?I sure do appreciate all the efforts you/others have made. I downloaded 1.24 a while back and it made night and day difference in my bitx40!!! (versus original stock software). gordon gibby kx4z

12V *anywhere* on the Nano will destroy it! Well that’s not strictly correct. There is one exception. Although it’s apparently not connected in the Raduino configuration the Vin pin on the Nano

The Raduino uses the si5351 clock generator, outputs from si5351 have just a series cap where they leave the raduino. Datasheet here: ?https://www.silabs.com/documents/public/data-sheets/Si5351-B.pdf

There is a also design of BPF with lower losses. Have a look at http://www.wa0itp.com/bpf_bandpass_filters.html Happy bitxing Bhatnagar VU2SPF

Hi, I've just released raduino v1.26, download it from https://github.com/amunters/bitx40 ( https://github.com/amunters/bitx40 ) New in this release: * Rearranged the menu structure, skip menu items

Has anyone tried modifying the WSJT-X software to invert the tones so that e.g. JT65 transmissions on LSB are equivalent to ones on USB??? -Dan Fay

I was wondering what the output of the Raduino is?? In particular is the output enough to drive an SBL-1 or an ADE-1 between 7 and 28Mhz? Any info greatly appreciated.? ? Ian.

12V *anywhere* on the Nano will destroy it! though the A... and D... leads are the most susceptible. D7, with C130, is *supposed* to be a snubber for K1's back-emf on release of PTT, but is only that

Just a few minutes from the time you posted the above about hearing some digital, I was pumping some digital at 10 watts, from the bitx, your direction. It makes a fine data radio too. Who knows, you

I use M3 Nylon and Brass spacers, nuts, and screws from Amazon and have had absolutely no problems with them. I look for a vendor that allows a selection of both sizes and lengths so they all come

Peeps, Given the large number of mails, i much like manh others tend to skip mails that have subject lines like "issue" or 'my problem'. It would be best if the subject line describes the problems as

You can do multiband quite simply with juat two sets of filters : 1. Make on set tunable from 14 mhz to 30 mhz with a ployvaricon or any two section broadcast variable capacitor. 2. The second

Ok it's clear now. Thanks for the help I have a lot to learn. When I get a chance I will change that diode and try again.

Thank you for the advice. I already have a bunch of low pass filter boards from kitsandparts a few years back, so just need the bandpass units. I was looking at the qrp labs board, so that may be the

Hi, Over the months I have published a number of minimal hardware mods that are required for certain added functionalities in the Raduino software. I noticed it is sometimes confusing and hard to

Looks like D7 is a snubber diode for the relay K1. There's also a snubber diode D8 on relay K2 (near the blue trimmer RV1).

The Raduino has a 5V regulator to drop the voltage for the Nano soldered in. Raduino takes the same 12V that the BITX40 takes but brings it down to 5V. By mistake if you connect or a oops moment put

Thats confusing unless I'm missing something. The wiring diagram shows +12v to orange wire on raduino and black to ground
