Hi Michael Thanks for the reply. Ok on the next update from Allard. That will be ideal if the mode problem is solved, I will patiently wait until the next release. Regards Peter G4NJJ

Now that I got Han's attention, I'll start a new thread. Not quite true.? The output MSynth is as reported, low integers but not in integer mode on the few random samples I've tried so far. The PLL

Also, I wonder if a modular design approach could be used, instead of monolithic. Say a better AGC is devised at some point - how to upgrade/replace it? Same question for the filter banks, what about

Looks pretty awesome!? Can I recommend using headers for the Teensy?board (as opposed to directly soldering to the board). It adds a little to the cost, but saves headaches down the road when

You are correct, the LFP caps see half of the peak-to-peak voltage, since that RF is centered on ground. In Farhan's example of 3000 ohms at 10W: Vrms*Vrms/Ohms = Watts? ? so? ? Vrms = sqrt(Watts

Hi All, the encoder readme file has been updated to note 100 nf capacitors from each encoder contact to ground. New file attached. Rod KM6SN

Farhan An interesting question. In the LPF, does the capacitor see the peak-peak voltage? It is connected to ground. So, doesn't that mean it sees the peak voltage (1/2 the peak-peak)? 73 Hans G0UPL

Han's, Thanks for a definitive statement. A selection of filters and a nice relay switch double sided daughter board would have being nice and I wasn't expecting to be able to use yours for circa 40

Should work, Fred. See what I did with QRP Labs filters in the Multi-Band BITX40 link in my signature below. It works very well down to 80m and I'd love to see what you do for 630m. I'd like to try

Hi ALL I put encoder interrupt code on github at https://github.com/rodKM6SN/encoder-interrupt There is a readme.docx that gives an overview. The code is a hacked subset of a large project, so there

I have a new BitX40 that I am testing on the bench before building it into a case. Right now, it is all stock and I am just testing transmit audio to see how it might be improved. I can receive my

Mine arrived today too! You just got to find the inner strength to wait! 73 Steve

Peter :? I believe that Allard will be releasing a V2.0.3 load in the not too distant future. I have been working with him and another list member to Alpha test V2.0.3.? I believe that the issue you

Not long got home, and opened the box. Now to start the process of working out enclosure sizes, layout etc. Need to get it up and running first tho. Mines F37/1, so an early one in the first batch,

The auto tuner capacitors have to be rated for the highest voltage at the highest impedance. This is an extreme requirement. To illustrate, a 10 watt RF signal will put out a peak 30v across a 50 ohms

They are for a resistive voltage divider to allow both dot and dash paddle signals to come into the Raduino on a single analog-only pin: /g/BITX20/topic/7491087. -Neil N0FN

And Mine :) Red collection card in letterbox when I got home from work…now wheres the soldering iron? Charlie GI4FUE Sent: 11 January 2018 10:39 To: [email protected] Subject: Re: [BITX20] Micro-BITX

Here is a picture of the three resistors that was included with my uBITX kit. Joe Mnson WA4VAG

I am just getting around to installing the Ubitx into a case. I got it before Christmas. In my package of parts were 3 resistors. One, the required 4.7K. But there were also a 2.2K with red paint on

The raduino is the same across all radios. Only the firmware is different
