Alinco DR-M06, Old TH and new T / TH mod for full TX/RX Due to various revisions of the radio's display board (this is where every mod refers you to) you will find many differences in board layout and design with no easy way to distinguish between revisions. If you look on the Alinco USA website, they state that you can get the appropriate mod faxed to you if you provide MARS/CAP documentation. For the rest of us, once you determine which mod fits your radio, be sure to solder so that both halves of the point are connected (does not take much solder) and take care not to over flow onto other nearby solder points As you can see there are several mods for the DR-M06 radios available. I recommend that you have de- soldering tools handy before you attempt them. For all mods: 1. Remove both top and bottom cover plates 2. Remove VFO knob, Volume, and Squelch knobs 3. Locate plastic tabs on faceplate and lift them over the securing posts (two on each side of case) this will enable you to remove faceplate, but you may have to lift tabs several times to complete. 4. Remove two small silver screws securing shield to display board. 5. Remove single small silver screw in center below LCD that secures board to chassis. 6. Carefully work board loose from the connectors securing it to the main board. 7. Turn over front board to expose CPU side. Orient so the connectors to main board are down. For new DR-M06T/TH (2/20 watts) Performed on two radios purchased last week. 8. Locate the only 2 round copper solder points approximately 1 to 1/2 inches from upper left corner of CPU. 9. The left solder point when bridged will enable 40 to 60 RX and 40 to 60 or 45 to 60 TX depending on your individual radio. 10. The right solder point when bridged will disable all "cheat" functions from the normal function keys thereby locking radio to factory specifications. Do not bridge both! For regular DR-M06 (1/10 watts) From Internet QRZ mod site. 11. Locate round solder point to left of CPU above left most connector, bridge point to enable 45-60 TX- RX (Depending on radio, results may vary). For Old DR-M06TH models (2/20watt-upgraded M06) From Radio Tech Modifications Book 'B'. 12. Locate 2 round solder points to the left of the CPU and bridge both points for out of band TX-RX (40- 60 TX and 32-87 RX). Not many of these on market. 13. Reassemble radio with care in installing front panel to main board. Connectors are tight and require care during assembly. 14. Once reassembled correctly, Power on radio while holding the 'F" key on front panel. Hold key in until display shows all system information at once (resets the radio). Power off and connect Antenna/Dummy Load and Mic before performing frequency range tests. You would not believe how many radios I see that have this step left out. 73's Charles B. Hedricks KC7FGO
