So my next playtoy is a 674B Hy-gain 5 that i put Upper's and Lower channel's in. Make sure all the channel's work and there no dead Xtal's
I pulled all the A Xtal's out, 23.330, 23.380, 23.430, 23.480, 23.530, and 23.580.
Took a 3 pole double throw switch and solderd 3 different color wires to the center terminal's, The color's i used are red, white and yellow. These need to be long enough to solder back on the board where you removed the oem xtal's and it all depend's where you want to mount your 2 added xtal switches.
Then on one side terminal i solderd the 23.330 and the red wire, the 2nd terminal i solderd the 23.380 and the white wire and the last one i solderd the 23.430 xtal to it and the yellow wire
On the other side of the 3 pole switch i solderd on one side of a Xtal socket on the 3 remaining pin's. (This is so i just plug in the new Xtal's instead of soldering)
Now take a black wire and strip the insulation off it and solder it to the remaining sides of the oem xtal and the other sides of the xtal socket. This black wire will be your ground wire for all your Xtal's, Now solder a longer black wire to the ground wire to the xtal's.
Now what i put in for the extra channel xtals was a 23.230 to match up beside the 23.330, 23.280 to match up beside the 23.380 and 23.630 to match up beside the 23.430.
Now what this gives me is 3 set's of extra's for one switch. so with the switch in the down position i get the normal 23. With the switch up i get these freq's.
Channel 1 is now 26.865, 2 is 26.875, 3 is 26.885, 4 is 26.905, 5 is 26.915, 6 is 26.925, 7 is 26.935, 8 is 26.955 These are the lower's.
Channel 9 is now 27.265, 10 is now 27.275, 11 is now 27.285 and 12 is 27.305. These are the upper's.
Now back to the mod. Mount the switch as close as ya can to where the oem xtal's were removed and run the 4 wires over and to the bottom of the board where the xtal's were removed. Shorten the 4 wires as short as possible befor soldering to the board. Looking at the bottom of the board you will see the traces that link the channel selector to the xtal. In the picture i post you will see white dot's on the traces, to the left of these traces and where the oem xtals were removed is where you want to solder your 3 different color wires too and just to the left of where you solder these 3 wires too is the other side where your oem xtal solderd to. This is the ground side where you connected all the unswitched ground wires to and this is where you'll solder the black ground wire too.
Now looking at this picture, the bottom of the picture is the mic socket and the top is toward the middle of the radio. now this is the order that the xtal's were solderd on the board, going from top of the picture toward the mic socket.
X208/ oem xtal is 23.480, Added xtal is 23.680 and it's the blue wire.
X207/ oem xtal is 23.430, Added xtal is 23.630 and it's the yellow wire.
X206/ oem xtal is 23.380, Added xtal is 23.280 and it's the white wire.
X205/ oem xtal is 23.330, Added xtal is 23.230 and it's the red wire.
X210/ oem xtal is 23.580, Added xtal is 23.780 and it's the tan wire.
X209/ oem xtal is 23.530, Added xtas is 23.730 and it's the green wire.
You can use what ever color wire you want, i used 22 gauge stranded. you could use solid wire like from a chunk of cat 5 cable if ya want too. Just keep track of what color wire you solder to the middle of the 3 pole double throw switch and the xtal's that are assocated with that wire.
Note that i mentioned i used red, white, yellow and black making the above switch and i have 6 wire color's listed going to the board where the oem xtal's were removed from. well the blue, tan and green wires are on the 2nd switch you will make.
Now take another 3 pole double pole switch and solder the blue wire to the center terminal and the green and the tan wires. Solder the oem 23.480 xtal to the other side of the blue wire, the oem 23.530 xtal to the green wire and the oem 23.580 xtal. Now do as before, solder on xtal socket's on to the other side of the switch.
Plug in the added 23.680 xtal inline with the oem xtal 23.480 and the blue wire. Plug in the added 23.730 xtal inline with the oem 23.530 xtal and the green wire. Plug in the added 23.780 xtal inline with the oem 23.580 xtal and the tan wire. Strip a wire and solder it to the other side of the oem xtals and the added xtal holder's as before and solder on a longer black wire to run to a ground. Find a spot to mount the 2nd switch close to the previous removed xtals as mention'd before.
Just a little fyi on these 3 pole double throw switches. They are on-on switches and serve as 3 toggle switches in one. You have 3 set's of xtal's you will change with each switch. They are eather switched to the regular 23 channel's in the down position or switched up to get the lower's and upper's. I stole these extra xtal's out of a frankenstine channel mod that had 6 toggle switches on the bottom and every time you wanted to get the extra channel's you had to flip one switch and run through channel's 1 through 4, then to get the other set of extra channel's you had to flip the previous switch back, flip the other switch and go back through channel's 1 through 4 again. now do this 6 times fast. lol. With my way you can do the hole opperation with 2 added toggle switches and run through all 23 channel's (24 channel's if you add 22A. lol) You'll get 8 lower channels and 4 upper's on one switch and 11 upper's with the other switch, (12 upper's if you add 22A)
Now back to the mod. test out your work and make sure you have all the origional 23 channel's with both switches in the flipped down position.
