Also copy many time KC8WKB calling CQ, answered a few times. Calling CQ, no answers. Also 9:29pm ET, heard AA4PG KM4YEC Craig

Could hear KC8WKB calling CQ, but the two Spanish speaking QSOs going on on 7.180 and 7.175 made the communication impossible. 73 -- Ion VA3NOI

Just released raduino_v1.11. Download it from https://github.com/amunters/bitx40 ( https://github.com/amunters/bitx40 ) New in this version: - added menu beeps (needs CW sidetone to be wired up) -

Hi Allard, I have boldly placed a link to your Github repository on the wiki in two places (I think it's worth mentioning twice!).... and included your wiring instructions and pictures for the wiring

It goes 0 to 5V.

Hi Dale,? Yeah true. I'll keep an eye out for some meters. I have a homebrew antenna tuner that I just tune by ear as seen on a YouTube video. Works fine. Plus my antenna is built for 40m so it's

Listening right now and 7.178 MHz is better, or even better 7.1775MHz. There is a strong station working on 7.180MHz and another one on 7.175MHz -- Ion VA3NOI

Measure that tuning voltage (to ground) going into the Raduino as you rotate that pot through its range. ?Voltage should smoothly change from 0 to 5 volts.

Hi Jerry, thanks for reply. Well, it is a little bit tricky to explain. I'm sure that both 10k lin and 20k 10-turn are good, both wired properly. Sketch was also good, Allard's 1.10. I cannot

With PTT pressed and key not closed, this is like an SSB transmitter with no audio. ?There will be some residual carrier, since that balanced modulator is not perfectly balanced. ?I doubt this

I don't fully understand the symptoms you describe, but: Those 10 turn pots can have funny pinouts. ?I'd take it out of the circuit, check with an ohmmeter. ?Make sure you have identified the

I tested most of the features of v1.10. This is what I did: 1. All toggles works fine. 2. Installed 20k 10-turn pot (the only kind of 10-turns I had ATM), it looks much better than 10k lin. It

Alternatively you can use: pinMode(FBUTTON, INPUT_PULLUP) and eliminate the digitalWrite line. Mike K5ESS Sent: Sunday, May 14, 2017 10:00 AM To: [email protected] Subject: Re: [BITX20]

Larry & Gerry, I've added your posts to the wiki under the modifications / improvements / hacks section. -- 73 de Noel, ZL1NC

In the latest sketch version v1.10, frequency update is completely disabled while transmitting. To use this feature make sure you have the PTT SENSE line installed. See

I tried out a different microphone, but still receive poor audio reports.? My next step is to get a usb cord so I can update the sketch.

There are files on the bitx20smd at /g/BITX20/files/M0ZHN%20smdBITX ( /g/BITX20/files/M0ZHN%20smdBITX ) This was available about 6 years or so ago but now you would

As of Arduino 1.0.1, it is possible to enable the internal pullup resistors with the mode INPUT_PULLUP. Additionally, the INPUT mode explicitly disables the internal pullups. So the digitalWrite

You're welcome. The hand book can be a source of a lot of info. on contruction. I might aid that I'm planning on going that slightly heaver wire for power. WA9DOH PS I hope be on 7.179 there about at

Mike 4X1LM The original BITX20 is getting rather old. After several thousand posts there may not be much more to be said about that design. There are still kits available for BITX-xx transceivers,
