I have to agree Alan - the best way to do this stuff is learn and do it yourself. But we need to recognize that this may be mumbo MOJO to semi-technical hams. This is perhaps the hardest adaption when working with SDRs in a group like this if you are not mathematician and/or an engineer. The chat can get very heavy at times and sometimes I find myself groping for answers and the answers are not intuitively easy to understand without the proper background.
For the non-engineering techy going from a crystal controlled SDR to PIC controlled frequency agile oscillator is one heck of a big leap in technology - so I can understand the turmoil in their thinking and a lot of the builders are saying what the heck did I get into. Many are excellent builders (they would not be here if they were not) but are not in to pushing the design envelope and thus must depend on what others are developing. The other side of this is the technology of controlling devices with PICs - if you read all the threads there is several different approaches being used to program PICs and it can be confusing to thinking when one must consider what the other guys are doing and what should I do and how do I do it. We opened Pandora's box by introducing the devices like the Si570 and the world of PICs and it is good that a few designers are very patient and trying to hard to keep up with everyone's wish list. I personally want to thank all of the contributors to this new phase of SDR's who have donated their skills and time. This is a very technical group and we are working on the edge of technologies grabbing things off the vendor's shelf almost before the device is a common market item - this is a demanding science and it takes a lot of contributors to do these quantum leaps in a few days. Thankyou, Thankyou, Thankyou to the designers and to the builders/users who keep coming with good ideas and challenges - this is a great group. 73, Ray, N0FY SKCC 3704 FH 997 _____ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Alan Sent: Friday, May 09, 2008 11:16 AM To: [email protected] Subject: Re: [softrock40] v8.3 Lite+Xtall kit details ----- Original Message ----- From: "Tony Parks" >The center frequency numbers may be adjusted to a custom set. We will try >to support those requests soon. I suspect with an infinite choice of frequencies from the Si570 everyone will think different. Single band, all bands, 48/96KHz, utility, broadcast etc etc. I'm not sure we should ask the developers to make too many options. I am looking for the things I can't do like circuit and software improvements. I found that learning the simple PIC programming far easier to than all the other things about the Softrock. I encourage people to try. Like Paul I offer to program PICs if my costs are covered. There must be others in the group who can do this. Thanks for everything Tony 73 Alan G4ZFQ
