What should I do with the unit?

P.S. I'm in Australia.
P.P.S. As a replacement I'm eyeballing the TAPR/TICC option but AUD$54 in

I see no attenuation at 1376 MHz (close to GPS frequency) when observing
pulsars with a radio telescope. Even the brightest pulsar (Vela) is so much
fainter than a GPS signal which boom in when they happen to pass into the
telescope's beam.
It definitely happens at higher frequencies though. Up ar
Hi All,
I have the Tasmanian unit of the German made TTL based speaking clock
running in my garage. I've kept it going since it was decommissioned in the
mid 2000s. In true Time-Nuts fashion I have it synchronised to the GPS.
For extra fun, I broadcast it on FM 107.7 using a (legal) low power

Hi Luis,
I have experience with the NASA NR series if that’s what you have. Blue and
about the size of a household fridge, wth lovely 80s red LEDS on the front.
If it is this model, I’d expect it is more likely that your ion pump(s)
need replacing.
I can send all the documentation you need.

I remember walking into the Greenwich Museum for the first time, NOT

Hi All,
Thanks so much everyone for your comments. I especially liked "get the
orange one". Because that's what I did get (I think it's orange - could be
yellow).
I was deliberately vague (apologies) but I just wanted a broad response.
Which I got.
I've settled on the Fluke 87V. It's on it's way
Hi all,
I think I'm in the market for a new digital multimeter.

Interesting read.
I've been programming since the mid 70's (started with a 2650 and TI59).
Graduated in Computer Science and mathematics in 1984, did Honours in
Computer Science in 1985.
Fast forward decades and I completed a Masters in Astrophysics and a Ph.D.
in astrophysics as well.
