Hi All,
I am thinking of doing some changes to my 2m antenna set up.
One thing I would like to do is improve the front to back ratio.
If my memory serves me correctly a second reflector placed behind the first
reflector will archive this, however if so, this would increase the boom
length.
Is there some other method that could be used to improve the front to back
ratio?
Thanks.

Hi to the list,
I own an Kenwood TS-790E Transceiver.
Today I wanted to try the DO-64.
I've set the radio on CW and sent it on air.
I've noticed that the S-Meter stopped on 4 of the dB line.
Without touching anything and just passing from CW to FM I saw the
S-Meter needle going up till over the 9 of the dB line.
Before I made these test I have set the radio with 10 watts in FM.
I have measured the SWR and have noticed that there are none high SWR but
Just 1.3 on both modes but I saw the power drop down to 5 watts in CW
While it was 10 Watts on FM.
Please anybody can tell me what has happened?
Thanks.

Hi,
another method is to use another antenna to form a phased array.
This would contain the length, but will increase the setup complexity, cost,
weigth and "width" (the second antenna must be placed at a given distance
from the first one, typically a quarter of wavelength).

Drew,
It was my pleasure & thanks for giving it a try. You signals were
weak, but 100% copy on the 2nd pass. I'm glad we were able to make
it happen! This was my first contact with Alaska via AO-7 (all
others have been via AO-51) and a new grid for me.
Hope to work you and/or other Alaskan stations (W1AW/KL7) via
satellite over the next few days/week during the Alaska Hamfest/ARRL
Alaska Convention.
73,
Doug KD8CAO

Good question! I was going to send you the standard response
saying she is napping in the dark, but just did a quick check
myself and PCSAT (W3ADO-1) has not been heard since 2 July at
11:52:39 and the last station to digipeat through it was SP9UX
on the 5th at 04:09:14 and the last USA station was W4AEJ on the
1st at 14:04:28...
But I also notice that PCSAT passes are at night over the
Northern Hemisphere where everyone lives. Maybe we can wake up
someone down-under to see if they can listen for PCSAT (W3ADO-1)
NO-44 on 145.825 MHz... May not decode it, but should be able
to hear it attempting to send a packet once a minute.. Only in
the sun, of course...
So Robert, thanks for bringinig this to our attention... PCSAT
was launched on 30 Sept 2001.
Bob, Wb4APR

Hi, I own an Icom 910H and would like to add a pre-amp for 70cm any
recommendations? The AG-35 is a possibility, I like the connectivity with
the rig, however I can't find any N.V info on the unit. Advanced receiver
had some nice units, any ideas would be terrific, thank you.
