The above is well said.........When I started out I had it backwards, spent a lot of money on useless mods to radios with clipped limiters, usless microphones with echo turned up too high. I was under the impression that this is what made a BIG radio:blushing:. Wish I would have known then what I know now. I would have spent some of that wasted money on a good antenna, always thought then that the coil antennas outalked a full length whip:blushing:. Would have spent some of that wasted money on an antenna analyzer, but you know I thot if the swr was FLAT that was all that mattered. I wish I had made friends with the people that knew what a good radio should sound like when it was set up right. I got caught up in the "spread the coils for 2 more watts thing":blushing:. It took me a while but I eventually met the right people, and learned some of my lessons the hard way..............always keep your ears open and listen to the "Old Guys".......
They will teach you a lot of things. You can always tell a mudduck by the way he quacks!!!!!
We should really hammer that point home.
DO NOT CLIP THE LIMITER
Noise toys are a waste of money.
If you want more power, buy an amplifier.
The biggest change is from 4w to 100w. 100w to 200w will only yield +3 dB, and 100w to 400w will only yield +6 dB. 6 dB is approximately 1 s-unit.
Heat is the #1 killer of electronics.
You cannot beat a quality microphone.
The only mods really worth doing to any radio:
1.) Alignment. If your radio is TX'ing on 27.1825 as opposed to 27.1850, you're not going to be able to reach peak performance.
2.) Tuning to ensure your radio is outputting 4w deadkey to 12w swing, and your average modulation at normal speaking volume should produce peaks around 90-95%.
3.) Microphone. Quality of input dictates quality of output.
4.) Upgrading your finals is a waste of money when you can purchase an amplifier for $150 or less. This also keeps heat OUT of your radio, and allows them to be dispersed over a large heatsink (amps typically are one big heatsink).
5.) Spending $250 on a "30 kW capable!" coil loaded antenna will only yield you disappointment.
6.) Magnet mounts are one of the worst ways to mount an antenna on the planet.
