Nice!! Got some code to share? I especially like the large display. Not that it's 20x4 but that you chose a _large_ 20x4. None of us is getting any younger. To be able to see the radio without putting

I was going to suggest a Teensy. They come in the same footprint as the Nano and run at around 75MHz or so. Plenty of memory and LOTS of IO brought out to pads under board.

Sorry guys. My friend has been on the road so he hasn't been able to plot BPF's. Tomorrow we are getting together for a LTspice tute and plot BPF for 80 to 10. 73 Ken

Jerry Thanks for the suggestion of headers. Actually I did think of it but I didn't have any on hand at the time. I have removed all BPF components from the board. I made up an off board BPF for 40

if you want to push into dsp, it is best to directly get to teensy. we chose the 16x2 because it was the most easily, universally available display. i expect a number of people to scracth build this

Check out post 17339 in the AT Sprint Yahoo group. ?He's saying the Arduino environment is fine for simple things, but if you want more than that, best code from scratch. ? I've never messed with

As Jerry and Jack said, this is not exactly a cakewalk. Yes,it is a trivial matter to drive the display; there is basically one library to handle many different displays. This is true no matter what

OK, not that weird. I'm sure there's lots of bots crawling through these webpages looking for email targets to send spam to. ?And apparently both yahoo and groups.io decided to make that more

It did!? Thanks!

When I was Arduino playing a lot the DuPont jumpers used to hook everything up always drove me nuts.? It seems you never have enough of the colors, lengths, etc. that you want. I finally decided to

Weird, I assumed that truncation was a yahoo thing. And weirder still, when I search for "hfsignals" on the groups.io webpage, the message summaries show the entire entire email address without

I don't see how switching the display from 16x2 to 20x4 isn't trivial.? If using the normal hd44780 interface they are wired the same (and if you're ordering a BITX you should be able to handle the

Not sure about the setting, but the address is hfsignals@.... Marco - KG5PRT

I'm seeing a trunicated email for the order email address "hfsignals@..."? What's the last part?? Is there a setting to turn this trunicating off?

I ran across this and thought other Arduino players may find it useful. The Arduinos have EEPROM memory for non-volatile storage, but it's slow to write to and can actually wear out if written to over

John and gang, This is a DL vendor that I bought from - quite nice price! I bought 680 + 330 to make 1000pf for C91 and 92

Paid for another BITX40 and 2 Raudino's for the previous 2 BITX's I bought . Have had no confirmation yet of shipping ?:) VE7BEE

Quite a bit for many of the target customers. ?HFsigs is counting pennies to assemble and ship a functional SSB transceiver at $59. ? Fortunately it's easy to swap out the processor and display to

I think you're going to find out that it's not the flash memory (e.g., ~30K) that the real limiting factor. It's the amount of SRAM that's the real bottleneck. SRAM is used to hold all of the
