Re: [digitalradio] NBEMS/Flarq Frequencies
Being so close to another net frequency is not going to work unless you provide a proper filter. Using flarq efficiently you need to * use a 500 Hz filter or better * use a distance of 500 Hz. We have tried to put 2 pskmail servers on a 250 Hz distance but they qrm'ed each other in such a way that is was not feasible. We had to increase the distance to 500 Hz. To use a broad filter and let the DSP do the filtering is basically wrong. The AGC will wipe out the flarq signal to the effect that all packets are damaged and no transfer is possible. To take advantage of the small bandwidth of PSK63 you need to have a matched (100 Hz) filter. If you don't have that it makes more sense to increase the speed to PSK250. That has the added advantage of being less frequency-critical. Just some of the experience we gathered with pskmail... 73, Rein PA0R Pronet came on and I was unable to print anything for it, my beacon will be 10.137/1500hz, I have one single short file in the folder for tranfer.

Re: [digitalradio] NBEMS/Flarq Frequencies
This rather surprises me as I can normally decode PSK31 stations right next to each other with no problems at all. Even if they are almost touching each other on the waterfall. And that is using a very wide filter, typically voice bandwidth, unless I have some very strong signals that is desensing the rig too much. Did you mean that the center frequencies of the PSK250 mode were separated by 500 Hz? If so, that would be as close as you could possibly get at that baud rate and bandwidth since each modulation would be out about 250 Hz from the center frequency. Anything closer than 500 Hz from the center frequencies would overlap with a 250 baud rate. 73, Rick, KV9U Rein Couperus wrote: Being so close to another net frequency is not going to work unless you provide a proper filter.

[digitalradio] NBEMS/Flarq Frequencies
Where and when is the testing of NBEMS and Flarq going on? I would like to do some testing from here. 73 Ted W4ZE Port St Lucie, FL
Re: [digitalradio] NBEMS/Flarq Frequencies
Propnet on 30m was very strong here. Around 1100 Hz when my transceiver was set to 10.137, I think. Correct me if I am wrong, but nothing wrong with working along side Propnet, just not on top of it. No problem - just wait for a few minutes and if and when Propnet comes on, move over a few hundred Hz. LIke Flip Wilson's Geraldine used to say, What you see is what you get, Honey (on the waterfall). Although we have debated how to specify a PSK31 frequency for years (as RF frequency), it is more understandable to just say, for example, 10.137 USB and 1500 Hz tone frequency. I'll be watching 30m now and will be available for some NBEMS ARQ file transfers. 73, Skip KH6TY - Original Message - From: Andrew O'Brien [EMAIL PROTECTED] To: digitalradio@yahoogroups.com Sent: Friday, January 04, 2008 6:12 PM Subject: Re: [digitalradio] NBEMS/Flarq Frequencies I think it might make sense to use the SAME frequencies as Propnet.

Re: [digitalradio] NBEMS/Flarq Frequencies
Aren't the PropNet operators monitoring their transmissions? Here in the U.S. beacons are not permitted below the 10 meter band except for the special international beacons. I realize that there are scofflaws (or worse) operating outside the rules, but it does not seem wise to promote this unless it is determined legal by the FCC ( I have not heard back yet from the FCC for help in understanding numerous issues and operations that are going on our bands). If anyone transmits a test signal (which PropNet is likely considered), and then someone else comes along and uses that frequency, such as a digital mode Q, then that frequency is busy and it is illegal for anyone to intentionally transmit on that frequency if they can hear either of the stations. Today I was able to correctly configure my emachines computer to run the vbdigi software using the suggested frequency of 10137 +1000 Hz. I happened to be on the same time as Skip, KH6TY, and so we were able to work each other although signals were fairly weak with his 3 watts to an inside antenna. (Hey, not bad, right?) The solution for the computer problem, was to insure that both the input and outputs in the Windows Control Panel Sound applet were going to the same sound card. But in order to use my Sound Blaster Live! card, I was forced to make it the default card under Windows. This created some other problems with not being able to use the front earphone jack that connects to the Realtek built-in card, for listening to MP3's, etc., but it seemed the only practical solution for now. At least I can key up the old rig with VOX, via rear panel connectors, which is something I can not do with my ICOM 756 Pro 2. 73, Rick, KV9U Andrew O'Brien wrote: I think it might make sense to use the SAME frequencies as Propnet.

Re: [digitalradio] NBEMS/Flarq Frequencies
Aren't all automatic transmission outside the auto subbands supposed to be under the control of an operator present? If there is activity on the frequency, then the assumption is that the control operator is not present or he would not have allowed transmission. Mark, where are you!
