Receiving beacon but nothing else
Re: Receiving beacon but nothing else
G4WIM has reported good results using the Technomate TM1 LNB from Amazon at £7.99. I have ordered one to try. Technomate do not actually say PLL in their spec., but just say high frequency stability. However if it is producing a T9 morse tone on the nb transponder, it must be PLL.

Yes the TM1 is PLL with a 25MHz xtal ref as I can just about detect the 25MHz ref signal leaking out of the F type connector.

Yes, I've tried adjusting skew and the forward / back position of the LNB in the mount - no change
I'm waiting for a new LNB and will also try a different, faster laptop. All that leaves is my MT, but that's been proven extensively on terrestrial signals.
What's frustrating is I can decode the beacon no problem, zero errors and MER 4.

I would be surprised if a DRO LNB had the phase noise performance necessary for 333ks, You really need PLL. No need to lock it for TV though.

Have tried listening to a narrow band signal ? Just had an issue with my set up and found the LNB to be at fault. When I looked at the CW beacon it was all over the place like the PLL couldn't lock. Changed LNB and all is ok now.

Not yet, John. I've got a bias tee on the way and then I will try that.

Re: Receiving beacon but nothing else
Ray, did you get any joy with the new LNB? I have the same trouble as you (great beacon pictures and nothing else) and with two different PLL LNB's. I know I'll crack it soon, but it's soooo frustrating.
Re: Receiving beacon but nothing else
Not had a chance to try it yet. Will post here when I do, but it may be a couple of weeks.
Re: Receiving beacon but nothing else
I had the same problem in the beginning.
The problem was my Offset frequency was not exact enough so I didn't receive the smaller signals.
Playing around with the Offset up and down on A smal signal til you get A lock may help.
