While in sunny southern California this past week, stopped by Jun's
Electronics in Culver City.  Picked up the latest copies of the DX Magazine
(9-10/96) and Communications Quarterly (Summer 96).  There are several
articles that should be of interest to the CONTEST group.

DX Magazine has an article which compares the KT34XA's gain with the TH6DXX
and several 10, 15, & 20 monobanders using the YO software (AD4MQ).

Communications Quarterly has the following:

(1)  FT990/1000 Interface Circuit using the band data output to control
external devices (AD5X).
(2)  4CX400A Russian Tubes for the MLA-2500 Amplifier, modification (<$350)
allows for economical tube substitution (plus higher power) (W4OIW/6).
(3)  Data On Long-Path Propagation at low latitudes and solar minimum (NM7M).
(4)  Modeling and Understanding Small Beams - Linear-Loaded Yagis (W4RNL).

73 and good reading,

     I know there are a few Fs and VE2s on the reflector...   I need to 
     apply for a French license and need to tell the French administrator a 
     few things, and he speaks about as much English as I do French.
     I need this....   last week, so the sooner the better.

Is there any solution ofr a noisy fan on a TS-930 short of replacing it?
Mine has been getting progressively louder over the last 4-5 years and has
finally reached the intolerable level.  Contest season is coming, after all ...

Prepping for SS.  What do people think about the usefulness of 40 and
80-meter inverted vees at about 50 feet?  I had them at 90 feet (apex) last
year, and felt that the 80-meter IV was a great domestic antenna but the 40
was a tad too high.  Now I have a rotary dipole at 100 feet on 40, and I'm
thinking of moving both IVs down to 50 feet or so.  too low?  Would 65 feet
be better?  Or where? I'm also putting up a parasitic array for 80 that
models to be a killer on lower-angle stuff, so the 80 capability from the
inverted vee would be mainly to fill the domestic gaps.

Does anyone besides myself have trouble getting certificates from the CQ
contest people?  I still have not received wallpaper from 1993, 1994, and
now 1995 for WW Phone.  I have written everyone except Hiram Percy Maxim
and he is one of the other guys.  Tnx.
