Argh this week gets worse. Looks like car has decided to piss out half the contents of the radiator. Fortunately this only became an issue as I was parking. No unicorn for me.
Thus if anyone wants a punt at my unicorn, Marconi 2022E with no output on a bunch of frequencies due to a bust 250-353MHz VCO, knock yourself out. Probably a very easy under £10 fix. Almost certainly a bad cap or BFR91A transistor rather than the usual irritating OM345 fixes. I was going to go and collect it as I don't want to risk it getting munted in transit as the front panels on them are fairly fragile.
Gonna go and fucking sulk for a couple of hours now instead
Haha, looks like you gonna get a second chance of having the Marconi 2022E after all then. I guessed the unicorn was going to be something by Marconi and also guessed a frequency generator as the tinySA stops @350MHz
Meantime, I'm still pulling my hair out with the PL310
. Calibration of the voltage is sweet as a nut and bob on, bloody current though is being a bastard. Set the current for 10mA as per sheet, fine, short the output and adjust VR8 for a reading of 10mA, it aint happening, 55mA is the lowest I can it set to. As for setting the current to 900mA on an external ammeter, nah, it aint happening either, 124mA is all I get out of it.
Haha, I feel just like Basil Fawlty, going to get a branch from the tree in the garden and beat the PL310 with it
