      Hi Bob and group
      I made a similar comment when Pete the N9 call stated his adds on this reflector a little while ago and got short shrift for one or two other US calls.
       
      Pete I agree with Bob that this not the appropriate reflector for a hard sell business. Good luck with your project. As they say on E-bay there is one born every minute. No one on this group is here other than to promote the advancement of SDR radio in it's simplest and most basic level. We are fortunate in having trusted radio amateurs who put a huge amount of personal time, knowledge, skill, and down right good old amateur radio spirit in designing and kitting these great SDR radios for us at a cost that is frankly laughably cheap.  I would guarantee that nobody here whether a designer, beta tester, kit provider or builder of kits for others make a serious dime out of it. Strange but true!

      Now can we get on with the serious business of discussing Softrock SDR and helping ab anitio kit builders.

          Pete old chap, I don't in any way object to your product. Infact I wished you luck with it. Surprising as it may seem coming from a Brit where the entrepreneurial spirit is frowned upon nay stamped on with high business and employment taxation. I am very much in favour of innovation and product development and making a buck!
          IMHO my one and only objection is to promote and discuss products and innovation that are not appropriate to this reflector / interest group which is primarily about Softrock SDR radio hard and software kits and applications at Amateur level.

          If the majority of the group feel otherwise then who am I to set any kind of rules. I am personally in favour of a freewheeling association as it has been up to now. The amount of development that has been achieved here is a credit to the main players as I said in my last missive.

          I feel privileged to have been able build and learn about Softrock radio with this group. It has brought back a lot what has been missing in Amateur radio in recent years, giving a feeling of achievement, sharing ideas and help, plus getting a great radio integrated with PC technology which has amazing performance for peanuts. It's about a modern approach to Rolling your own and not buying Taylor-made.
          I hope that clarifies my position.

          GL es 73 Pete M0fmt.

            Bob,

            Since I was the one that made the "just plain crazy" suggestion to a SR newbie in that last big go-around about solder paste, I'll dispel some of the complaints about alternate soldering techniques.

            First, I've soldered regularly for over forty years and actually had formal training in soldering in my early years. I WELCOME the solder paste technique because the results are astounding and the process is extremely simple.

            See http://SDRbuzz.com/images/gallery/SMD1.jpg for an example...

            I soldered the SMD components on this board a week ago. It took me no longer that THIRTY minutes from start to finish. Notice the quality. Compare that to any of the iron soldered examples posted anywhere. The connections are literally perfect. It looks like a production soldering job.

            The solder paste technique is very inexpensive. I bought a $5 (.5cc) syringe of paste and have built several SRs with it. The syringe still looks as full as it was the day it arrived. The other tools are also very inexpensive. The embossing heat gun cost me $20. I'll be using it for a lot of things not related to SR. The cup warmer... well I already had one, but they're just a few dollars new.

            "Elaborate"? "Perfected"? "Disasters"? My first board required fixing a solder bridge and I also had one capacitor turn on me that had to be re-soldered. That was a very shallow learning curve and those are hardly disasters. Since then every board has been perfect.

            So unless you've tried it, don't knock it...

                Very neat job. The syringe I have put it out in blobs rather than as you
                would expect toothpaste to come out, so I haven't used it. I have
                another syringe I hope to try on the Mobo 4.3.4 kit when it arrives.

                    I am one who has tried solder paste once and failed.
                    The point is that the first Softrock most people build is a Lite. $15, a few
                    easy to solder SM components.
                    You are saying to newcomers, "You have spent $15, now spend $30+ and a few
                    weeks to solder it."
                    I do not think anyone has said "Do NOT use solder paste" but I am one that
                    feels it is not neccessary to ask a newcomer to learn a new technique when
                    the majority of Softrocks have been adequately soldered by hand.

                    You have the equipment and experience so it is a half hour job to you. For
                    someone to setup something like you describe it might take a week to do
                    research and source the materials. Outside the US (many of us are!) I do not
                    know of a source of suitable paste with reccommended dispenser. That means
                    if we get it from USA it may have been cooked for several weeks in hot vans
                    and warehouses. Paste was my downfall.

                    I'm just happy to get something working. I don't have to give someone a
                    magnifier so they can see the soldering is bad!
                    The process is simple to you because you did get everything right the first
                    time. No doubt I will try again sometime but only when I am ready!
                    Setting up a solder station is an investment, many Softrockers may go on to
                    reflow techniques but I have not found it as simple as you say.
