[RTTY] Pactor QRM To The Other Digital Modes

[Michael Adams]

Well, I just did something I haven't done in a long time.

I opened a Winlink client and updated the Pactor frequency lists.

For whatever it's worth, I see:

VE7RBH, a P4 node, at 14081.5
IQ9IL, a P4 node, at 14082.5

They're legal today (assuming a K-land station wasn't using P4), as the automated subband restriction is an FCC-ism, and there's nothing in Part 97 to prohibit US amateurs from calling the DX nodes.

I might tweak my comments to the FCC.  (I suppose that's why the professionals take their time in submitting comments!)  My mid-term scenario might need revision.  

If US-access to P4 leads to increased utilization of the DX nodes... it's probably not enough to convince the FCC to not drop the symbol rate limit, but it might make for a stronger argument for a bandwidth limit below the ACDS frequencies due to interference.

Yesterday evening I was on 20 meters working a DX station on RTTY. The frequency was 14082.000 kHz and a PACTOR station came on frequency and wiped out the QSO.

Mark N8HOU you can try to gloss over the not listening before transmitting PACTOR QRM issue but this will only happen more not less if RM-11708 becomes a reality.

I've been operating the digital modes since 2003 and RTTY contesting since
2006 and I've had 100's of QSO's destroyed by PACTOR stations that didn't listen before transmitting on top of my QSO. Listening before transmitting is one of the most basic tenets of operating going back to the beginning of hamateur radio.

So I have no doubt that RM-11708 will destroy virtually all digital mode QSO's if allowed to pass. PACTOR operators are some of the most rude and most selfish of all hamateur operators.
