[600MRG] 630 Meter Band Use

[Dave Riley]

Having a 7 khz. wide band for all modes inclusive seems very narrow but 
I find little to no QRM between stations...

When the JT9 waterfall is on there appears a lot of 'unused real estate' 
available and that is only 2.2 khz. wide...

Aside from a few 'bumps' we seem to be a band of gentlemen with plenty 
of elbow room to grow...

After years of transmitter tweeking and improving low pass filtering we 
seem to be overall very clean as well...

Trying to wiggle a 5 hz. wide signal around in order to avoid another 
station doesn't seem an every day need...

The 3:1 antenna SWR points here are 10 khz. wide FWIW and 47 watts tpo...

A 400' litz loop works best here with plenty of room for experiments...

My 2 cents, TNX from DaveR @ aa1a
