Re: [digitalradio] RFSM8000
Normally, when I am operating digital modes, I start out with the full 3.6 kHz bandwidth and only tighten it up when I need to. The non standard mode is likely a much better fit for some rigs. In fact, it would seem that some rigs, even some newer ones, would not be able to operate some of the wide digital modes when you read the passband information. When I look at the specifications of new rigs, I now take that into consideration. ARRL publishes very detailed information on the exact passband for the rigs they test although there is likely some variation with individual equipment. 73, Rick, KV9U John Bradley wrote: heard your second connect as well, as a suggestion make sure that the receive on your rig is as wide as possible , 3khz or better John VE5MU

[digitalradio] Question about SkySweeper
Has anyone tried the SkyOFDM mode or Stanag-4285/4539 modes for Amateur communications in the SkySweeper program? All I have is the demo which doesn't allow live contacts but it can save and load to a wav file which could be replayed I think. According to the SkyOFDM config there are options for speeds from 300bps up to 9600 bps. You can choose either 2KHz or 2.6KHz bandwidth. In the Stanag modes it ranges from 75bps to 2400bps. 73, Sholto KE7HPV. Rick wrote: Ham Radio Deluxe/Digital Master 780 would have the 250/2 as well as many other mode as well as even 125/2.

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.

Re: [digitalradio] Re: Narrow SSTV contact
I am almost always willing to try different modes. It surprises me how few want to do this. However, I admit that many times you try the mode and realize that it is not going to become popular for one reason or another. Any new mode must have some attributes that other modes don't have and even then that does not guarantee adoption by the larger community. But it is partly that we don't have spot frequencies that everybody knows is used for x mode. Sometimes I have been monitoring other conversations and there will be comments about using other modes but they did not find any interest. That is how I made a recent VBDigi/flarq ARQ contact this week:) I don't recall ever using the SSTV part of Multipsk but would be willing to try it. 20 meters would likely be our best band between WI and FL? Perhaps 14.074? 73, Rick, KV9U Jon Maguire wrote: Rick, Patrick sent me this... wanna play? :-) There is a Word document which goal is to show from two Multipsk snapshots how to do the basic operations in SSTV in MFSK16.
