Exciting Band Opening...

[Don Rasmussen]

The band openings of the last two days at this QTH have allowed a new level of evaluation of K3. I'm mostly on 20m, with a hexbeam, and the last couple days have provided a boost in band activity that I have not seen since I got the transceiver 2 years ago. Of course there are some guys that only got their K2's a couple years ago, they will be equally impressed.

I have still not encountered any scenario where the roofing filter (2.7 and 1.0) improved my operation, the DSP seems as robust as I need it to be for a modest gain antenna.

This solar maximum will be different, the sideband frequencies will have as much fidelity as AM or FM used to. I can still remember having guests in the shack that could not decipher the monkey chatter OT the code. ;-) K3 guys pick up a wider than 2.7 khz roofing filter to take best advantage of this.



Here it comes!

There ain't no monkey chatter on CW, and you can let shack visitors
read the CW from the K3 front panel, unless the operator on the other
end is QLF.

There also ain't no monkey chatter on SSB if the rig RX is on the
correct frequency; even with a 2.1 KHz filter.

Don,

I was having some regrets with my purchase of the 1K filter. But was working my second K3which on has the stock filter and a 400Hz filter during one of the insane contest weekends a couple weeks ago and boy what a difference. It was particularly noticeable on 40M where there were simultaneous CW, RTTY and SSB activities occuring in the same spectrum.

For ragchewing and non-contest times, I agree with you. In congested contest situations, the roofing filters make a heck of a difference. Almost wish I had more slots now! ;o)
