Hi all I love the Frank K0IYE "Crystal sets to sideband" book and I was the first to host it online, at my website see http://hanssummers.com/k0iye.html though it is now hosted in several places and

What version of the bitx are you using and NO the IRF530 is not a good match from what I have read there is an inbalance in capacitance. The heat sink is not to be at ground potential it is at

I cannot use my bitx for transmission. while pressing PTT the connection wire to IRF 510 burns. I think a short connection somewhere, but we couldn't identify it. Reception is OK. we have changed the

Have you upped the size of the heatsink more power=more heat you need a good radiator to keep it as cool as possible. I have a cpu heatsink and fan on mine at 24 volts I get 15-20 depends on the band

That's no so simple, BTDT, or is it? 1 - You need to put a big capacitor (> 470uF in my case) on the +5v to the arduino. 2 - You need to decouple the +5v of the LCD backlight LED from the +5v of the

That's exactly what I'm baking in my kitchen oven now (hi, hi, hi) no ready to test yet... as soon as I have some working code I will post it on the list/github. A sketch with feature segmentation via

When you report power output, do you report the peak or the middle range that you see while speaking?

Running 20 V on the PA jack, I had a short 1 minute transmit QSO. The report was that the signal was strong but with some audio distortion. I touched the heat sink and it was hot to the touch. My

Yes, I would also concur. It appears that the most up-to-date location for “Crystal Sets to Sideband”, is Frank’s site at: http://www.qsl.net/k0iye/ The latest revision is 14. 73, Dale K9NN

I agree. I bought my copy of EMRFD a long time ago and started reading it. I felt like a two-year old trying to compete in an Iron Man competition. For me, it was a walk-before-you-can-run issue. Each
