On 8 Feb, midday US PST, I heard a recorded voice just saying what sounded like Five over and over again. My radio was tuned to 14070. I also witnessed some digital modes I'm not familiar with that were much wider than PSK31 - as wide as MT63 at least but I don't think that's what they were. They just swamped maybe 10 different PSK31 QSOs, at least at my QTH in San Diego. I don't know if the modes to be used at 14070 are a gentlepersons' agreement or are FCC/ITU proscribed (I assume the former) but I know that wide modes are usually used closer to 14100 so these were either rude or clueless people.

Re: [digitalradio] Re: SSB on 14070
That's an interesting frequency to select for the source of voice qrm. I wouldn't be so fast to blame VE's or other non-US stations for this increased interference. That is the BFO (14070 dial) frequency for virtually every transceiver running PSK on 20 meters. With the proliferation of PSK31 using soundcard technology, my first inclination would be some operators do not mute or disable their microphone when using AFSK for these modes. So now there's a live mic in the shack while they are happily PSKing away. Everything is fine until they shout... HEY MARTHA, WHAT'S FOR DINNER TODAY? Instant qrm. 50 years ago the operator knew when his microphone was live and on the air! :-) 73 de Bob - KØRC in MN - Original Message - From: Rick To: digitalradio@yahoogroups.com Sent: Thursday, February 07, 2008 8:21 AM Subject: Re: [digitalradio] Re: SSB on 14070 I have been hearing more activity that appears to be illegal voice than I have ever heard in the past 50 years. It is so bad that a number of times I have been hearing voice transmissions that interfere with WWV reception! Probably much of the voice activity on the ham bands that are in the U.S. text data portions of the bands are due to operators in other countries moving lower. I know that Canadians in particular were very upset with the liberalization of the U.S. voice frequencies some years ago and declared that they would move down below the U.S. frequencies. In fact, I remember someone commenting that if the U.S. ever increased liberalization of the voice bands, they would just move down even further. Since the more recent increase in voice bandwidths for U.S. hams this may have caused at least some of this. Although on 40 meters you will often hear wide split operation because those outside of Region 2 may not have as wide a band, I recently heard a CU2 working narrow split down around the digital area. When the 10 meter band is open we can have many pirates operating in the text data areas of the band since that likely seems like an unused part of the spectrum to those stations. 73, Rick, KV9U Brad wrote: --- In digitalradio@yahoogroups.com, Leigh L Klotz, Jr. [EMAIL PROTECTED] wrote: I have ben hearing what sounds like Vietnamese on 14.070 LSB.
