It is so hard to "accept" that AO-51 is failing when is sounds SO DARNED
GOOD as it is right now over the Western United States.
THANK YOU, AO-51 Control Team members.

I have for some time wondered what was causing a considerable amount or QRM
(S9+60dB) to the ISS downlink on 145.800. It took a while to identify as
there is no CW ident etc. but I have now discovered this is a new D-Star
repeater on our repeater channel RV63 which is 145.7875 MHz, only a couple
of kHz from ISS and inside the doppler shift range. It seems very poor
planning to place high this powered high sited repeaters so near to the
satellite allocation. Is this becoming a common problem and are repeaters
also causing any problems to uplinks?

As I recall IARU Region 1 (Europe&Africa) approved the use of 145.7875 MHz
for repeaters over a decade ago.
You're right it's unworkable with the ISS operating on 145.800 MHz +/- 3kHz
doppler shift and with 5kHz deviation.
Unfortunately that was what IARU Region 1 decided despite having agreed
earlier to 145.800MHz being used for ISS.
That decision means there are a large numnber of FM and D-STAR repeaters
using 145.7875MHz. Anyone near to a 145.7875 MHz repeater will suffer
considerable interference when listening to the ISS downlink.

Hi Domenico,
Uum not quite - The Austrian conference paper refers only to repeaters that
have been established INSIDE the segment of the band allocated to satellite
operation ie above 145.800MHz.
The RV63 145.7875MHz operation has come as a result of the adoption of
12.5kHz channel spacing for 2 metre repeaters back in the mid 90's. Before
that time the highest repeater output frequency was 145.775MHz - albeit
with a higher deviation than now of course.
Here in the UK we have seven FM units and one DSTAR unit on RV63

If you just received an eQSL from me and have previously sent one, please
