Hi Simon,
I brought back some PCN1900 amplifiers from my Dayton trip. The transistors
in some of these should be equally as usuable on 13cm as the Siemens units
from DL4MEA. I get 25W from my DL4MEA/Siemens amplifier (drive limited, not
output). I have also now successfully modified one of the Siemens DCS1800
amplifiers down to 23cm. I am getting 35W out but have run out of drive
there as welll. It looks good for at least 50W and the IMD performance of
these DCS and PCN amplifiers is superb on the usual 26V supply. I've also
recently obtained some new surplus amplifiers for both 900GSM and 1800DCS
and these also look good for mod'ing. I saw one of these at Weinheim already
mod'ed for 23cm and giving over 50W out. The future look bright, the future
look (well, you know!).

Now my neighbour has erected his 6 foot fence I am ready to get my 23cm EME
dish project back on the rails. Have one of the new 'Prague' rectangular
circular waveguide feeds. Hope to give it a try shortly. Kits for these may
be available soon from a colleague in Munich.

Hi Sam

didn't know about the G8MWR reflector - not seen or hrd from Glen for
a long time - think he still loves in coventry - my WBFM gear was
powered by all his work!

Thanks for the mention - I am sure the reflector will expand as word
gets round.

OK on the 3.4g beacon

Well I am going to be much more active next year - I have done DXCC
on 6m now (122 countrys!) and so will be looking for microwave
challenges now thats out my system! - think I will be concentrating
on the lower bands - have 23cms near sorted - LT23s plus 2 x 2c39's -
4 x 48 ele loops so shud be a good sig - 2.3 is lacking - only 1 watt
but been chasing some amps from US but nothing come of that so far -
3.4 - got 40 watts on that band - 1.2m dish - was going to build a
DK1UV feed for the dish so I can run multiple bands off one feed.
6cms - 10 watts and 1.2m - 10g - 10 watts 1.2m

I was chasing some 24g gear from the US and had two PCOM units lined
up but the guy emailed today after I asked him to take the lids off
the unit and photo them for me, to say that half the insides are
missing -seems he paid 100USD for empty space! ooppps!

So... hope to be a bit more active - Dave GM4WLL will prob be joining
me too.

If someone has some spare 24g gear I'll get on and activate it! Peter
PHO has given me some tips for sites so will be looking at that over
the winter too!

I fancied some 23cms EME but will have to wait until I get the dish

Maybe chat on 9cms sometime soon!

Hi Simon,
well, I believe there is or was a reflector set up by G8MWR some
time ago. I
rarely if ever saw references to it and don't know if it was ever
used. I was supposed to get in touch with Glenn to see if the UK
Group could adopt it as the reflector for the group, but I must
admit that I
had reservations about doing so and then things kind of drifted.
You already
have one new user as a result of my mentioning the group in a
last night.

You will have seen G3XDY's mention of the new 9cm beacon. I'm
pleased to say
that when I brought my 9cm transverter out of it's 2.5 year
hibernation and
connected a small horn antenna the beacon nearly blew my socks off
even when
pointing in the other direction from the beacon site and with no
visibility. The horn is inside the shack and looks through a small
These results encouraged me to try a QSO with G3LQR and I'm pleased
report that that was successful in spite of the antenna challenged
arrangement at my end. So, will we now see more 9cm activity as a
result of
the new beacon and the fact that a similar antenna arrangement to
GB3MHS has
been delivered to DF6NA in Wuerzburg for his 9cm beacon? I hope so.
will tell, but what a fabulous band for troposcatter propagation.
