Few days ago I copy Javier , KH2QII/KH6 , on 14076 JT65a
with peak -16dB (!) - he report that using 30 watts vertical.
I try call him with 100 watts and 6 el YAGI and he told me that no

Today I am CQing on 14076 and few stations on West Coast reports that
copy me with no less then -20dB

I wonder why some folks bother with phone, especially under weak conditions.
It sure is fun to just talk but the performance of SSB phone versus other
modes continues to amaze me. Trying for the LOTW TP award has caused me to use
SSB phone more of late, and I am often encountering situations
Andy,
This is a topic of discussion that is raging on behind the lines in
Emergency Communications also.
The fundamental thing that many miscalculate is how the Intel that is to
be sent digitally is gathered and relayed to someone with the
capabilities to digitize

I know your point is really about digital modes required S/N, but a bit
of a pet peeve on the CW operations it's perceived usefulness as a

When it comes to emergency communications, phone is not an option, but a
necessary mode for most conditions. It is the only practical mode that
gives you the instant knowledge that someone has received your

such cases due to
I am tempted to try get active on 6M-70cm for digital modes and CW this summer.
I am looking to avoid multiple runs of coax and thought of a homebrewed log
periodic for these bands, using one feedline . Does anyone here use one, or
have favorite software for log periodic design? Is the
Hi Andy,
I operate 2 meters and 70 cm every day from here in Mount Pleasant. You
really need 14 dBi of antenna gain on 2 meters and 17 dBi on 70 cm to
reach 200 miles on phone if there is no propagation enhancement. A
log-periodic will probably not have enough gain on any one of the bands
it
Andy,
Another excellent high gain antenna for either 2 meters or 70 cm that
can be homebrewed is the quagi:

You will be happiest with at least this much gain on either band.

Thanks Skip, I had a K1FO design 2M beam but took it apart , too big
for me. I also have old large 2M and 440 cross polarized Yagis
laying in the garage doing nothing , but again too much antenna for my
back yard these days. Your SS5 skeleton-slot beam is a clever
design. What is the actual
The SS5 is a true skeleton-slot beam with five skeleton-clot elements.
Each one is a skeleton-slot.
The overall dimentions are 13 x 2 plus the width:
Reflector width: 7 5/8
Driven element width: 6 1/4
D1 width: 6 1/4
D2 width: 6 1/8
D3 width: 5 7/8
I standardized on the height of each
If everyone is running the same antenna oriented the same way then it ought to
be reciprocal paths. However that is rarely the case and it would seem not too
unusual that forward and reverse paths are often different, sometimes
substantially so. I'm always amazed how many verticals I can work
