PSU fro Toshiba 500mW 24G PA

g4nns <brian-coleman@...>
 

Hello All

I find myself designing a PSU to supply the necessary +5, +/-15 and -
2V needed by the Toshiba 500mW Amplifiers of which there are quite a
few about. Not wishing to re-invent the wheel, has anyone out there
got a simple elegant, tried and tested circuit for 12V nominal input.

The fictional town about which Dylan Thomas wrote 'Under Milkwood'. It's
generally thought to be Thomas' home town during his final years, Laugharne
(pron. 'Larn'), on the estuary of the Afon Taf, about 18km S of where I live.

Someone mentioned RSGB weekday HF contests; the only one I know of (I have participated in every session) is the 80m club contests. These are held on Monday, Wednesday and Thursday (one of each per month with differing modes CW, SSB, RTTY). They explicitly avoid Tuesday's to avoid clashing with VHF/UHF contests.   So Tuesday's seem like a good idea for continuing VHF/UHF contests and including more Miicrowave. I have no microwave experience as yet but plan to be on 10G CW/SSB by the spring.

I think it is essential for some unknown information to be exchanged in a contest beyond the callsign.

Neil, G3RIR

GW4DGU Activity IARU UHF/Microwave Contest

Chris Bartram <yahoo@...>
 

I will have to work for much of this weekend, however, I will try to be QRV
from my home in IO71 on 432 (legal limit SSPA, 0.5dB RX system NF, and 20dBi)
and 1296 (60W SSPA, 0.7dB RX system NF and 22.5dBi) for tropo. Look for me
early (~06utc) on Sunday morning, and at other times when I'm visible on
'KST.

I will also be QRV from around 20utc on 10368.1 during Saturday evening, but
only for EME QSOs - I can't set the dish elevation below 30degrees.

I agree that we could be better at integrating the UKAC Tuesday night events
with the Scandinavians. Perhaps the answer is to either lobby the VHFCC to
include 2.3 and up on the fourth Tuesdays, or for UKuG to piggy-back a 2.3
and up event on the fourth Tuesdays regardless! There would be very little
conflict with the HF contest they currently run in that spot.

I'm not sure what Heath is suggesting, as the RSGB VHF Contests Committee
events on the Tuesdays are coordinated (to a degree) with Europe, whereas
Thursdays would not be. The weekday NAC events elsewhere in Europe are on
the third Tuesday of the month on 1.3GHz from 7pm - 11pm CET , and 2.3GHz
and up on the fourth Tuesday at the same times. This is 6pm -10pm UK clock
time, assuming European and UK daylight saving changeover dates align.

I can't see any benefit from having another set of UKUG sponsored events -
it would be better if we encouraged more support for the existing RSGB
ones.

I agree that serial numbers should be retained (noting that the
Scandinavians don't use them in their NAC contests though!).

Hello John,

That is why I asked if you had flushed your web cache. CNTRL F5. I find that my web cache at work will sometimes give strange results on web pages I have visited that have changed since. Also, some pop up blockers and security features can stop you seeing the frames properly. It may be you are using Linux or a MAC and Safari or Konqurer and these do not work with the code on the site. Anyone who uses Norton anything is likely to have problems with everything, so check that you have not inadvertently bought any Norton products.

I hid my own non-cleverness at web site design for the RAL registration by asking for Email confirmation by a web form. (Post method = mailto). This is not the done thing, but it is simple to code for those of us unfamiliar with ASP, PHP etc. Once day I will get to understand how to do it properly.

Hi,
 
I feel strongly that better synchronisation with Europe is essential, both to boost the activity on the day and to improve relations. This particularly applies to the weekday evening events. Some time ago, I suggested that the evening microwave event(s) move to a Thursday and are administered by this group, leaving the lower bands on Tuesdays and administered by the RSGB; that idea was not well received but I still think it has merit. 
It would be a pity if there is no requirement for original information to be exchanged during a QSO, if it is possible to fill in the log before the QSO is even started, we have a nonsense. Keep the serial number and I like the requirement, in the 70MHz contests, for exchange of QTH as well as coded locator. In a contest, as distinct from an activity period, there should be good evidence of successful COMMUNICATION, not just contact.
No view on the mm bands (at least this year!).
 
73, Heath.

Personally, I was impressed. John has done a good job.

It worked fine for me buttons along the left. Did you remember to flush
your cache? Are you disabling popups?

john,

Sorry but not impressed. You send out a message to say that one can
order
food on the website and book event, but I cannot see how to do this.

There is a menu which I assume will be available but then cheques have to
be send to martlesham radio club - that's fine, but if you require us to
select from the menu at this stage how do we do it?

How do we pre-book the event or register. I can find nowhere on site to
do this.

I will have a meal and will be sending a cheque. I will be attending on
Saturday and will leave Sunday afternoon. I will book the Hotel direct.

I have investigated PCB-POOL, and assuming the pcb is 80mm * 40mm, they will do 3 PCB's as a minimum for about 76 Euro. I need 2 PCBs so I would sell one. Could you confirm the PCB size. They will accept Gerber files.

You may want to try Futurlec (http://www.futurlec.com/PCBService.shtml). They are a lot cheaper than PCB-Pool. I have used them for several PCBs and the quality is good. The one off cost for a 80mm x 40mm double sided board with solder masks and screen is $54.20. The artwork and setup is a fixed cost so 5 PCBs done at the same time gets the price down to $13.40 each - you don't have to panelize them. Forgoing the masks and screen gets the price down to $6.20 per board. Shipping is an additional $9.

IAC, please put my name down for one PCB if you decide to have a quantity made (irrespective of manufacturer).

Could you please send me the PCB file to g8zha at blueyonder dot co dot uk
Due to the MOQ of places like RS, I will have plenty of components to be able to supply the pcb and the basic resistors and capacitors needed, if anyone wants the other PCB.
If more PCBs are ordered, then the price will come down further.

If a eurocard is exactly 160 x 100mm, then it is just possible to get four on side by side.  
 
I don't know of any free software for that, do the ramblings in the latest few RadComics point at any PCB design software.   Can you read Gerber files?   All PCB houses can, although the Gerbers output from theis old EasyPC-ProX software apparantly has a few odd quirks.   PCB-Train in Newbury can read them perfectly OK though.  You may be able to get teh PCB house to replicate the file four times.
 
Really must investigate the Windoze version of EasyPC one of these days. - I have a copy, just have''t bothered to upgrade to using it as the DOS version still does an excelent job  :-)

Oh dear.

Obviously simple web pages are too complex for some people.

Look, it's really very simple.

On the main screen, there is a button marked Book on the left hand
side. Click that with the left mouse button.

Then you'll get another screen, on it is an entry that says "Register
a new person", you'll see that the word Register is a little different
from the rest, this is called a hyperlink, click that with your left
mouse button.

You'll then get a helpful screen talking about privacy, click the
Continue button at the bottom, with the left hand mouse button.

Then, as if by magic, you get the booking screen. And what is
absolutely amazing, is that the choice of food is displayed. You can
also say which days that you'll be attending, and other important stuff.

Wow, praise be!

Now, next time you have a problem with a web page, please engage your
brain before sending off an insulting message.

OK?
