Hello I have an Elrisa 22W 10 GHz PA for sale, it is pre tuned for 10.368 GHz and produces 22W when driven from a Kuhne transverter. I have 2 that I was going combine for EME but will use a single device instead, the other one I will keep for terrestrial.

 

If anyone has a known good GU78b I will do a straight swap.

 

Please send offers to my email. I accept paypal

Hello Dave

One of my first steps when looking for a text or paper is to go to the IET Library. I think thats one of the main reasons I continue to pay my subs! They have been very good at finding odd (sometimes very odd ...) publications.

Thank you Chris. I must admit that I don’t make much use of my IET membership - I should try to use it more. Sci-hub is my usual source for any scientific paper, but it doesn’t cover books. I don’t know whether sci-hub will ever cover out of print books, but books that are still being published, so the authors still receive payment, would go against the ethos of sci-hub.

Hi Ian,


If you are comparing buying new from Siglent or used from, say, HP or Tek I would say that the new equipment has the advantages of being much smaller and lighter,
Yes
a nicer screen
Yes
and can easily generate data and screen shots. 
Yes
Not to mention warranty,
Yes
serviceability etc.

Now, this is where I disagree. The chances of you being able to service a Siglent in a few years once it is outside its warranty period, is a bit remote. I would say you have far more chance of being able to service HP/Agilent kit than any other make.
 
  I have bought a fair amount of used equipment in the past to avoid the very high costs of new test equipment, but these days you would have to think quite hard about these lower cost offerings, unless you really need top end performance.
 
A used high-end instrument is going to hold its value a lot more than a new Siglent too.  The used high-end stuff has done most of its depreciating.


Hope this helps.

Re: Siglent, Telonic, Lab

As my name was mentioned, I thought I'd better reply...

The Siglent 3032X is good enough for me, but I wouldn't say I'm a particularly exacting user. Before I acquired it, I visited Telonic and Labtronix and took with me an ex-cellular 900MHz BPF with 80dB stopband and a pair of battery-powered 70MHz crystal oscillators a few kHz apart combined with a 6dB hybrid. I persuaded the salesmen to press the buttons to my requirement. Neither was particularly familiar with the instrument, but both managed to do what I asked - a how-easy-is-it test. The Siglent could get further down (70dB+) into the stopband of the filter, both gave a creditable picture of the two-tone oscillator with no signs of intermods down to the noise at 60dB which was likely the oscillators. The Siglent doesn't have a touch screen. With both, if you narrow RBW and VBW too much you can wait tens of seconds for a scan! Previously I had use of an HP 8558B/HP182 mainframe and I've taken photos from its screen in similar circumstances which implies both Rigol and Siglent could apply more DSP.

The SIglent has an ethernet socket but support is via National Instrument software which I'm not about to get involved in. I haven't found any information that would enable me to write my own beyond using a socket and SCPI (primitve) commands

Using my Siglent over the last 2 years I have only the usual niggles about the user interface that you get from anyone with any piece of equipment.  It sometimes corrupts a screenshot file being written to a USB stick; there's no 'safely remove' menu item and I now wait 20 seconds before unplugging.  I had trouble with a licence key not accepted; you need one to enable the extra features. Labtronix sorted it out very promptly. I've had a couple of firmware upgrades with no apparent change in performance.

Service/warranty in both cases was return to factory, not in UK. Siglent have an office in Germany. I now see that siglent.co.uk takes you to a Telonic site, they now sell both Rigol and Siglent! Other support aspects may have changed since I got mine a couple of years ago.

Hope that's of some help; happy to correspond off-list if it is of interest

try looking at

Close but not the one you are looking for, I have the RSGB VHF Technique 1948,  Bayliss and Williams  just in case there is common content from that era?

Re: OT - 144 MHz TDK circulator wanted

Conrad,
The one on my photo is for sale, 100% OK, currently tuned at 144.3 MHz. See my "for sale" page at PA0P.com.
Price is EURO 20,- (plus 7.50 shipping cost, but you may collect it if you're coming to direction the Hague)

Regards, Cor PA0P


Re: OT - 144 MHz TDK circulator wanted

Conrad, PA5Y
 

Actually Cor it turns out that these are rated at 50W reflected and having just tested at 100W with a 2:1 VSWR they are fine for my application.

 

I bought 2 of them for my 2m IMD test setup, so I will have to find 2 more now.

Hello all,

 

Sometime ago there were some TDK circulators for 2m doing the rounds, they were good for 150W on 144 MHz. I gave mine to the GB3VHF boys 😉 Anyway I am looking for 2 more, please check your junk boxes.

 

Many thanks and HNY.

Re: OT - 144 MHz TDK circulator wanted

Hello Cor, no I have 2 of those for my IMD measurement set up but they are only 50W, I need 100W handling. The ones I want are TDK and handle 150W with N types. Or of course anything else that is similar.
