And yes, it is 1.7 I am using.
Works well as far as I can see.

Hi Gordon

Thanks for the confirmation. I also find the 13cm beacon marginal or nil here - so perhaps that has been moved too.
However, trees in the easterly direction are very dense this year, so that is certainly a factor from here.
Anyway, I'll pass on the info to Geoff G4AFJ who I don't think monitors this reflector.

Received an e-mail from Leicster group as follows:
"Our Engineering Manager, M1NAS, has been on site today looking at LEX. It looks as though there may have been a possible low voltage from the psu in the bunker which possibly resulted in the beacon up the mast not receiving enough voltage. Once that fault was cleared the correct frequency around 108MHz was being generated and hopefully is making its way to the masthead box. 

We have no 10GHz rx capability at the moment as Geoff, G3TQF, our beacon man is in the midst of a house move."

As my 10GHz dish is not up today, can anyone provide an answer to Geoff G4AFJ's above request ?

The latest WSJT decoder has the ability to cope with overlapping signals - the HFers seem amazed. 
May be worth a try playing with that capability, even deliberately.

JT65B is 355Hz wide and JT65C is 711Hz wide.
It is possible to accommodate 3 QSOs in a 2700Hz  passband with JT65C
With JT65B it should be possible to accommodate 7
I think JT65A is probably too narrow for 23cm propagation dispersion. JT65B may be marginal but effective enough.
However, as part of these tests I wonder if it is worth following up a 23cm JT65C QSO by repeating it on JT65B to check its effectiveness?
If there is a high enough level of success then it might be worth using 65B for random QSOs?
If using KST skeds then it really doesn't matter as the mode can be agreed beforehand.
Of course, once QRA64 is finally released, that might become the mode of choice, even though there is some doubt about its ability to really give a 3dB improvement over 'equivalent' JT65 QSOs, according to our VHF manager and also discussed with a local coding guru who shall, to protect the innocent, remain anonymous!
Using WSJT-X permits the use of a sub band in the way described as it is not necessary to be accurately on frequency as with WSJT. All QSOs in the passband are decoded and you can select which one you want to work by clicking on the display.

165 (on all bands?) seems to fit the plan nicely and would be good if it was common across Europe at least.


Let's just use it!

We aren't going to be in anyone's way and anything to increase activity on the bands above 50MHz has to be good despite the best efforts of the Ministry of Brown Envelopes

Re: Jt65 centres of activity VHF and UHF.

SAM JEWELL
 

A and B might  not work so well with the sort of dispersion we see on some paths on 23cm (and above).
There might even be some advantage in using JT4x.
However, I suspect that the dominance of the synch 'line' will make JT65 easier to spot in the case of-off frequency signals.
Spectrum displays should quickly show if there is an off frequency signal present.
A span or dispersion of 10kHz should be enough to take care of any 'off frequency' stations whilst retaining adequate sensitivity of the display.
I have been using JT65C on EME for some years and although I have tried both JT4x and QRA64, I still find JT65 easier to work with.
Can we swap signal reports rather than just an EME style 'O'? 
-17 tells us a lot more than an 'O'

That sounds good Martin , are we going to standardise on JT65C, the same as Sam?.

I'll try to get in the shack about 20:00 local. I should be able to run JT65C on .165
I'll start by beaming inland as I don't suppose there will be anyone on JT out towards the EU mainland.

Did anyone get one of these a couple of years ago when they were popularised?  And have they survived?

I hadn't used mine for some time; then it went pop - a flash from the heater element and just cold air after that.  It wasn't well made.

Just hope the 858D hot air gun keeps going longer, it's more useful.
