Re: Troubleshooting node 1642

Hi Ron,

I replaced my 10 year old 800 MHz Ingraham HDD with an Intel DM2800MT and a Samsung 120 G SATA SSD. I thought about the Pi but I wanted to go old style.

eBay has the boards starting as low as $35 US. Not too sure what shipping would be to Canada but it's a good start. You do need to get a parallel header ribbon which attaches to the board for your IRLP card.

well then I guess the software dates it :-) The mini-ITX board
would date it too, but more telling is the IRLP Board manual dated
January 2006 for boards version 3.0X. The computer supports a flash
card memory (not a hard drive). I'm thinking that maybe one of the
board capacitors in the audio output has gone open.

I own and maintain the node personally and it is linked by radio on
a 222 MHz link to the local repeater. Or it was. A replacement would
be at my own expense. The IRLP board (connects to the printer port)
itself seems to be OK, I might cut costs if it could be kept.

How old is your node? aumix has not been used for years. The tool for audio is �alsamixer'

audiotest again gives a very low level of white noise during the test.
I suspect that the mini-ITX board audio section has a problem. It is
an Intel DG945GCFL and it has run flawlessly for a few years, if it is
the board can I find a replacement with a parallel printer port cheaper
than I could switch it over to a current Raspberry Pi system?
