Hi Tony
It ended up as annual as the single trip was 10 quid dearer.

Mine has gone up from £80 last year to £249 this year, and that's the lowest I could get

But of course if posted by me it has to rubbish and a lie.

Re: Es'Hail 2

Surprise of the day! Beacon "CQ CQ DE ES2HAIL" - on appx. 10489,650 MHz (non stabilized Octagon OSLO). Measured at 42 dB S/N relative noise in 2,7 Hz BW. Using 80 cm offset dish. Beacon stopped 13:48 UTC. 73 Ole OZ2OE

Den 16. januar 2019 kl. 13.28.44 +01.00, skrev SAM JEWELL via Groups.Io <jewell@...>:

Excellent signal from the beacon in the amateur nb transponder.
The transponder noise floor is 15dB above the out of band noise in 244Hz resolution bandwidth (the default on my RSPPro2 SDR).
That is quite substanial and indicates that we should not worry too much about the ultimate noise figure of the Octagon LNB as the transponder noise floor is likely to set the ultimate SNR we will have on signals.
My measurements show the beacon (or maybe it’s a test signal that is pulsing, so may not have caught the actual peak) at about 30dB above 15Hz resolution bandwidth. It certainly sounds loud, sending its CW identifier.

Well done to all involved in the Es’Hail-2 satellite and in particular the Amsat-DL team. 
I didn’t look in the wb transponder passband. Hopefully, all is well with that transponder.
Looks like time to sort out the uplink set up.

Re: diplexed transverter link

Andy G4JNT
 

The only thing that's critical is the cleanliness of the recovered 10MHz.  Since that is treated non-linearly when it reaches the synthesizer (squared up, divided, etc.)  ANY other signals present, even at low levels will contribute spurii to the PLL reference.  AND if any high order  IMD product generated from this falls within the PLL bandwidth, you're in big trouble.

I'd suggest that NO other signals should be visible at all on the recovered 10MHz when you look deeply using a spectrum analyser on low RBW (other than harmonics of course).   In fact, I'd recommend at least 80dB down
So very good filtering of the reference after it emerges at the top end.   Since it's the lowest frequency present (ignoring DC of course) that shouldn't be an issue.

Re: diplexed transverter link

Dave Brown
 

Tks guys- only query I have then is what the isolation like between the low  and the high frequency pass bands?    When using this scheme with a transverter the worst case level difference is probably on receive with say 0dBm at 10 MHz and maybe -100dBm or less at 144 coming out of the transverter.   Tx would not be as bad with say +36 at 144 going up the cable to the transverter and 0dBm at 10 MHz. Probably will be other factors for the tx situation anyway,  to cater for the higher power requirement at 144.

Regardless it would be useful to know what sort of isolation you’re getting with that triplexer arrangement.

Re: diplexed transverter link

Bob Lockley VK6KW
 

Hi Dave,
My 2c worth:
What is the IF frequency? If it is well away from 10mHz a diplexer at both
ends should work ok.
If the 10mHz is also used for timing there may be significant delay as
opposed to having it topside - depends on how accurate the modes in use need
to be.
Switched DC on the coax should work but begs the question as to how the
masthead unit is being powered? and what else is there?
73,
Bob.
