Modifications for the ICOM - RogerK

28-03-1999(IC-Q7) Modifying the ICOM IC-Q7A for RX/TXI have discoverd by the process of exploration ,how to modify the IC-Q7A for out of band and the rest of the 440MHZ amateurband transmission. This is a timely task to do. Here is the process.1. Remove battery,antenna,and tuning knob.2. Remove the two screws in the battery housing,and the screws on the SMA jack,and tuning knob.3. Prycover open near bottom of radio with fingers.4. Unsolder speaker leads, and solder joints along the top of radio, including SMA jack, and the one joint connecting the sheildby the coil and speaker connection.5. Remove to screws connecting RF board.6. Gently remove the RF board!7. Remove screw next to function and PTT switch.8. Gently lift the main board out using a angle technique.9. On front of main board there will be a bank of silver color diodes located by the bottom right hand corner of LCD.10. Remove the first diode in the bank.11. Reassemble radio go from step 8 to step 1.After you have assembled radio, insert battery and radio will automatticly turn on, and the display should say "CLEAR".The proccess is now complete.

(Australian version)Hi once again, well I have carried out the mod to expand my IC-Q7E ICOM HANDHELD and it was not as bad as I thought it wasgoing to be.The most important thing about this mod is to do it slowly and carefully, do not use force and if you are unsure stopand study it for a while and then proceed.You must have a good quality Soldering Station such as HAKKO, WELLER, etc with a 0.5mm conical tip, a very small jewelersscrewdriver and some good quality de-soldering braid, If you do not have the above tools then I suggest that you leave thescrews in the radio.Remove the batteries and the two screws under them, remove the antenna and dial knob, remove the slotted retaining nutsbelow the knob and antenna, the back half of the case can now be removed which will expose the top board and next stage.There are three solder points and one screw to be removed on the AUSTRALIAN E MODEL at the top board shielding, two at thetop, one next to the blue channel switch and on the other side next to the antenna connector, the third is above the speaker tothe left with the speaker closest to you, the screw is at the right bottom corner of the big shield, very slowly lift this board until itclears the multi pin white connector in the centre of both boards and with pressure applied to the end of the antenna connectorwith the thumb cautiously remove the top board.The rest is pretty easy, remove the two screws from the bottom main board, one close to the speaker at the bottom of the smalltin shield and the other between the PPT and FUNCTION switch, DO NOT TOUCH THE TWO AT THE TOP OF THE BOARD, desolderthe two speaker wires at the speaker and being very careful of the rubber seals lift the board out and turn over and carryout the mod as per my jpeg pictures.Re-assemble in the opposite manner USING EXTREME CARE my radio will now transmit from, 136 - 174 and 400 - 470.I have not checked to see if there is any drop off in performance specs now, the mod works and seems to work well so I guessthat is the most important thing.
