I have received the spare parts from some very kind folks in the US and the instrument now seems to be working fine again :-)

Still got to soak test it and do a few checks but it's looking good so far.

Many thanks for all the help and suggestions; I can now get back to my 24ghz project :-)

23cm/13cm September UK Activity Contest

Christopher Bartram <cbartram@...>
 

Ray's comments about last night were interesting. A look at the 00UTC pressure
chart on the Met.Office site (the oldest I can easily find) shows an occluded
front running approximately N-S between us. Presumably that was playing havoc
with the refractive index. Certainly it took its toll on the 70cm ANG beacon,
which unusually disappeared.

The 400km E-W path to Sam 'DDK seemed to be less effected, and I could copy
his tropo signal without too much trouble, while the AS enhancements were
occasionally helpful.

Apologies for disappearing at about 2100. A neighbour arrived for a chat, and
finally left a few minutes after the contest finished...

Hi Ray, yes i can only agree with you about AS operating techniques.
One or better 2 breaks in 1 minutes periods are neccessary, also qrq
helps a lot. I like AS very much, i works as on very well in the 500km-800km range, if the vertical opening angle of the antenna is not too narrow. Maybe yagis are in favor here?

Sorry you missed it Mike.
It was sent Monday but missed Monday's digest posting time and I've no
idea when that is normally due to occur.
The event itself went off very well indeed despite conditions being
very poor indeed. They were as miserable as the weather which up here
was that horrible very light but consistent rain with very poor
visibility.
Alan GM0USI arrived at 7pm as arranged, to do his own thing on 13cm.
My evening meal was running late so it was a case of a quick greeting
and then out with my dog as Max was due a comfort break.
By 7.30pm I was into the garage and grabbing the mast base I use with
my caravan, a pole and rotator. These were then passed up to Alan in
the loft and the skylight window was then removed. Cables, poles, 35el
13cm Tonna and rotator were quickly put together and put through the
window. A thin plastic decorating sheet was used to stop rain getting
into the loft by jamming it under tiles. Alan set up his gear and I
organised his PC side for KST. All done and tested as the clock ticked
8pm.....phew!
I hadn't had time to do a beacon check but I realised things were
going to be challenging once the first contact attempt took place.
Where the heck was Chris GW4DGU's troposcatter signal?
This turned out to be the story for a lot of contacts and it was just
a case of patience and waiting for a convenient aircraft to enable
communication to take place by aircraft reflection.
John, GM4LBV was much weaker than usual and Jim GM3UAG in IO87 who is
normally just above the noise in a very bad direction for me was
totally inaudible. There ain't that much air traffic between Glasgow
and Aberdeen unless it's low flying military training exercises trying
to get late season tourists to jump out of their skin.
With the poor conditions I'm sure I missed out on a few "regulars" in
the north of England unless they were absent but overall I ended up
with my best "points per qso" ratio of the year at 422 as most
contacts exceeded 500Km thanks to AS. Success with aircraft reflection contacts is never guaranteed but do
rate very high indeed. John G3XDY took me back to my 2m SSB meteor
scatter days during our contact. We were operating 30 second periods
on CW and reflections few and far between. I was sending a "roger"
report within my exchange to let him know I had everything except
"rogers". After almost 10 minutes I eventually started receiving a
weak set of rogers and then half way through his 30 second period he
sent "break" (BK)....phew, I shot in with rrrrr BK and he replied with
73 and I did the same. The moral of this is that if you are trying a
contact using AS and you start to hear your partner during there
transmit period then when it comes to your turn then don't assume the
reflection is going to last all of your 30 seconds and be prepared to
"break" to enable some rapid contact information exchange. Contacts this month on 23cm were;
GW4DGU IO71 450KM KST AS
GM4LBV IO86 141KM KST T
G4BRK IO91 517KM KST T
GW8ASD IO83 332KM T
G4DDK JO02 572KM KST AS
M0GHZ IO81 521KM KST T/AS
G4PBP IO82 399KM KST T
G8OHM IO92 425KM T
G8DKK IO91 518KM KST T/AS
G4EAT JO01 572KM KST AS
G3XDY JO02 565KM KST AS
GM0UHC IO85 52KM T
Nobody was heard randomly at all.
All my CQ'ing generated 2 contacts and one qso (G8OHM) was a tail
ender. Alan GM0USI/P advised me he'd had one contact with Ian GM0UHC on 13cm,
had heard John GM4LBV but heard nothing from Neil G4BRK and David
M0GHZ. Hopefully he can try again and be blessed with good conditions.
Fingers crossed for good activity and improved conditions for next month.

Sunday's Cumulative Contest

Christopher Bartram <cbartram@...>
 

This contest clashes with TWO(!) microwave EME contests: the microwave leg of
the ARRL EME contest and the ARI SSB EME event.

I'll be QRV on 10GHz EME on Saturday and Sunday from home. Unfortunately, my
EME system is not usable on tropo.

I intend to try to be QRV on 24GHz (2W/3dBnF/50cm dish) on Sunday, from maybe
11am onwards using any one of several sites in SW Wales. From my preferred
location at Crug Iwan, (SS132132) there appear to be a number of either LOS
or single diffraction paths. There's a very nice LOS path to Dunkery,
f'rinstance... It would be wonderful to hear a signal other than my personal
beacon! (200mW on 24048.800 (+/-10kHz) with a HB 16dBi sectoral horn pointing
190T from IO71SV29)

After last month, I will have 2m talkback, having resurrected a modified
IC202S which has been in store for a few years. I'll have 80W, 9ele, and a
seriously good 2m receiver :-) even if my frequency calibration on that band
will be worse than on 24GHz!

Digests

Christopher Bartram <cbartram@...>
 

Hello Mike

Many of us now only take the digest...
That's a great pity. I've always enjoyed and appreciated your contributions to
this list. Particularly as you are able to offer a (very!) well informed view
of areas to which few other members are able to contribute with any
authority.

One of the attractions of this, and other mailing lists to which I try to
contribute, is their immediacy. If you choose to wait for the digest, you
shouldn't expect other people to make adjustments to suit your choice! I say
this, having subscribed to the digest form of one mailing list, which has
nothing to do with amateur radio, since 1991...

Re: Portable KST access

Hi,
What I'm using for mobile KST acess is my Iphone. It works a treat!
Even if the GPRS/3G modem in my laptop cant get a signal! I've tried
it on many hills and its great. The data transfer level is quite low
so I'm not going to eat up into my download limit. Before you try
this though, its best to check how much your paying for data connections.

The trick in JO55KR was to get the phone to camp on the local base

Ok, I will add a warning. I guess it is because all USB controllers

You may like to add a further tip to your page. As far as I can see,
windows seems to use separate settings for each USB port, thus you
need to plug your phone into each port and do the set up. I failed to
do this and 1mb of data was downloaded before I noticed the leak.
