Bob, The "old" board works well.? You will likely be happy with its performance.? There are some mods and kits for mods available to fix the few minor issues that may or may not bother you.? If you

Hi, Richard, I have a recent spare that I will not get around to for a long time. Completely unopened. Prirce is the same $109 by paypal to " *jean (at) g2ideas.com* " I will ship by priority mail to

Good news... bad news.? I just received the "old" board a few days ago.? :-(?? Will there be a retrofit parts list and modification instructions?? This would greatly simplify the process for many

Hello? Maybe a simple solution with a NE567 as a PLL FM demodulator / synchronus AM detector will be ok in order to keep the cost and the complexity of the circuits down.

That seems to be the standard response from Chinese suppliers, Vince. I encounter it on just every occasion. It seems to be spreading too. I had an Australian supplier ask for a photograph of

For 6m (and up) you can use the DXrobot to monitor the band condition and to efficiently work DX: http://www.gooddx.net Band status alerts are also sent via Twitter: https://twitter.com/dxrobot And if

Maybe in Europe works a little bit better. In May and June we know bands may be open and some people try to call. Also are very important the beacons. TEP is another story as I found it open in

Those pullups to 3.3v for SDA,SCL are already on the Raduino board so the Nano can talk to the si5351. All that is needed is to remove the 5v pullups from your i2c display. If it's an LCD display with

If there's still a digital pin free on the Nano into a counter-timer, that could be used as the frequency counter But I grew up on bad receivers that were good at letting me hear both sidebands and
