was higher than ICE's specs. The return loss isn't very
good and the adjacent band rejection does not meet their published
specifications in many cases. I made all of my measurements with a HP
Network Analyzer. I have had filter failure at the 100 watt level
during contests as well.
    I took my desires for the ultimate bandpass filter to W3NQN last
year. During the past 9 months we have worked on a 200 watts
continious duty, high performance filter for each of the 6 bands.
During CQ WW phone we used these filters on 160, 80, 40, 20, 15 and
10. They are VERY good. THe filters were also used at HC8N, KS9K and
N2RM. The bandpass loss is much better than ICE or Dunestar. Always
less than .5 dB. The adjacent band loss is better than 40 dB. The
return loss is better than 25 dB for all models. They are available in
SINGLE BAND units, custom made and tuned/ tested.
I have NO financial interest in the filters, but I am the point of
contact for obtaining them.
15 and 10 meter versions of the filters are just now in production.
160 through 20 are available now.

Let me know if you need more information.

I haven't operated QRP since I did the CW SS and CQWW back in November of 
1989.  I used homebrew equipment that I built in the early 1980s before going 
off to college.  I think I was running the "legal limit" (5W output) and a 
couple of G5RV antennas that were not very high up.  I made about 500 QSOs in 
each contest, all S&P.  I remember finally finding VT Sunday night of SS and 
calling it quits (I think I missed two sections that year, YU/NWT and maybe 
KP2 or PQ).

I always felt SS was a good contest for the QRPer.  The distances were 
reasonable (i.e. not DX) and 40 meters (my first QRP/homebrew band) is a darn 
good band for SS from the Northeast.  I still remember working W5XJ and N6TR 
(in California) in 1978 or 1979, early in the morning (10-11Z) for two new 
states on 40 and my best stateside DX at the time.

Yes, high power is fun, but there's a lot of opportunity for the low (or very 
low) power guy in SS (look at KR0Y's score).  I'm glad that the comments on 
the QRP-L have been favorable.
