Who has "changed the on-board chip capacitors to leaded polystyrene types and report good stability." With the BitX40v3, and which caps did you replace and with what values? Jer aa1of

What are you using for an antenna. I am just starting out and wondering about a rotating ?dipole ,I travel in a motorhome sometimes and thought it might be easier to put up. Sent from Yahoo Mail on

I am still having stability problems with the VFO in the 1st BITX 40 I bought in Nov /16 . Works great except for the drifting of the VFO . I ordered a second one and it arrived just before Christmas

John - depends on if the filter's bandpass is symmetrical OR the mixing scheme is kept so the IF is not subtracted. With USB you'd need to drop the carrier oscillator approx 6 kHz. Provision is

Fired the newly completed BitX40 up on New Years Eve - I'd had zero luck on 7.285, but it's probably because I'm a) in Central-South USA (Texas), and b) never the right timing. So, I toddled on down

I also found this encloser on thingiverse, but I think I will design my own. Just waiting for the kit and then I will design an encloser for 3D printing. I use fusion360 for all my designs. It's a

Oops, responded before I read the whole message. When you do get your Bitx40 send an email directly to me so that I don't inadvertently gloss over it. My email address is <mycall>@noeth-family.com -

All measurements are taken from the lower left corner of the panel (as you look at the panel from the front). For a rectangular opening, that measurement would be the x and y offset from the lower

Thanks! Where are you measuring X0/Y0 from? Have to wait until I get my Bitx40 before I can decide, so I can measure the LCD and figure out where I want the controls (I might go for a front-firing

Is it possible that the bandpass filter characteristics with the 47pF capacitor are a remnant of the BitX20's USB operation? If so, would adding future bands like 60m or 20m sound better with the

You can also do the same with the back panel. On both, I'll assume that 'lower left' means as looking at the front of the case for the front panel, and looking at the back of the case for the back

If you can let me know where, type and size of the holes you need in the panel, I'll build a printable (.stl) file for you that matches. If you'll respond with something like: round hole, d1 mm

Having a passing familiarity with the inner-workings of the FT-817, one of the problems with it is that its AGC is not well-designed. Unlike most AGCs, the time constant appears to be different for

There is a piece of software called OpenScad that is free. With it, you can import a .STL file (which is what is usually provided on Thingiverse), you can then 'subtract' cylinders (to make round

Out of curiosity, does anyone on this group play around with CAD software? I found a 3D printable box on Thingiverse ( BITX40 enclosure by Ik8yfw ) that was sized for the Bitx40 board, but it has

Mine shipped today. Woo-hoo! Hoping it arrives before the 17th, since that is when our ham radio club meets again and I am hoping to drum up some interest in the club for homebrew projects. Looking
