It's possible with highly mounted, high gain antenna. But if you know better... Don't have to believe...
Why 28V ? I tried 2N3632 and soviet KT's

I used 6.8mH coil and 2n2222 in metal case... But circuit works well on 12V varicap voltage too - only tuning range is narrower and then need to be tuned also by coil
Surely not all of the Chinese multimeters are that bad? What multimeter would you recommend?Albert H wrote: ↑Fri Mar 06, 2020 11:48 pm If you're going to get serious about building gear, you're going to need a good multimeter (NOT a cheap 'n' nasty Chinese one), a dummy load (there are plenty of plans to make your own on the 'net), an SWR bridge (NOT a CB one - they're largely useless at VHF), and a dip meter / absorption wavemeter (the poor man's spectrum analyser). You'll also need a bench power supply - you can get away with a CB one (or a car battery) at first. You'll need a selection of hand tools, and I'd recommend a temperature-controlled soldering iron. You'll also need a drill with a selection of bits and, possibly a small model-maker's drill for drilling PCBs.
I can put some basic circuits up here for you to try. These will give an introduction into what can be achieved using ordinary, cheap components.
