Well, getting back on topic, could you say whether you want to acquire a GDO working & complete, build one from scratch, or might a kit be of interest? I mention the latter because I believe that there has been a kit recently available from a German ham which has been highly rated, but I don't currently have a detailed knowledge of it. Of course there was that kit from Ambit which was very popular (G3
), but they are probably now collectors items.
I wonder why the Maplin GDO is so disappointing? Something I note about the Model 59 are the large coils; something around 1" diameter on what looks like a good grade material (polystyrene?) and no ferrite slugs in sight. That style was maintained on the later PMR-10. Comparisons with an HRO coil-pack spring to mind. In contrast, most modern GDO's usually have quite small coils. It's not hard to believe that the coil design of a GDO matters appreciably.
