add a 10k resistor in series with the diode. it prevents the agc from gulping. - f wrote:

I sort of fixed the problem. First I found my offset (-150Hz). That means for a signal of 7.125MHz I had to adjust at 7.12515MHz for zero beat. Then load the sketch into Arduino IDE and look for the

Hi all, I have redrawn VU2ESE AGC hand sketch schematic. 73 Gian I7SWX

The PA-09 crimps mentioned above are PRICELESS for these connectors. I tried a cheap pair of cheaper crimps and they were garbage. I highly suggest the pa-09. I picked mine up from adafruit a long

Ion, I have experienced the same problem, but somehow got it to calibrate on the 10th try. Joel KB6QVI

Hans, That made my brain hurt:-) Joel KB6QVI

I don't have a problem compiling or uploading any sketch (you just go in Library Manager and change the version of the library you want to use). My problem is that, regardless of the message on the

Nope catered for in the loop.? Ignore me ! Rob

Ion, The sketch is now wrong. Doh! I just checked the library details again.? They have changed the way calibration is done, it now has a one time set?? " si5351.set_correction(value) ; "?

Hans, I'm impressed. Thank You MAc sp9mrn

During the first setup I have calibrated the frequency readout. The behavior was as described. Connect A2 to GND - message on screen "Calibrate". Keep holding A2 to GND rotate the tuning pot for

Following possibilities are to be considered. We can divert? the back-lit circuit of LCD to unregulated voltage with higher series resistor. The datasheet for7805 indicates around 3V . Now we have

So, last night I did some meaurements. Room temperature at 18 °C. LM7805 goes as high as 52°C with 13.8V at power feed. Temperature drops to 49°C when at 12.8 V (that is the votage of a fully

?I already did this. Doesn't change anything. Do you think it is possible to buy just the pcb with the nano on it? Don't need a 2nd display. If yes, what would be the difference in the price?

I found this helps when fault tracing.

A document of tips for testing.? I have waveforms for receive and transmit.? Not mine but gleaned from the net.

Hello Don, Does your kit look like this It's known as the Hendricks BitX20a kit.?? This is the one I have and modified it to work on 40m.? It's a great kit but it is very very touchy about the

whoa, hans, what an incredible find and a neat hack. i tip my new pluto 937 with programmable tempurature control to you! ok, who's first to crack this hack? - f
