EFJ 5100/5300 Out-Of-Band modification of the PCConfigure 2.10.02 software Good news, everyone! I have gotten my brain cooking on these EFJ 900 MHz radios that have become cheaply available of late, and since they seem to play very well in the Ham bands, I have figured out the mods necessary to get the software to allow out of band entries for UHF Low, UHF High and 900 MHz models. The others (VHF and 700/800 MHz) did not seem to require any modification for Ham coverage, AFAIK. Replace the band table occurrences of 450 with 438, 470 with 485, 900.9875 with 910.9875 and 935.0125 with 925.0125. Data types are both 32-bit float and 64-bit double. 4 Band Tables Found At: 0CA714: 0D22D0: 201C7C: 206CCC: Patch points, showing old and -> new data: 0CA720: 00 00 EB 43 (470) -> (485) 00 80 F2 43 0CA724: 00 00 E1 43 (450) -> (438) 00 00 DB 43 0CA770: 66 66 66 66 E6 27 8C 40 (900.9875) -> (910.9875) 66 66 66 66 E6 77 8C 40 0CA778: 9A 99 99 99 19 38 8D 40 (935.0125) -> (925.0125) 9A 99 99 99 19 E8 8C 40 0D22DC: 00 00 EB 43 (470) -> (485) 00 80 F2 43 0D22E0: 00 00 E1 43 (450) -> (438) 00 00 DB 43 201C9C: 00 00 00 00 00 20 7C 40 (450.0000) -> (438.0000) 00 00 00 00 00 60 7B 40 201CA4: 00 00 00 00 00 40 7C 40 (452.0000) -> (440.0000) 00 00 00 00 00 80 7B 40 206CDC: 00 00 00 00 00 20 7C 40 (450.0000) -> (438.0000) 00 00 00 00 00 60 7B 40 Note: Since I don't have any UHF 5100's I haven't fully tested the mod on them, but on 900 MHz I can confirm it works great!
