Testing Coils for inductance..
that old LARU is perfect, 0,1µH to 1H. The power cord was rotten, the instrument self typical Rohde+Schwarz of the 60s, still allready working.
It is a resonance tester.
For comparement i used the Tek 130, the test coil is a 270µH
130 is not a resonance tester.
bd139:
Tek 130 is an interesting and very nice bit of kit. I built half a clone of one of them (must finish that) using slightly more modern tech. It uses a fixed and variable oscillator and measures the frequency difference by mixing, passing the sum product through a filter and then counting pulses. When you zero it rather than adjusting a bridge you’re synchronising the oscillators to zero beat.
Cerebus:
Our weekend ebay fraudster is back, this time as bigmike13 and using a slightly different off-ebay payment route, but with the same items and photos as before.
When, if ever, will ebay get their act together to automatically alert themselves to this style of listing? If I can spot it every time, why can't they?
bd139:
Yeah I've seen and reported that already. Tossers! Doesn't require a lot of clue from ebay.
Decided to shift some stuff today to make room for more toys, including the 465. At least there's an honest seller out there ;)
Edit: also bought another QRP labs QCX and enclosure. Woot.
