Re: BITX40 build for SOTA/POTA operation

 

I like all these antenna options, but I do have to find a way to operate w/o a tree. The MI parks ask people not to run anything up into trees because of concerns about moving parasites around. I am thinking the tenkara fishing rod option or possibly a magloop. Mag loops seem to get much simpler to build when you're talking QRP power (no vacuum capacitor needed).

Raj,

thanks a lot, now it compiles too on my Pc,

Der Sketch verwendet 5882 Bytes (19%) des Programmspeicherplatzes. Das Maximum sind 30720 Bytes.
Globale Variablen verwenden 592 Bytes (28%) des dynamischen Speichers, 1456 Bytes f¨¹r lokale Variablen verbleiben. Das Maximum sind 2048 Bytes.

so only 5,8 kB

thanks a lot!!

Re: BITX40 build for SOTA/POTA operation

 

Nice case peatmoss. I like that you brought out a usb connector so you don't have to disassemble every week when Allard has a great new software upgrade. It looks like another pot without a knob was also added. What is it for?
I usually just carry 2 lengths of 1/4 wave wire on a winder. I throw one end up in a tree and lay the other on the ground. The downside of a half wave is that you need a longer wire which is tougher to get up in the air. The plus is that if you can use a half wave wire you can get the high current point up in the air.

I too had trouble with the driver for the Nano in the BitX and had to download it from somewhere. Don't remember where I got it unfortunately, but it wasn't from the site mentioned above. Never had the problem with the Uno or Megas.

I still haven't figured out how to load your code in the original chip. My ancient windows 7 machine won't recognize the chip and allow a write. Thought it worked initially because the LED on the raduino came on, but no code on chip.

I will keep plugging away trying to sort it properly.

Re: raduino v1.27 released (improved suppression of spurious burst)

 

Allard

Your software is impressive!?

I have been using v1.25 and adding in some features for my BITX40s (x2) - Voltmeter, SWR and S-Meter.? ?Space and ports represent a major issue now!

I note your interest in using one of the PLLs instead of the BFO.? This would be great!?

It would also make it easy to add in PBT and adjust carrier offsets and not have the issue of USB being subtractive (so not as deaf - unless you remove the caps in the VFO buffering stages).??

I am in the process of adding the following features/mods:
  • Multi-banding using the QRP-Labs relay boards (LPF and BPFs)? ?- Requires 5 digital I/O ports (or 10 if you want to drive relays directly from a port)
  • 2 Rotary Encoders with press switches (requires 6 digital I/O ports)
    • one encoder for tune control (press switch to toggle between 10khz and 100hz steps)
    • one encoder for selector control (rotate to step through the menu - VFO A/B, RIT, etc. and to set defaults, and press switch to set menu item)
So, I need at least another 11 ports and some more program space and SRAM!? Ideally I would like band stacking registers for each band, which will demand more memory!

My feeling is that it would be good to decide collectively, on where we go with the processor!? ?Choices seem to be:
  • Arduino Mega Mini Embed (available from China for around US$8 including headers).? This is functionally the same as a Mega meaning tons of room and ports.
  • Maple Mini STM Clone (BAITE) - About US$5 - very affordable and solves headroom problem and it has sufficient extra ports (particularly if the display uses I2C)
  • Teensy 3.6 (or earlier) - but about US$30 each.
I am tending to favour the Mega Embed as this has tons of ports and code shouldn't need much in the way of changes (some ports shift of course).? However, the Teensy would provide for DSP as well in future, albeit at greater cost.? There are readily available SI PLL modules that would be mated to any of these devices.

I would be interested in what others think.? ?I would really like a better? UI (User Interface).? Pushing a button multiple times is not really very user friendly, and rotary encoders can do the job so much better for both menu select and tuning functions.

Re: 80 Meters on BITX40?

 

Further to the LPF modification for 80m, I have done more experimenting and found that if you switch in a 470pf cap across L6 in the LPF, you will get about 37db attenuation on 40m, with a nice rolloff from 80m.?
The attenuation on 80m is negligible. See the attached graph.

Re: raduino v1.27 released (improved suppression of spurious burst)

 

Hmm, maybe possible. But this would take extra program space and we're
already tight. I want to implement digital BFO first (v2) which also needs
some space.

If we would have 4 VFO's then we also need to consider how the SPLIT
function should work.

I discovered a bug that the carrier burst is still not properly suppressed
in CW-SPLIT mode. Normal (non-SPLIT) mode works OK.
I'll correct that soon.
