We had some problems with the phono plugs, cause of the construction on the radio.. So we had to use our Dremel-cutting tool to cut off some of the photo plug to make it reach all the way into the connector in the tranceiver (see pictures). We also managed to fit the interface into the cover of the 9-pin D-Sub. The trick to fit it all into a pre-drilled board (vero-board) is to use smaller components, with smaller body and legs. The holes on the pre-drilled board are quite big so I managed to fit two components into a single hole. Actually, there is plenty of room left. When we started to build we where trying to make it as compact as possible, but when we where half-through we saw that the space where no problem what so ever ;) You can almost build two sets and fit it into the Clamshell ;) I've used a ordinary telephone cable with rg-15 connectors (the rg-15 connectors where of course removed). The cable consists of 4 cables, only used 3 of them .. The black one that you can see on the photos was mounted to GND just for supporting the cable, it is not connected at the phono-plug end. Again, the biggest problem was to get the phono plugs to get all the way into the tranceiver. So, be careful when trimming/carving the plug to make it fit. We used a Dremel tool. There might be plugs available in market that fits directly, I'm not sure. We also connected pin no.6 and pin no.4 together on the DB-9 to make the interface not depending on the program to make RTS. This is not nessisary to get it to work with the MCP programs, but we thought it whould be nice ;) Here you go, the pictures are hi-res. http://alpha.tuben.lugn.nu/~tuben/iface For Swedish (Scandinavian users) I have bought all the components at ELFA (www.elfa.se). And managed to keep it all under 100 Swedish Kronor (cable excluded) (~$10). The clamshell part no at Elfa is: 44-093-55 http://www.elfa.se/elfa/produkter/se/20/2006581.htm and the Elfa part no for the DB-9 is 44-056-01 http://www.elfa.se/elfa/produkter/se/20/2018978.htm#_44_056_01 BR, SM4XDJ Torbjörn Sweden. torbjorn.soderberg@fro.se
The NorComp 972 series from Digikey looks similar. The Newark Catalog shows others including Cinch DE-51218-1 (Newark 45F990), SPC Technology 8335-0243 (Newark 16N6957), and ITT-Cannon DEBS9 (Newark 93F8859).
I have not verified any of these but they look like they might work also.
