Robert Already have two of these boards. They are very convenient for the experimenter. Just be extra careful that you don't inadvertently connect ground or Vcc to where if is not

Jerry you know the uBITx PA design is nothing like the WA2EBY design, so why would you expect the same result? It escapes me why people bring this up. The commonality is that they use the same PA

... and if you don’t want to solder the tiny CP2102 chip, you can get it on a board, with everything you need to hook it up to your Arduino for $2 at

All: Yesterday morning I had a lot more hair than I have today. I'm working with a KY-040 encoder which has a switch built into it. I'm also using a Teensy 3.6 instead of the Nano. The encoder has 5

The description on-line specs it for 3.3V boards.? Is the one you are referring to different?

Opps...I misunderstood the problem. Jack, W8TEE

I believe Dave has identified your problem area, if you wired up your mic jack per the wire up instructions your Kenwood/ Beofang mic won’t work. That mic has the audio/bias on the ring and ground

I did Howard's mod by adding the calculated 27uH inductor in series with R86 and parallel caps of 220pF on R87 and R88. My power output change results: 7MHz from 12.5w to 14.5w 14MHz from 7w to

If D0 and D1 come out to a jack for the keyer paddle, can use the same jack for firmware downloads.?

Could be that the Raduino's processor just gives access to the RX/TX UART pins, no USB chip on board at all. Then use your choice of FTDI/Prolific/SiLabs in a cable adapter such as this:?? ?

Ian, I'm marveling at your code! Fantastic. I had seen your note about 5 hex files being available and I couldn't find them. I was having problems with the source and couldn't upload them. Hence the

Thanks so much Jack. I've often needed that info for other projects! I printed it out fo keep. However, I was referring to Ian's precompiled hex files I couldn't find, because I was having trouble

Like I said, most of the cooked IRF510 reports seem to be from twiddling bias pots, not high SWR.? Can you point to a few posts that report otherwise? When operating at 12v? Of course there aren't

This is a board from eBay that I find very useful when trying out various projects using the Nano. Nano plugs in and there is access to every port pin and adjacent to each a 0V and 5V connection

This in a nutshell. While macOS may have issues with CH340 chips, Windows users tend to have issues with both FTDI and Prolific chips (in both cases, the market was flooded with cheap, cheerful and

By the way you have not stated witch BITX board you are testing. If it is a SMD version from Ashar Farahan then you should do the carrier shifting mod suggested by VK3YE Peter Parker by witch you will

Tim Just disconnecting the microphone sometimes does not reduce incidental noise in the audio spectrum enough for a good measurement of carrier balance. This is especially true if using a microphone

“Exactly where did you find this data?” Right here on the forum. Multiple reports of IRF510 failures. Not a single RD16HHF1 failure reported yet (now that doesn’t mean it can’t happen). My

Satish, No mic. Just the two-tone generator. When I get the rig put back together I'll try isolating the mic pre-amp to see if it is generating some kind of noise. It doesn't look like noise on the

Virtually any RasPi will do that, and most will run software equivalent or better than 'doze stuff for operation.
