Info below from Mods DK: Enables out-of-band transmit for 1.6 MHz to 54 MHz. This does not enable extended VHF transmit This does not enable AM or FM broadcast band transmit. Your memories will be cleared after this modification, since you need to reset the CPU. Open the top of the radio by removing the 3 top screws and 2 side screws. Look at the radio with the front panel facing you. Gently pull up the speaker and set is aside without damaging the speaker or the wires that attach it to the rig. Note the silver rectangular box near the middle of the PCB marked something like "9 MHz SSB Filter". Move your eyes up from this filter toward the back of the radio. Just before you get to the "D 108" marking, you will see two tiny diodes, two blank spaces, and one additional diode. They look something like this:            D105           --D108-- [ ]            [XX] [XX] [ ] [ ] [XX]            D60 D59 D58 D57 D72 Remove this diode ^^^^  D60 USA low power 50 MHz (remove for 100 W output power)  D59 CPU Tx limit  D58 Eur Fra 144-146 MHz  D57 Den Fra 50 MHz  D72 unknown  D105 unknown Note: French versions have diode D84 (parallel with D59) and D85 on the underside of this print.         D D         8 8         4 5       9 1       +----------+       |IC10 | TD62783AF       +----------+       10 18 D84 CPU Tx limit D85 Fra HF band The second diode from the left needs to be removed. I did this by crushing it with long-nosed pliers. You can also heat it with a low-wattage soldering iron and pull it up with tweezers. Be sure not to damage the other diodes or the PCB. Be sure that you don't apply too much heat, since the heat can damage the PCB and the other diodes. Re-assemble the radio. Reset the CPU by pressing and holding down the UP and DOWN buttons on the front panel and pressing POWER. nondisclosed_email@example.com (yamanx1)Fri, 03 Sep 2010 07:50:25 +0000 ic706 HF/VHFhttps://bfreebandingtalktheplanet.runboard.com/p14838,from=rss#post14838https://bfreebandingtalktheplanet.runboard.com/p14838,from=rss#post14838Hello all,I am trying to wideband my 706,original 1995 model,But I keep getting diff/conflicting info,Diode D59,HAVE DONE THAT,but still no luck,can anybody help?
