My TTi supplies have course and fine adjust plus the current pot is a log one. Really the best option IMHO on an analogue supply other than digital setting it via encoder/digital.
Nah, course and fine pots are the cheap way out and nothing more.
Never liked that setup at all and refused to stock anything with them.
Right PITA compared to a 10t pot with a good heavy knob that does a few turns when you give it a flick.
Bloody pot cost more than the rest of the transceiver cost.
Sure buying 1x but for manufactures that but them buy 1k, 10k or 100k how much will it really add to the retail cost of a PSU ? Bugger all and provides a nicer cleaner layout.
This is why digital setting has taken off .......cost and better preciseness......but I'm amused you prefer dual pots to 10t or digital but it all depends on how digital is implemented. Encoder only, numeric keypad, up/down buttons or some combination of any/all of them. HW costs of digital has to be cheapest but how it's implemented is the key to usability.