Now flip the switch up and here's what you will have.
Channel 1=26.865, 2=26.875, 3=26.885, 4=26.905. 5=26.915, 6=26.925, 7=26.935, 8=26.955, 9=27.265, 10=27.275, 11=27.285, 12=27.305, 13=27.315, 14=27.325, 15=27.335, 16=27.355, 17=27.365, 18=27.375, 19=27.385, 20=27.405, 21=27.415, 22=27.425, (22A if you have it =27.435), 23=27.455
Once you have confermed all channel are working, remove the two switches and hot glue all the xtal's together on each switch and reinstall the switches where you choose. Note that when done the switches will be flipped down for regular 23 channel's and up for the extra's.
Also note that in between every 3rd and 4th channel you still have the 10 kHZ jump and if you don't have 22A installed you'll have a 20kHZ jusm between 22 and 23 channel's.
Good luck if any one decides to do this mod. probibly not many want to, but just in case. This is the way i did it, you can choose what ever you want, if you don't want the lower's you can substute a 4 pole double throw switch and do all the upper's i did here on one switch or do as i did with 2, 3 pole double pole switches and find a 23.830 and a 23.880 xtal and reorganize what i did by removing the 23.230 and 23.280 xtal's. moving all the other xtal's up two spot's and adding the 23.830 and the 23.880 xtals in the same order. and do all upper's, The sky is the limit and what xtal's you have laying around.
I'll up load some pictures as soon.
I pulled all the A Xtal's out, 23.330, 23.380, 23.430, 23.480, 23.530, and 23.580.
Took a 3 pole double throw switch and solderd 3 different color wires to the center terminal's, The color's i used are red, white and yellow. These need to be long enough to solder back on the board where you removed the oem xtal's and it all depend's where you want to mount your 2 added xtal switches.
Then on one side terminal i solderd the 23.330 and the red wire, the 2nd terminal i solderd the 23.380 and the white wire and the last one i solderd the 23.430 xtal to it and the yellow wire
On the other side of the 3 pole switch i solderd on one side of a Xtal socket on the 3 remaining pin's. (This is so i just plug in the new Xtal's instead of soldering)
Now take a black wire and strip the insulation off it and solder it to the remaining sides of the oem xtal and the other sides of the xtal socket. This black wire will be your ground wire for all your Xtal's, Now solder a longer black wire to the ground wire to the xtal's.
Now what i put in for the extra channel xtals was a 23.230 to match up beside the 23.330, 23.280 to match up beside the 23.380 and 23.630 to match up beside the 23.430.
Now what this gives me is 3 set's of extra's for one switch. so with the switch in the down position i get the normal 23. With the switch up i get these freq's.
Channel 1 is now 26.865, 2 is 26.875, 3 is 26.885, 4 is 26.905, 5 is 26.915, 6 is 26.925, 7 is 26.935, 8 is 26.955 These are the lower's.
Channel 9 is now 27.265, 10 is now 27.275, 11 is now 27.285 and 12 is 27.305. These are the upper's.
Now back to the mod. Mount the switch as close as ya can to where the oem xtal's were removed and run the 4 wires over and to the bottom of the board where the xtal's were removed. Shorten the 4 wires as short as possible befor soldering to the board. Looking at the bottom of the board you will see the traces that link the channel selector to the xtal. In the picture i post you will see white dot's on the traces, to the left of these traces and where the oem xtals were removed is where you want to solder your 3 different color wires too and just to the left of where you solder these 3 wires too is the other side where your oem xtal solderd to. This is the ground side where you connected all the unswitched ground wires to and this is where you'll solder the black ground wire too.
Now looking at this picture, the bottom of the picture is the mic socket and the top is toward the middle of the radio. now this is the order that the xtal's were solderd on the board, going from top of the picture toward the mic socket.
X208/ oem xtal is 23.480, Added xtal is 23.680 and it's the blue wire.
X207/ oem xtal is 23.430, Added xtal is 23.630 and it's the yellow wire.
X206/ oem xtal is 23.380, Added xtal is 23.280 and it's the white wire.
X205/ oem xtal is 23.330, Added xtal is 23.230 and it's the red wire.
X210/ oem xtal is 23.580, Added xtal is 23.780 and it's the tan wire.
X209/ oem xtal is 23.530, Added xtas is 23.730 and it's the green wire.

Now take another 3 pole double pole switch and solder the blue wire to the center terminal and the green and the tan wires. Solder the oem 23.480 xtal to the other side of the blue wire, the oem 23.530 xtal to the green wire and the oem 23.580 xtal. Now do as before, solder on xtal socket's on to the other side of the switch.
Plug in the added 23.680 xtal inline with the oem xtal 23.480 and the blue wire. Plug in the added 23.730 xtal inline with the oem 23.530 xtal and the green wire. Plug in the added 23.780 xtal inline with the oem 23.580 xtal and the tan wire. Strip a wire and solder it to the other side of the oem xtals and the added xtal holder's as before and solder on a longer black wire to run to a ground. Find a spot to mount the 2nd switch close to the previous removed xtals as mention'd before.
