As ARISSat1 now is opertional in high power at a decent hour in the evening
here I have been making a few attempts at SSB transponder operation.
I have 2x10 turn helix atennas and a 100 watt brick amplifier which
would give me an ERP in the order of 4KW on the 70 cm uplink.

At 11:08 UTC Aug 7 morning pass with 20 degree elevation
VE3NPC and KB8OTH competed a QSO on ARRISat-1.
Signals were just above noise level but Q5

It is commendable to see some direct antennas comparison measurements being
made.
Computer modeling is one thing. Realizing it in hardware is quite another.
The biggest problem in making field measurements is to reduce and try and
eliminate reflections
from the ground, adjacent structures and
There is also the possability the FT-847 is a early production model.
The original design did not include two-way CAT control.
Models withe serial number 8G05 or later provided full CAT control
I have an early unmodified FT-847 which will set the designated doppler
corrected up and down freqs
I made over 1300 contacts on AO-40 during its 2 3/4 years of operation.
The first QSO was on 05/05/01 at 08:17 with Mike N1JEZ on U/S
then at 08:39 worked Dom I8CVS, at 08:52 Fred CU8AO, and at 09:03 Frank
DL6DBN.
I then fired up my FT-736R on 1.2 GHz and at 09:44 worked Steve KB8VAO with
To add to the discussion the July/Aug 2007 Amsat Journal has an article
covering some gain comparisonmeasurements I made between four
13 turn (2.88 wavelengths) 13cm antennas with different square solid
aluminum reflectors.
The sizes were 0.56 wavelengths, 0.84 wavelengths, 1.0 wavelength and
Mode V/S working well on orbit 30820 on 10:20 UTC pass.
Full quieting for whole pass with only one small fade..
Only KB2M and myself on.

I worked OX3DB on AO-13 on 5th Jan 1990.
The card says the operator was Jan Nielson and his QTH
was Nuuk (Godthab) on South West Coast.

Hi Erich
I now have almost the same problem.
I had version 11.4 on my COMPAQ laptop running windows XP.
I have been using it with an interface to tune my Yaesu FT-736R
particularly for mode L and S on AO-51. It has worked well for
several years. But every year when I renewed my AMSAT-NA
On for 20:45 and 22:25 utc passes. Early one was max elevation of 15
degrees
next one nearly overhead pass. Receiving with 52 turn helix with cup
reflector
No signal background noise is S1. Max sig on 15 degree el pass was S6 and on
near overhead was S9 + 10db. Had 2 QSOs on low pass and 4
Received my K5D sat qsl in mail today.
Thanks for a new one.
