From: From Carl The VE32CO Subject: Alinco ALR22T Extended Frequency RX And TX THE ALINCO ALR22T 2 METER RADIO, BEWARE OF ANY STATIC WHEN WORKING WITH THIS RADIOSTEP 01: Remove the top and bottom covers of the radio.STEP 02: Remove the 4 screws that hold the front panel assembly to the main chassis. STEP 03: Pull front panel away from the main chassis very gently. STEP 04: Locate the Volume and Squelch pot on the left side of the radio. STEP 05: Locate the VFO control on the left side of the radio. STEP 06: Between the two above units is an IC that runs vertically between the two units only the 12 pins of the ic are seen from the back. STEP 07: After locating the IC locate 3 sets of unsoldered jumper pads between the IC pins. STEP 08: Make a solder bridge between the top 2 pads, then the middle 2 pads, then between the bottom 2 only of the bottom set of 3 pads. STEP 09: Re Assemble The Radio. STEP 10: Reset The Micro Processor. STEP 11: This mod will extend the RX range as well as the TX range of the above unit. The display will have a range from 29 MHz to 299 MHz but this is just an error of the display as the PLL on a typical radio will RX between 130 MHz and 180 MHz with a TX range that may be a little beyond these these frequencies. GOOD LUCK AND HAPPY MODING 73 From Carl The VE32CO Packet: ve3Zco Internet: ve32co Carl VE3ZCO 44.135.80.8 |
