It'd be nice to get some voice going from home again.

Ciemon,

probably the cheapest way would be a transverter and that would at
least give you a chance at tx'ing as well.

building a kit is not beyond you - I know ur technical enough and
can handle a soldering iron. Down East Microwave make a single board
unit but my suggestion (if no one can come up with anything) is a
DB6NT unit. Complete single board unit and abt 200mw out so pretty
good to get started.

yell if you want some info!

Re: cleaning 2c39's?

gm4plm <simon@...>
 

OK well I will have a go - the metal work on them is grimey and the
only time I have seen this is with cig. smoke.

sort of yellow tarnishing

I will try - if the anodes get corodded thats no big deal as they
are getting water cooled anyway!

thanks Ted!

welcome to the group BTW

regards

Simon

They have all survived but I do mark them with a Black permanent ink

Try this URL, Simon, there's a lot of information for new and

Thanks Adam

yes the net and books are full of ccts but I wanted to know what
people experiences of them were and which actually do the business
rather than look good on paper :-)

I will take a look at that site - think perhaps I already been there!

appreciate the link anyway

GB3ANG

gm4zuk <gm4zuk@...>
 

Hi,

I have looked after the GB3ANG (IO86MN) beacons on 4m, 2m and 70cm
for some years. With the generous help of Frank GW8AWM a beacon was
added on 23cm back in December 1997. For pictures of the beacon
antennas look at http://www.qrz.com/gb3ang

For some time I have toyed with the idea of adding 13 and 9cm
beacons. Mark GM4ISM has offered equipment for 9cm but I have little
equipment for 13cm.

My first question is would these additional beacons be useful for
those in the South and the near continent?

Unfortunately, it is far from certain that the site owner would
permit any further equipment/antennas. I would be interested to know
other microwave operators thoughts before I go any further.

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.

Anyone got any info on this meter??

I would like to know what model heads it can use??


Hi Simon,

I've sent, by direct email to you, a pdf file giving info on the power
meter. It's taken from an official Marconi Instruments 1980/81 catalogue I
happen to have!

Looks like it uses the same heads as my 6460/3 powermeter. The heads are
available in 10mW, 100mW and 3W max input. Usually the 100mW ones go for
around 45 second hand. If you find a source please let me know! I have one
spare but would would like another, perhaps a 3W one or one going up to
18GHz. Most of the surplus ones go up to 12GHz OK. Some have waveguide
input but most I've seen have an N socket.

These heads are VERY fragile. Drop one onto the bench and it will most
likely not work again. Overload them and they are faster than fuses!

Your meter looks nice, being programmable.

Cheers,

Peter, G3PHO

Also - WR62 anyone?

Hi again,

Also have some WR62 (WG18) SMA launchers. Professionally made,
another by Sanders, N termination and lock ring flange. Price about
£5 or haggle why?

I also have some secondhand runs of '62 available in copper -
if they're any use shout up each one is around 1.5M long rough ends
that need squaring off, and the odd small spider as tenant hi

2 x 2c39 - cloned EME23150 (G3VVB)

Does anyone have any paperwork on these amps?

I think it was a clone of an EME23150 done by G3VVB.

I am interested in tuning and output probe initial tuning positions

HP X486 Thermistor mount

ajm2k1370 <adamory@...>
 

Hi my first contribution to the group

Can anyone use a blown X486 thermistor mount for spares or
anything. I have one which has one thermistor down. The compensation
thermistors are however okay. I know it's a bin piece really, but if
there's someone who can make use of it, it's theirs for the postage.

Thanks
