W9TS and K7IC and others have reverse engineered 99% of the Syntor X's code plug (http://home.xnet.com/~pakman/syntor/syntorx.htm). The reason I say 99% and not 100% is that KB8ZQZ discovered that some non-Motorola radios (specifically his Yaesu VX-5R) wouldn't decode the DPL generated by the Syntor with bits 0->2 of byte 5 set to all ones as documented. He also discovered factory programmed code plugs that didn't have the all ones setting. By experimentation Dennis found the bit settings that worked with his Yeasu and incorporated his findings into his excellent syntorxgen program (http://msuarc.egr.msu.edu/syntorx/). A lot of codes worked with more than one setting of the "funny bits" (what Dennis calls bits 0->2 of byte 5) and he picked the one that worked the best on his HT for his program. This is were I came in.
I'm in the process of adding DPL support to my xcat project (http://groups.yahoo.com/group/xcat) and I used Dennis's code as a base. Unfortunately on the air testing was less than successful. The first code I tried (365) worked fine, but the second code (245) failed to be decoded on an Vertex 5000 repeater with a Pacific Research controller. After some head scratching I tired changing the "funny bits" and found that 0 worked. Dennis's table (http://msuarc.egr.msu.edu/syntorx/dpl_sparebits_data) showed that 0 also worked with his Yeasu. The documented all ones setting for the funny bits did not work either. So here's the pitch: Is there anyone that has access to a suite case programmer with Syntor X support that is willing to generate some test plugs? I'm interested in documenting the "golden" setting of the "funny bits" as generated by mother Motorola herself. Hopefully this information will allow code plug data to be generated that will work with radios from other manufactures. Dennis's testing confirmed that the bit patterns in factory generated DPL code plugs he's seen were decoded successfully by his Yeasu. I don't need the code plug themselfs, only the data pattern generated. If you have the equipment but don't have a code plug I'll give you one. Thanks & 73's Skip WB6YMH p.s. I apologize for cross posting, the other lists I posted this message to have very low traffic, but are specific to the Syntor audience.
