Subject: [amsat-bb] newbie question Icom 910H & LEO antennas

> Although licensed for 55 years + , I am just now an SWL on the birds. I
did Oscar 6 in ~ 1975. Having worked and confirmed all of the DXCC countries
and just recently retired, the birds have my interest. I have plenty of 1/2
inch and 7/8 inch hardline and connectors as well as a Kenpro G 500
elevation rotor. I have an Elecraft K2 with their transverter and a
Microwave Module with satellite capability for 435. Just need some antennas.
I am also thinking of getting a more modern rig and the Icom 910 caught my
eye. A friend of mine has a Yaseu 736 which he will sell me with 2 and 440
modules. No price discussed yet but I thought $700 would be my top. As an
alternative I thought about the Icom 910H. The only concern was a comment I
read on EHam that it was not user friendly on the FM birds being more
friendly to the JA birds. Is the 910 capable of doing AO 51 OK or is it a
pain ? Often information can be misleading. This is my first post here on
the BB. If there is any bird oper!
>  ator close to Cincinnati, Ohio , I would love to visit your station. I do
have the old style Mirage bricks for 2 and 432 too. I thought of Egg beaters
from M Square but now leaning more toward the 10 foot long circular yagis
for 2 and 432.

Hi Jim, W9VNE

I also started with OSCAR-6 and since you have capability to use
transverters and Microwave Modules to transmit and receive in 2 meters and
70 cm you are exactly in my actual operating conditions.
I suggest you to start again the satellite activity  with VO-52 and the old
OSCAR-7 using the familiar CW and SSB operating practice.
I suggest you to simply start with separate equipments one to transmit and
the other one to receive and manually compensate for doppler as you did with
You will be very happy to use your old 2 meters and 70 cm transverters
because using VO-52 and OSCAR-7 you will find a lot of friends in those
linear transponder allowing many QSO's at the same time similarly as you did
with OSCAR-6
You only need to put up again your KR-500 for the elevation and two
circularly polarized antennas one for 2 meters and the other one for 70 cm
possibly with relay to switch between RHCP to LHCP
About the antennas I suggest you the KLM 2M-22C or KLM 2M-14C for 2 meters
and KLM 435-40CX for 70 cm
As soon you will be ready to operate VO-52 and OSCAR-7 you will find again
the same excitements that you already experienced with OSCAR-6

Have fun and 73" de
