    There is a radio that is being offered that is quite a lot of pure and simple FUN; -It is the RS-918. It is SDR all the way! I have one, and it does far better than I'd have ever expected, The thing is small enough that it can be put into a large coat-pocket, and has a glorious COLOR display with pano-display as well as a waterfall. Highly customizable radio. It runs at ten watts of output 160 through 10 meters, all modes including FreeDV! There is a user group: -Search for these items, "RS-918" and "groups" and "io" to locate. Cost is well under $500. 73; Mike, K0JTA

    Hello! Your mcHF looks MAGNIFICENT!!! Very fine project that represents a lot of high-end SKILL! Yes, the RS-918m is a copy, but not too bad, actually. I had been told that then prices form the PC boards and the components is quite a total, lots higher than your $200 figure. -Then, a case of some kind must be made. Your ability to locate and collect the components is quite remarkable, as you were able to get your radio completed for $200! WELL DONE!!! Thank you for your link and the images of the progress! 73 from Mike, K0JTA

    Yep, the RS-918 is a nice rig. I looked at the the webpage ( http://s3com.net/0-RS-918/default.html ) and Mike's setup and testing certainly would be an advantage for the buyer. I noticed the groups io group is very active and lots of software updates happening. I think it's a rig I'm going to have a serious look at!
    Your mileage may vary,

    The problem is that the Chinese use poor-quality components. You will not see Amidon cores or high-quality capacitors and inductances in these radios. My radios case is handmade and it cost several bucks only. If you don't want to assemble one yourself it is better IMO to buy upgraded one here http://sp3osj.kooikerhondje.com.pl/eagle/index.html

    The RS-918 is a ripped off design of the MCHF

    If you buy one you are helping to rip off the designer
