From: "CARTY ELLIS (KA2Y)" To broadband the DR-110T, while holding the "F" and "VFO/M" keys down, turn off the power and then turn it back on (still holding the keys). The radio now has factory programming reset - you just lost your memories but at least mine now transmits and receives from 130 Mhz to 169 Mhz. Before you do this, remove the top cover - notice the long (2 inchish) loop of yellow wire coming off the back of the front panel - clip it! NOW - after resetting the microprocessor - press the "F" key, then press the "Mhz" key (mine now says 370). press the "f" key again, then press the "Mhz" key again - (mine now says 870!). Mine will scan from 870.000 to 889.995 Mhz. I selected a 15Khz step because the channel spacing in this range is 30 Khz. Toggle the "F" and "Mhz" keys and you're back at 144 mhz. Enjoy. ============================================================================== Alinco DR110 Full Band Modification Step 1. Remove 2 screws located on top of cover. Step 2. Loosen the 4 screws on both sides of top cover (do not remove). Step 3. Remove top cover Step 4. Locate Yellow wire Loop behind tuning Knob (this wire loops from the control board mounted on front pannel). Step 5. Cut loop and tape ends. Step 6. Replace top cover. Step 7. Reset radio (press 'F' and VCO/M keys together. While holding down keys turn off and on Power). Factory settings will be restored however the new frequency range will be from 132 to 173 MHz. Any memory will have to be reprogramed. These insructions are from Alinco, I've done them to my set and it works great. This modification also works on the DR1200T and DR112 radios. Frequency range when applied: 130.000 - 169.995 340.000 - 379.995 870.000 - 889.995 ============================================================================== From: CELLIS%BROCK1P.BITNET@cunyvm.cuny.edu (Carlton Ellis) Don't know about a 570 but on my Alinco DR-110, after making the "cut the yellow wire" mod, the following steps connect the 860 Mhz receiver board and the antenna and the spaker (lets you hear what you can't hear) A. Put radio in VFO mode (not memory) B. Press and release the FP (far left hand) button. C. Press and release the Mhz button. Display now reads in 340 Mhz range. repeat steps B and C. The 860 to 880 mhz rx board is now active. Another cycle of B and C will return your VFO to the 144 Mhz band. The memories have been unaffected - I load the two meter repeaters into the memories and leave the VFO in the 860 Mhz range. Remember at those freqs 860 Mhz rf really gets lost in 50 feet of RG-58 - a small wire stuck in the antenna connector tends to be best. Enjoy but don't let Big Brother know you are listening or that the radio is even capable of said activity.
