W3ZZ posted a question about IC-737 performance but failed to add his email
address for the answers. I hope that mainly USA audience on this reflector
may find it interesting that RSGB reviewer Peter Hart found IC-737A one of
the best receivers he ever tested! He was able to measure filters bandwidth
down to -70dB without being adversly affected by DDS VCO noise. Dynamic range
was over 100dB and respectable 70dB with only 3 kHz two tone spacing.
I am proud to announce that IC-737 has the signal chain exactly the same as
my good old IC-735. VCO is greatly simplified by DDS approach.
The only feature missing is decent RF clipper instead of two diodes in AF!
I feel both IC-736 and IC-738 are a very good value for money although older
IC-765 has the best receiver I expierenced so far.

Once again, equipment problems bedeviled us. We missed 4 hours Friday
night fixing things that blew up or fell down. If we ever operate a 160
contest from start to finish, we might be dangerous.
Outstanding opening to Central Europe Saturday night. Worked UA3, SP,
YL which is a fair haul from here on 160. Missed EB and ND when we
were off Friday nite, but really enjoyed the EU opening on saturday.
Equipment: Inside: OMNI-VI, Ameritron AL-1500, NA9.12
Outside: Inverted L hung on a 60' tower, elevated radials
Also, "flew" a Deltal Loop for 30 min. on Friday
nite with a kite (til the string broke), and for
about 9 hours saturday (bought another kite).
Was a fun experiment, worked real well, somewhat
labor intensive. 4 two-wire beverages, 2 1050',
2 550'.

Condx seemed fairly good, tho QRN was occasionally a hassle.
I was surprised how well sigs held up in A.M. after daybreak.
We had about 993 Q in 71 domestic and 15 dx. Best sig award
to AB4RU on right and W6QHS on left.
