¿ªÔÆÌåÓý

I've used a mouse wheel for robotics projects. You should be able to make it work.

If your scrapped mouse is a 'track-ball' type, remove the ball to remove the temptation from the kids to swap it to their old 'junker' PC. Pop in a large nut from the garage/workshop's junk-heap to lend weight if required.

You may wish to take this opportunity and remove the nano and as I did solder in a inline header so you can remove future ?Nano's.?
A low profile socket is helpful so you can later connect the display module sandwich.

Re: Still Not Working

 

Reads like the Nano is blown.? Just plugging in the DDS into your USB by its self should show it booting etc. with version displayed then random numbers 'cause you don't have the tune pot plugged in etc.? The Nano runs the Si5351 with 3 volts from the Nano on board 3v regulator. ?i suspect the 5 reg. gets really hot to the touch.
I've been running my BITX from a 12V. battery.."works fine_Last long time"
Looks like a new Nano is needed.
Hope that helps for what it's worth.

Hi Mike

Thanks for the tips

My DDS has jumpers on J1 J2 and J3, and it¡¯s definitely an AD9850 with 3 rows of 7 pins. I have e-mailed the seller in China to see what can be done. I have limited test equipment, but I¡¯m taking it over the weekend to a fellow amateur who has a spectrum analyser to see what it is doing

Assuming your DDS is the type that has three rows of seven pins be sure that the jumper at J3 is in place.? Also, not that there is an easy fix, but you might check to be sure it¡¯s an AD9850 and not an AD9851.

Together with the recommendation to use buffered output for the VFO this clarifies wireup a lot.

Re: Still Not Working

 

In the "wire up" section of HFsigs.com, under "alignment of the bitx40" it says to turn RV1 (PA bias) fully clockwise (off) and with an ammeter in the PA power lead (so you are measuring only the current to the PA, not the whole radio), adjust RV1 for 100 ma with PTT activated but no mic audio. After that, RV1 should not be touched. R136 which is usually about mid-point when you get your bitx40, is the only control that should be adjusted to get about 1A on the ammeter when you key the mic and talk loudly into it. This is when transmitting into a proper 50 ohm dummy load, as a poor SWR can mess up your measurements. For example, the wires to the antenna connector should be no longer than a couple of inches long, if a longer distance is needed use 50 ohm mini coax to avoid causing a poor SWR at this point.
Don't "daisy chain" grounds or power connections to different circuits. The 3 grounds and 3 power leads (from Raduino, main circuit board, and PA power) should all go to a common tie point near the DC entry point on your enclosure.
Don't allow wires to lay on top of or up against the underside of the circuit board. All wiring should be kept above, below, or to the the side of the circuit board about a half inch if possible.


Re: Still Not Working

Vince Vielhaber
 

Grab your voltmeters guys. Check the input and output voltages of the 3 term regulator hanging off the side.

Also try unplugging the connectors going in and plugging the Raduino in to your PC.
