Re: 3d printable enclosures?

 

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 great CAD software and there are a lot of tutorials out there. And it's free.

So if anyone has some ideas for an encloser and could make a drawing with measurements, I could turn that into a stl file for 3D printing.

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 @noeth-family.com - where is ka9bgt.

I don't have a Bitx40 (or 20), I've been watching the group because I've been thinking of buying/building one.? I'll probably not go with the Raduino, as I already have a SI5153 based digital VFO built, so I'll probably just copy that one.? I built the one I have for an antenna analyzer.

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 speaker, as well, if you can do a pattern of small holes, or slots!). If you already have a Bitx40 with the Raduino, maybe you could make the front/back panels to your tastes and put it on Thingiverse; it might make a good start for others as well.

Re: 3d printable enclosures?

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 left of the panel to the lower left of the opening.? For a circular hole, it would be the x and y offset from the lower left of the panel to the center of the hole.

For the rear panel (if you want that one as well), it would be the same, except the lower left would be as looking at the rear of the enclosure.

I already have the skeleton SCAD script put together, just need the size, type and location of the holes to complete.? I agree that AutoScad can be somewhat daunting at first, since it doesn't have a graphic interface.? But, once I got it figured out, it's really not that bad.

Re: Improved audio from the Bitx40 (video)

 

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 47pF capacitor or would the characteristics be the same regardless of which sideband is used?

Re: Receiver comparison

 

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 weak signals (<S9) than above, but this has to do with the unfortunate "volts/dB" curve of the AGC control voltage: For weaker signals, it is reasonable, but for strong signals a small change in voltage = more dB. The net effect of this is that the AGC seems to be inconsistent in the manner described.

When I use my FT-817 - particularly on a busy or noisy band - I make use of the attenuator to keep the S-meter in the "lower half" (<S9). In this way, one avoids the de-facto audio compression that seems to occur when the AGC is in its upper range where the time constant - even on "slow" - is faster than what one would ever choose intentionally.

Interestingly, I've not see this AGC problem discussed much as its cause isn't immediately obvious and I have not ever seen any attempted fixes but it does explain the sometimes "heavy" sound attributed to this radio. If nothing else it can serve as a cautionary tale to someone designing their own AGC loop.

Re: It stopped transmitting

 

If the final bias adjust preset is untouched then the IRF may have failed.

Check the voltage on the left side gate pin of IRF (facing you) it should be a small value,
I don't have my boards with me here at the farm!

It could be the driver or predriver. Whichever is running hot when you press the PTT!
