https://forum.kiwisdr.com/index.php?p=/discussion/comment/18595#Comment_18595 In my case, yes GPIO.

No it was away from the header pins. I told you, it was a through board connection, which would've been flow soldered. These sort of connections are prone to bad joints on any multi layered PCBs. Having the BBG in the V1 for comparison readings made…

I have reassembled it all now. When I dismantle it to connect the Antenna switch I will take a photo then. But there really won't be anything to see as it wasn't visible to the naked eye, only to my bench test equipment. There was a through board c…

Okay issue corrected. There was a high resistance through board solder connection on the Beaglebone board on one of the 5v rails. I don't foresee any further issues now it has been corrected, unless Beaglebones are prone to bad assembly issues. Are …

No, not using a relay board with the V2. I don't beleive you can't access the 5V/5VE pins without full disassembly of the V2. The PSUs (there are two one for each of the V1 and the V2) are professionally custom built linear 3.5 amp with toroidal tra…

Problem resolved.

I'm using the Beagle GPIOs and a switch board with opto isolators from Amazon. It draws very little current (trigger current 5ma) and and can be set to active high or low on input. It needs no extra components other than some BNCs. I boxed it up in …

I have to build the new switch, so will see who gets there first.

Notified of Shipping on the 4th, estimated delivery on the 12th. It arrived today the 8th at 10 am. Connected up, configured and updated without a hitch. Online and first 'customer' within the hour. Was just about to install the ant_switch extension…

Okay, thanks I guess. Question, why doesn't the forum search return that?
-
Yes agreed that would be ideal.

I found unsticking the fan from the PCB and sticking it instead to the side and bottom of the case stopped all the noise. Only slight air movement noise now.
-
Okay I have reduced the noise level. The instructions for the enclosure tell you to remove the foam tape from one edge of the fan otherwise it will be too tall to fit between the Kiwi board and the enclosure base. But this allows the fan to vibrate …

I notice the fan is 5 volt but is supplied by the 3V3 supply. I take it that isn't an error? Barney
