    I would not imagine the radio would need that if you are not running to within an inch of it's life! Interesting though all the same!

    If he used those silpads I've been reading about here, he wouldn't have heat transfer compound smeared all over the coils.

    Is that heat sink compound, or is that where he hit the coil with the drill bit? LOL I wish it had side band too.

    I wondered that too. It would only have taken a second to remove the coil then reinstall it when done. Drilling the hole would not be that tough but how the heck can you get a tap and t-handle in that space. He could also have removed the heat sink as well then re-install.

    I figure he drilled and tapped it from the outside between the fins.

    That is a good idea if you do not care how it looks. I prefer to punch holes when I can so I do not have metal shaving to deal with. That is not possible in this situation!

    I have to say that few "professionals" do a job right today. They usually take shortcuts often doing things that a DIY'er would do because it is easier and quicker. Not meaning to offend the real highly skilled electronic repair technicians on this site but usually when you see Electronic Technician and CB in the same sentence it is more of an oxymoron than it is a description of skill or competence!

    What Lester did is what a DIY'er would do. If he was a professional he would have just sad no to the customer and moved on to the next job. I am wondering if that mod parts and bench time are 1/3 to 1/2 the purchase price of the radio! LOL I can not imagine that radio benefited that much from that. It would be like adding NOS to an air cooled VW van. You can do it but at the end of the day it is a blockhead thing to do!

    Likewise did that radio benefit at all from having it's power filter cap and what ever cap he increased in size? Prob. not but since you empirical testing was done before or after we will never know. Doing work that either does not need to be done or is of little to no benefit tot he customer just because you can is a slippery slope!

    If I recall properly as well he does not even use decent cap's I think I remember him using Jamicon JWON or some other cheap Chinese cap! Not in anything I own!

    That Max Mod thing is snake oil.

    To quote someone... “don’t believe the hype”

    I guess if it where me i would mill out of pice of copper plate and make an adaptor to clear every thing if it it was posable...
    But i have not seen this MAX-MOD make any more power then the TIP36c that was in there.
    in the end your week link is your finals..

    Wouldn't those long wires pick up RF being in close proximity to the output filter tank coils?

    Probably, need to twist-em!

    Personally, I would not mod this radio other than adding some filters to the input power, as it picks up a lot of ignition noise, and I have mine directly wired to the battery.,

    Such a waste of money... but it is the customer's radio to do with as he pleases.

    So much bad thinking going into this whole mess that it makes my head hurt....
