Subject: MODS FOR FT736R MOD 1 Path: WB1DSW!WA1TPP!W1EDH!W1NRG!N4GAA!N9HSI!KA9YLV!NU9H ... MODIFICATION OF THE PMS ON THE FT736R FOR THE 144 TO 148 MHZ BAND MOD 1 BY G0HEG Modification of the PMS on the FT36R for VHF, Extended coverage on receive from the front panel can be achieved by means of a few simple but repetitive actions, The receive can be extended from about 139 MHz to around 155 MHz By the use of the Repeater shift, This gives a coverage of about 16 MHz, There is no need to snip any of the components, And you will not need a soldering Iron for this Modification, Instructions Make sure that you put the Highest Frequency into VFO B, and the Lowest Frequency into VFO A. 1/ Turn on rig 2/ Put the Rig into Repeater shift for the 144 MHz Band, By pressing the - RPT KEY ( KEY 5 ). 3/ Set the OFFSET to 03.999.9. 4/ Tune the RIG to the Highest Band edge, of 147.999.9 MHz. 5/ Press the REV KEY ( KEY 5 ). 6/ Press the DOWN MHZ Button. You Should now see 148.999.9 MHz on your Digital Readout. 7/ Repeat Steps 5 & 6 Three times more, Alternating between both until you see 151.999.9 MHz on your Digital Readout. 8/ Increase the OFFSET to 07.999.9. 9/ Repeat Steps 5 & 6 Four time more, Alternating between both until you see 155.999.9 MHz on your Digital Readout. 10/ Increase the OFFSET to 11.999.9. 11/ Repeat Steps 5 & 6 Four Times more, Alternating between both until you see 159.999.9 MHz on your Digital Readout. Keep on Increasing the OFFSET by 4, until you get the OFFSET to 99.999.9. And at the same time Keep on Repeating Steps 5 & 6 Four times more after every Increase in the OFFSET until you get the Frequency to 245.999.9 MHz. STAGE 2 Now that you have 245.999.9 MHz in VFO B, And 144.000.0 MHz in VFO A, We come to the next move, Which is this, Press the Function key which is marked with an (F), Followed by the PMS KEY ( KEY 3 ), This stores the New Band edges in the PMS, Now Press the PMS key again, This time Tune to the Highest Frequency in the PMS, Which should now be 245.999.9 MHz. Make sure you have 245.999.9 MHz in VFO B, Make sure that the Frequency in VFO A is Lower than the Frequency in VFO B. Make sure that the Repeater shift is set to - RPT. Make sure that the OFFSET is set to 99.999.9. 1/ Press the REV KEY ( KEY 5 ). 2/ Press the DOWN MHz Button. PAGE 2 3/ Now Repeat Steps 1 & 2 Alternating between both until you get the Frequency to 345.999.9 MHz in the PMS. 4/ Now Press the Following Keys( Key 9,Key 2,Key 4,Key 9 again) in that order. The Magic Number is 9,2,4,9. 5/ Press the F KEY followed by the PMS KEY. This stores the New band edges back in the PMS. 6/ Press the PMS KEY again, Now Tune to the Highest Frequency in the PMS, Which should be 345.999.9 MHz. 7/ Repeat Steps 1 and 2 Alternating Between both until you get the Frequency up to 445.999.9 MHz. 8/ Repeat the Magic Number of 9,2,4,9. 9/ repeat Step 5. 10/ Repeat Step 6. And Tune to the Highest Frequency in the PMS, Which should be 445.999.9 MHz. 11/ Repeat Steps 1 and 2 Alternating Between both until you get the Frequency to 545.999.9 MHz. 12/ Repeat the Magic Number of 9,2,4,9 in that order. 13/ Repeat Step 5. 14/ Repeat Step 6, And Tune to the Highest Frequency in the PMS, Which should be 545.999.9 MHz. 15/ Repeat Steps 1 and 2 Alternating between both until you get the Frequency up to 645.999.9 MHz. 16/ Repeat the Magic Number 9,2,4,9. 17/ Repeat Step 5. 18/ Repeat Step 6, And Tune to the Highest Frequency in the PMS, Which should be 645.999.9 MHz. 19/ Repeat Steps 1 and 2 Alternating Between Both until you get the Frequency up to 745.999.9 MHz. 20/ Repeat the Magic number of 9,2,4,9. 21/ Repeat Step 5. 22/ Repeat Step 6, And Tune to the Highest Frequency in the PMS, Which should be 745.999.9 MHz. 23/ Repeat Steps 1 and 2 Alternating Between both until you get the Frequency up to 845.999.9 MHz. 24/ Repeat the Magic Number of 9,2,4,9 in that order 25/ Repeat Step 5. 26/ Repeat Step 6, And Tune to the Highest Frequency in the PMS, Which should be 845.999.9 MHz. 27/ Repeat Steps 1 and 2 Alternating Between Both until you get the Frequency up to 945.999.9 MHz. 28/ Repeat the Magic Number of 9,2,4,9 in that order. 29/ Repeat Step 5. 30/ Repeat Step 6, And Tune to the Highest Frequency in the PMS, Which should be 945.999.9 MHz. 31/ Repeat Steps 1 and 2 Alternating Between Both until you get the Frequency up to 999.999.9 MHz, Be careful not to go Passed 999.999.9 MHz, Because the Rig automatically Default back to 945.999.9 MHz, And you will have to start again from that point. PAGE 3 32/ Repeat the Magic Number of 9,2,4,9. 33/ Repeat Step 5. 34/ Repeat Step 6, Now slowly Tune Across the Two Band Edges, Until you see 00.000.0 MHz, 35/ Now Whilst still in the PMS Press the VFO A Button. 36/ Repeat the Magic Number of 9,2,4,9. 37/ Repeat Step 5. 38/ Repeat Step 6, Now Press either of the UP or DOWN scan Buttons, and you will find that the RIG will scan between 00.000.0 MHz to 999.999.9 MHz, or 999.999.9 MHz to 00.000.0 MHz. Now that you have set your RIG scanning UP and DOWN, you will find a number of signals on the Band, However you will hear signals up and down the Band that are not there, This can be checked out with a scanner, A signal Generator and a Digital Frequency Meter, But if you do not have these, Do not worry Because you do not need them, Simply put 138.000.0 MHz in to VFO A, And 156,999,9 MHz in to VFO B. 39/ Repeat the Magic Number of 9,2,4,9 in that Order. 40/ Repeat Step 5. 41/ Repeat Step 6. You Have completed this Modification, There are 3 more Mods for this Rig, with the Possiblity of a fourth for the American 220 MHz Band, But as yet I do not have any infomation on this Modification, Mod 2 is for 430/440 MHz, The OFFSET is 09.999.9. The Repeater Shift is + RPT. Press the REV KEY ( KEY 5 ) Followed by the UP MHZ BUTTON. Mod 3 is for 50 MHz, The OFFSET is 01.999.9. The Repeater Shift is + RPT. Press the REV KEY ( KEY 5 ) Followed by the UP MHZ BUTTON. Mod 4 IS for 1296 MHz, The OFFSET is 59.999.9. The Repeater Shift is + RPT. Press the REV KEY ( KEY 5 ) Followed by the UP MHZ BUTTON. Mod 5 is for 220 MHz, The OFFSET is 05.999.9. The Repeater Shift is + RPT. Press the REV KEY ( KEY 5 ) Followed by the UP MHz Button All These Mods are for Receiving only, and can not be used to Transmit out of Band.
