  • MD kit from Bulgaria

    G'day,

    Has anyone here previously bought this ( http://tinyurl.com/SNIFFERXR71 ) kit? Any comments would be appreciated ... is the Bulgarian company, that is selling it, legit?

    Regards,
    Rob (RKC)

    Well they are on ebay with 100% positive feedback

      I have one of these in progress. (I've taken a long break but expect to pick it back up in a week or two.) I dislike this thing for several reasons.

      All the pots connect to a header at the bottom middle of the board. There aren't enough pins to go around and one pin has three wires connecting to it. The header is a PITA and difficult to wire without damaging.

      The TX output connector is at the bottom right. Why would somebody want the output on the front?

      The MOSFET mounts in holes that are barely wide enough to fit the pins. If you ever have to replace it you will very likely rip the barrels.

      The damper resistor provided is 1/4W, and that is what the PCB was laid out for. (I think that using a 1/4W damper resistor is slightly ridiculous.)

      The 1W resistor supplied for the preamp input does not fit in the 1/4W space provided.

      It appears that the mounting holes for most of the components are unnecessarily tight. There was plenty of space available to allow for larger pads/holes.

      There are no holes drilled for mounting. It would be wise to take care of that BEFORE mounting any components.

      I never got to see the instructions that came with the kit (components were mounted by someone else) and so I don't know what magic was supposed to happen with the header and two resistors I mentioned, but I think those are some serious defects.

      Somebody buying the kit on Ebay probably gives feedback BEFORE building it, so feedback would be for the delivery and not necessarily for the quality of engineering. Eh?

      Maybe I'm just picky but I would not recommend this kit.
