GB3MHX

SAM JEWELL #303 Hi folks, I am pleased to announce that GB3MHX (10368.830MHz) located in JO02PB, Martlesham, returned to service ealier today (26th September) with an increase in output power to 0.5W into the antenna. This should make the beacon more suited to rainscatter propagation monitoring. The frequency of the beacon has also been reset to the correct frequency. It was about 8kHz high after more than 5 years of non-resetting (crystal aging). The new frequency was measured to be 800Hz low of .830. Normal diurnal cycling in the tower room will cause the beacon to settle about .830, but further crystal aging will mean resetting again in about 12 months or so. There will be further news of a new beacon at Martlesham later from one of the G4MRS team. regards Sam

gm4plm <simon@...> #305 Thanks Sam I will add that to the next columns.

SAM JEWELL #308 Hi Simon, well I subscribe to the Tom Williams reflector and find that most useful. I wondered how long before someone would (seriouisly) take to do the same here. I think it will fill a long held need. Congratulations on setting it up. 73 de Sam toggle quoted message Show quoted text ----- Original Message ----- From: "gm4plm" <simon@...> To: <ukmicrowaves@...> Sent: Thursday, September 26, 2002 8:26 PM Subject: [ukmicrowaves] Re: GB3MHX Thanks Sam I will add that to the next columns.

Congratulations on setting it up. 73 de Sam Hi Sam Well I sat wondering if someone already set one up and I was missing something, but then realised actually no one had! Maybe thats been the problem! And to be honest it took all of 30 mins to set up the group as I wanted as the admin. But as I said I don't intend to interfere (unless things start getting nasty!) but just let it run. Hopefully people will join in as time goes on, it will take time to get the word out. So far in 2 days we have 22 members and I am sure that will rise after the weekend's activity. I also subscribe to the US microwave reflector and there are some regular UK names on there too so it made sense to have a UK version. What worried me most was that things are happening in the UK and people are missing the info/news/for sales etc and that is a shame. We have some seriously clever and advanced microwavers in the UK but everyone seems to be doing their own thing and there seems to be lack of a focal point for whats going on. So that was the idea - it should be useful and so far I have been encouraged that it will do so. I just can't believe no one got round to doing this before! I used Peter PHO's email list for the first round of invites and if you don't see anyone on here you think would be interested in it then please let them know the address where to find it. I am not sure if having to have a yahoo acct puts some people off. It shouldn't. I never receive anything from Yahoo unsolicited unlike MS! I will publicse the address in the next set of newsletters and hopefully that will also encourage some activity. thanks for the support! (still looking for that dish !) regards Simon GM4PLM

SAM JEWELL #313 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 widely used. I was supposed to get in touch with Glenn to see if the UK Microwave 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 conversation 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 mutual visibility. The horn is inside the shack and looks through a small window. These results encouraged me to try a QSO with G3LQR and I'm pleased to 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. Time will tell, but what a fabulous band for troposcatter propagation. 73 de Sam

gm4plm <simon@...> #314 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 sorted. Maybe chat on 9cms sometime soon! regards Simon GM4PLM --- In ukmicrowaves@y..., "Sam Jewell" <jewell@b...> wrote: Hi Simon, well, I believe there is or was a reflector set up by G8MWR some time ago.

SAM JEWELL #316 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. 73 de Sam toggle quoted message Show quoted text ----- Original Message ----- From: "gm4plm" <simon@...> To: <ukmicrowaves@...> Sent: Friday, September 27, 2002 3:38 PM Subject: [ukmicrowaves] Re: GB3MHX 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!

In actual fact there has been a UK one for some time, run by Glenn Ross, G8MWR ... it's called waveguide@.... Unfortunately it does not get much support these days even though many of us subscribe to it. Good luck with this one Simon! 73 Peter, g3PHO
