- Here's a mod to be added to your list. I've accomplished the
- wideband RX mods (cutting D8,D9, and D10). Here's how to open up the
- VHF TX:
-
-
- 1. Remove the 12 black screws that hold the top and bottom covers.
- 2. Remove the covers and carefully unplug the speaker from the circuit
- board.
- 3. Remove the 4 screws that hold the head/faceplate to the chassis.
- 4. With the radio right side up, carefully separate the face from the
- chassis about 3/8 of an inch. Be careful of the ribbon cables!
- 5. Tip the face down so that you may view the backside of the head
- unit.
- 6. Locate the three diodes along the bottom center that you cut for
- wideband receive. (D8, D9, D10) Look towards the top and slightly
- to the left of these diodes. You should see two, rectangular
- foil runs that don't have any solder on them. They should be gold
- colored. This is called a "land point".
- 7. BEING VERY CAREFUL OF THE SURFACE-MOUNT DEVICES THAT ARE VERY CLOSE
- TO THE "LAND POINT" AND USING A SOLDERING IRON WITH A SMALL TIP,
- PLACE A SMALL DROP OF SOLDER ACROSS THE LAND POINT. (and I mean a
- small drop. just enough to connect the two foil tabs) Make sure you
- are very careful not to accidently touch a surface-mount device
- with your iron. They lift off very easily and can be a real bear to
- put back into place. The smaller the iron tip, the better!
- 8. Reassemble the radio in the reverse order that you disassembled it.
- Remember to reconnect the speaker!
-
- When you reapply power you should be able to transmit 136-174 MHz. This
- comes in handy if you are a MARS operator.REMEMBER:Transmitting outside
- of the HAM bands is ILLEGAL unless it is an EMERGENCY! i.e.a matter of
- life and death.
-
- Any questions can be directed to N6YUJ @ KA6FUB.#NOCAL.CA.USA.NA
- PER USUAL, ALL MODS ARE COMPLETED AT THE RISK OF THE MODIFIER. N6YUJ
- WILL NOT BE HELD LIABLE FOR ANY DAMAGES OR LOSS DUE TO THE MODIFICATION
- OF THE ABOVE NAMED RADIO. There, now that I have the caveat out of the
- way, I can tell you that I've personally accomplished this mod and it
- works just great. This mod is similar to the IC229H out of band mod.
