Hi I've spend a little while trawling the messages here, and I'm struggling to see if anyone is currently offering kits for sale? I'm in the UK if it makes any...
Just remembered to look at Andrew's proposed calling freq. list and the new ARRL band plan list on my wall! Do these look OK for digital & SSB modes if one is ...
I understand that the SoftRock has been used for PSK (PSK31) and RTTY, but what about other Digital Modes, please? -- Thanks! & 73, doc, KD4E Have a joy-filled...
I'm confused (again) ..........just a few questions rolling around in my mind. The thing which really confuses me about the 3 OpAmp Single INA163 is the "Input...
Is there a list of soundcards that work or are acceptable or better yet should be avoided. I tried searching for a card that I had picked out but couldn't find...
Good Morning All, There has been enough positive response concerning a new FET PA board for the stack version, (alpha version), of the RXTX that I am going to...

I've posted a couple of pictures of SoftRocks in a Bare Case #1 from Hendricks QRP Kits. http://www.qrpkits.com/barecase1.html By using Molex pin holders, I...
Good Evening All, This evening I did a layout on the push-pull output stage for the stack version of the RXTX. The board is 1.5 inches by 2 inches and...
Hello, I have been receiving signals using Rocky and have noticed that it doesn't have much ability to display signals which are not above the noise and ...
Hello All, First of all the best wished fot everybody for 2007 I have this problem that image rejection in my just build V7 softrock is not very good only...
