I dont mind a little drift, I can work with that. 1 khz per min makes it a little difficult to listen to one signal for very long. To tune a single signal, I must tap the tuning control on top till I get it. It wouldnt be so bad on CW, but within a minute the voice becomes unintelligible.

We starting including the resistors after the reports of the drift. the pads are big enough for you to solder regular 1/4 watt in place of wthe smd resistors (in manhattan style). if you do really want them, drop a mail to and they will post a 'pinch' of them to you for free, though the cost of postage is prohibitive but they have agreed to bear it.? - f

That is indeed very generous, but I hope no North American or European takes advantage of the offer. 1/4 watt resistors are ***far too easy*** to come by on both continents for any sense to be made of sending a "pinch" of them all the way from India! Moreover, it's my understanding that this effort by RF Signals is part of a community fund-raising and money *earning* (as opposed to money *making*) project. That was one of my reasons for buying one of the boards. I'd like to see as much of that money stay in India as possible.

I think there's another issue involved here that bears some thought and discussion. So the BitX40 VFO has some drift? BFD (Big Fat Deal)! I hope I never get to the point either physically or psychologically when having to touch a VFO knob to sharpen the tuning up a bit now and then becomes burdensome or somehow unacceptable. And God forbid I would ever become such a jerk as to mar an otherwise pleasant QSO by pointing out to the other guy--more often than not a total stranger--that he's drifting (or exhibiting some other meaningless "flaw" in his signal) unless I'm **asked** for a detailed signal report.

This ongoing inflation of features and expectations needs some serious reconsideration, reflection, and soul searching. It's made possible by **store-bought** DDS and SDR technology, along with all the feature bloat that goes along with much of it: waterfalls and spectral displays and other means of finding fault with the other-guys transmission.

Sure, lower the bias current by putting in 220 ohm resistors to minimize heating. Take any other reasonable route to maximize the VFO's stablility. Figuring all that out is part of the fun. But if you can't get around to any of that, stick an antenna on the thing and get on the air anyway! If you end up offending the spectrum police, too bad for them!
