That's very sad. I met Frank at the First Thorn EME conference.  I took a photo of his Children sat laughing on a park bench. With Geert PA3CSG's late father. It was the very last photo of him. 

I brings back many happy times

Re: Digifest this Evening

Ole OZ2OE
 

Enjoyed last night and this time nearly working G4DBN. The small common volume and the (relative) few planes passing in the middle of North See makes it hard, so we have to get the most from a few short reflections. In our case I agree 15s is too long.
As a contrast I worked DL7QY at abt same distance (actually 25 km longer). Also small common volume, but with the heavy air traffic over middle Germany, there were audible reflections nearly every 15s period, so easy QSO.

Looking forward to next Diginight.

I always try to announce the freq, mode, period and tx time when working someone, plus direction when CQing. Best approach is just to ask the ops if they are on KST.  JT9F-fast seems to outperform ISCAT for aircraft scatter on 23/13cm, but for weak tropo there are better slow mode options.  15 second overs are too long really, but some setups get into sequencing and relay problems at shorter intervals. With a reflection peak lasting less than 20 seconds, 15s overs mean you need at least two planes.  5s is a bit short, 10s a bit long, 7s would be a nice option!  I nearly made it with OZ2OE but we only have a very small common volume between us, so once the planes thinned out, we had to give up. Two periods of decode one way, one period the other.  Very close.

Hoping for some action on the other bands soon, particularly 3cm.

This was my first participation in the Digifest, and I’d like to thank all those who attempted QSOs with me.  Under flat conditions I really need suitable planes north of the Scottish Central Belt to be able to work into the north Midlands and north of England, although they were again scarce yesterday evening.  However, I did prove to myself that my system was working with Gordon GI6ATZ, with whom I had my first FT9F-fast auto-sequence QSO, exchanging -04 reports over an easy 428 km path.  Fascinating to sit back and watch the QSO progress!

 

Looking forward to the next one, and I’m happy to arrange SSB/MGM/CW skeds during the daytime when planes are usually more plentiful – just e-mail if you’d like to try.

It was quite interesting again, I got a new DXCC when I worked GI6ATZ
which was a very nice result. It seems that for me 600km is relatively
easy, which is of course related to the aircraft availability. JT9F does
exploit short duration paths quite well despite the reduction in
sensitivity. My relays are quite happy with 15sec periods.

No replies so looks like no one using an FT-847 as an IF anymore.
Done the mod and it does work fine both on original and external references.
After a bit more research the mod should also work on my other radios. I have an
FT817 and will mod this when parts arrive (ran out of suitable resistors).
The mod would also work on a TS-2000 but already have the 2000's locked using a
German board so won't do it on these radios.

Subject: Using an external reference for a Yaesu FT-847

Wonder if anyone has used the VK3HZ mod to use an external 22.625MHz reference on
a Yaesu FT-847 ?.
The mod looks pretty simple but like all things I want to check it works before going inside
the radio to do the mod.
The other alternative is to just use an external reference, but should this fail the radio will
stop working until re-applied rather than falling back onto the original oscillator.
Have looked at locking to a GPS reference but not available any more so the VK3HZ mod
looks like the easy option.

Yes, boards will be available by New Year. They are here but still need to be cut from the panels, and then I need to work out a price including P&P.

Digifest this Evening

Martin A Hall <gorrell77@...>
 

For a change I’m not working this evening or any Wednesday evening until 10 January, so I am planning to participate in the next few Digifests, on 23cm.  I intend to come up on ‘KST from about 6:30 PM, since if last night’s UKAC is anything to go by aircraft will become more scarce over this Highlands as the evening progresses, although I plan to stay around all evening monitoring aircraft movements and activity while I’m undertaking construction activities in the shack (ref-lock and the 13cm system).

 

I now have WSJT-X up and running with the replacement control PC.  Although the previous set-up under Win 10 worked fine until the hard-drive failed, an almost identical replacement didn’t.  The RS-232 connection on the replacement PC simply refused to work; I can speculate as to why this might have been the case – the original PC had been upgraded from Win 7, whereas I believe the replacement was a new install.  Whatever the reason, I’ve had to purchase a good quality USB to RS-232 cable from Lindy with the correct Prolific chip set for Win 10 (older cables containing a previous chip-set that worked with Win 7 don’t work under Win 10) to interface with my PTT sequencing system.  I’m mentioning this detail here in case it’s of any value to anyone experiencing similar problems.

 

Thanks to Noel (G8GTZ) and Andy (G4JNT) for the wiki at https://wiki.microwavers.org.uk/Digital_modes_using_WSJT  I’m now set up for JT9F-fast and 15 sec period, and the system seems to work.  Running about 100 watts into a 60el with masthead VLNA-23.  Looking forward to some QSOs.

Hello Eric

Thank you very much for that link. It adds nicely to my collection of Adret data. It is interesting, as someone who was designing RF electronics at the time the 7100 series was being manufactured, to see the progressive development of that range of generators, and the F6EVT site, by including the 730 and 740, I can now understand even more about the earlier instruments. This work is helping me a great deal with my reading of the French language, although I doubt whether my spoken French will ever be anything other than an embarrassment!

Those schematics answer my question, which was concerned with the

different. The oscillator enclosure has a label saying : Type 629,
Frequence 80MHz, No. Serie 101310, and No. Ordre 13. Does that give an
indication of the possible schematic?

I've used Adret Signal Generators for many years, even buying one new

their performance. Even now many years later, they are still much better
