Looking for a noise figure meter to measure some preamps. Usual suspects Eaton / Ailtech / HP. I thought I had the relevant option in my VNA to do this, but it seems that the software option is enabled when some pieces of hardware are in fact not present....

Alan, Have you seen this.....
https://wiki.batc.org.uk/Portsdown_NF_Meter which mentions CQ-TV 274 (Winter 2021) Depending on what gear you already have...

Sadly I don't have the hardware already for this - although I'm tempted to buy a Pluto SDR module. But I did wonder if anyone having acquired a nice small system like this would be trying to get rid of a boatanchor noise figure meter....

Hi Alan
I do have a Magnetic AB Model 117 Noise Figure Meter (1960s vintage) which you would be welcome to collect (from Salisbury or any of the BATC-attended Rallies in the South). Working when last powered up about a year ago. Sadly, I do not have any spare noise sources to go with it.
Not quite a boat anchor - only 12 kg!
