Was asked about this in a previous thread , The radio is usually tuned to spec's which would look very close to 5 to 20 give or take a watt either way at 100% Modulation , The cap/resistor mod is then applied. (No need to cut limiter what so ever) There are many different valued caps and resistors used in these mod's that will work , I've used 35 volt 1000uf caps over the years for this along with 1 watt resistors for my radios DK ,usually 68 ohm to 82 ohm will get me 1 to 2 watt DK on my radio 100 ohm should be right around 1/2 a watt if that's what one would desire (usually that would go well on a variable drive if need be) On the Cobra 29 the cap will go at JP36 which is usually a jumper wire on the board right in front to the slight left of the final ,after the radio has been tuned as stated above , you can remove this jumper and insert the cap with the (negative side towards the final), you then turn the radio over and from end to end of the caps leads you can then add your resistor to the caps leads on the bottom side of the board,this will give you your desired DK (then clip the leads), If your radio was swinging 20 after you had tuned it , it will now swing that 20 from the desired DK you were looking for . I use 1 watt resistors because smaller resistors can really get hot and the 1 watters have seemed to handle these mods just fine without major over heating. After the mod is complete ,the radios audio will be off the scale with a stock mic. usually 12 o-clock on the radios mic gain will be all that is needed , I've found that RK-56 mic's work the best along with the 636s or just the stock mic. But the NC mic's surely pick up no back ground at all and can really give the base Station quailty sound when set right on these modded radios. If a variable drive comes to mind with these mods ? You can use the RF gain on the radios (this is just one way) follow the wires from the rf gain to the board ,unsolder from the board (you will then need to add a jumper on the bottom of the board from where the wires of the rf gain were so the rf gain is wide open) then you can take the wires from the rf gain back through the front of the radio pushed through to the bottom side of the radio (you will have plenty of wire to work with from the rf gain) route the wires accross the bottom side of the board stright accross to the end leads of the resistor you used for the radios DK , now you have a varibale drive from your rf gain control. (if you got your wires backwards , just reverse them. (-: of course with any mod's , a decent watt meter and dummy load will surely help the cause. As I said before ,it's not a perfect science but they work all the same and work well as long as one knows where to set his mic gain , because these mod's can give a radio knock you out of your seat nasty loud audio !! They surely help with the drive of any amp , but like I said , you really do not need any kind of power mic with these mods , RK-56 being the best as far as IM concerned. Have fun. (-:
