Any amateur amp should be followed by a low pass filter suitable for knocking out the second harmonic and beyond. That means separate filters for 160m, 80m, 40m, 20m, 10m. You may piggyback some of

Steve, KD1JV has a knack for good code and user interfaces.? I have one of his short run of Slopbucket SSB/CW 20m rig.? Great radio and very solid user interface.? Fun build.? The code for it is

Several things... Those are switching converters and make noise.? Some can only go to barely 3A, most much less, the TX will want at least 2+A (at 12V) or more.? At 80m and 24V expect 3 to 3.5A

Most of us spend too much on "just a hobby".? I try to be frugal and get the best bang for the buck or whatever. It is why the junk box to end all is my mainstay.?? Can't solve all the problems,

I have seen some of these come with 30mhz LP filters and some order the model without a filter and add one for the band they will be using.? Is either idea acceptable or is one better than the other.

Looks nice.??Perhaps pin headers for audio derived AGC add on, pin headers for de click add on, pin headers for VOX add on. Nice to have test points, I make them with a filled pad and silk

Version 4 has a socket for the Arduino so that was not going to be so bad.? I bought the RobotDyn Nano.? It turns out that the headers are on the opposite side as the one that comes with the

I zero-beat. This beatnote thing wasn't well thought out, you want to move the BFO too, far enough to avoid hearing the opposite sideband. Left as an exercise for the reader.

Don't use it much either, I also find it cryptic. But it's very handy in macros, the *..h files are full of the ternary operator. I'm a luddite myself when it comes to a fancy user interface for no

You could use a 50mhz reference, but you would have to hack the Raduino code a bit. Something like this should work, as per post? ??/g/BITX20/message/35235 In my own Raduino code,

While doing other things I realized I needed one IO pin for a differently arranged user interface. Looking at the relay tree it is notable there are only 4 used states and one that is don't care. That

Allison, unfortunately, it’s not so simple for those of us who live outside the USA. We simply don’t have the luxury of being able to deal easily with the likes of Mouser, Digikey, RF Parts, etc.

I ordered it Monday and it arrived in NW Florida today. Let the fun begin? -- Mike AI4NS

Thanks Jerry, Its one I never use as it make code less readable.? As a result the brain locked. It was just to cryptic for me. For a test I did try digitalRead() and two things happened, it works,

The ternary operator has been around since the 70's ? ??https://en.wikipedia.org/wiki/%3F:#C This equivalent (but untested) function might be easier to read. // Returns a value of 0,1,2, or 3 // If

byte enc_state (void) { ? ? return (analogRead(ENC_A) > 500 ? 1 : 0) + (analogRead(ENC_B) > 500 ? 2: 0); } That's the code from the UI section...? My brain does not want to parse it. Best I get is

All I have a 50mh signal source, can I use it to calibrate the v4 ubitx board? Thanks John KD0MOA

Awesome thank you for the update. I now have my Teeensy funds are tight so more time to get the cash together is not a bad. Tim, M0THM

No thanks, I like that my uBITX is small and don't have any need for a lager screen nor do I want to change enclosures.? Right now I'm having a blst with it on CW.? SSB on the uBITX is not important

Bill, Here is a link to one of Ian's pages which describes it. Once you go to it you won't go back. Ignore what I said about it and the s meter. You are on the right track.
