Portsdown 4 / Langstone Rx selection

[g4saq]

Colin, thanks very much for this information. I had naively thought, on the basis of the "List of GPIO Connections" that no action was required to set up the pin. I will experiment with the menu settings tomorrow to find the best solution for me and I shall report back here so that others can see the outcome. Thanks again! Russ.

Hi Colin, I'm afraid that did not help me. In Langstone Rx mode (145MHz), I pressed SET and then scrolled through the menu until I got to "Band Bits (Rx) = 00000001". I changed that to 00000111. That did not put a voltage on GPIO breakout D7. What it did was to change the 8 band decode LED to position 7. I wonder if you are able to assist me, please? Thanks, Russ.

Hi Russ

As I understand it, you'll need to set the Band Bits to 10000001. It's that first (most significant) digit that is D7.

Dave is correct, the left hand bit is bit 7.

The 8 band decode board will respond to the right hand three bits.

So 10000001 will decode as band 1 with bit 7 high.

Colin.

Dave & Colin, HOORAY! Thanks chaps, it works now. I was beginning to think I had fried the pin. As you will have gathered, I was entering binary 7 instead of setting bit 7. Oh well, all's well that ends well. Best wishes, Russ.
