Re: [digitalradio] directly modulate computer /thus eliminating transceiver audio input
It'd be pretty cool if that nue-psk device was a little more like this: http://en.wikipedia.org/wiki/TRS-80_Model_100 With the built in keyboard. Is it very cumbersome to have that, a keyboard and your radio going all at once? On Tue, Jul 20, 2010 at 10:20 PM, J. Moen j...@jwmoen.com wrote: Remote control. Very useful in some situations.

Computers offer a richer display with more options and the ability to generate many different modes. The idea is to go directly from the computer via IP to a back box that is broadband and can be remotely located and is mode agnostic. Both approaches have their own advantages. -- *From:* J.

They have a modem that plugs directly into a transceiver' s Data port eliminating the need for PCs and soundcards, but they are now working on a NUE-SDR transceiver that either will fit as a card inside the little modem, or attach underneath it (not sure what their final design will be).

Re: [digitalradio] Re: ROS back bigger and better !
Apparently it's perfectly fine to break the rules because what the big bad government doesn't know won't hurt them. At least according to some people. I wonder if anyone making that flim-flam argument frequents the W6NUT repeater. Wouldn't surprise me in the least. On Mon, Jul 19, 2010 at 9:15 PM, J. Moen j...@jwmoen.com wrote: I agree that traditional SS spread across a very large portion of the band would be bad here in the US if a lot of stations were using it at once. ROS, though we know it's not as good as several other modes, is not that kind of SS. It has limited bandwidth, not much different from a number of other modes, and the ban against it doesn't make sense. So I don't agree with the FCC approach to their regulations, where they ban how the intelligence is transmitted rather than the bandwidth the signal occupies. At the same time, I just can't believe some of my fellow countrymen who think it's ok to pick and choose which rules you'll follow. If you don't like the rules against petty theft, do you just steal? The right way is to campaign to get the rules you don't like changed, and until you do, follow them.

I think there are valid reasons for the FCC only allowing spread spectrum above 222 Mhz (where there is plenty of room!). A single spread spectrum signal on HF may go unnoticed by most stations, but what happens if 100 (in range) are on at the same time? The statistical chances that where will be QRM on your frequency are much higher, the more stations that are on. Our bands have very limited spectrum, and therefore it is up to all of us to cooperate in using the least bandwidth that will do the job. Perhaps it has been forgotten that five years ago, it was the practice for a single wideband Pactor-II mailbox to obliterate the entire PSK31 segment of the 20m band, displacing as many as 30 PSK31 stations. It was only after much discussion that the Pactor mailboxes agreed to move elsewhere. However there remains a Canadian Pactor-III automatic (not listening first) mailbox station just below 14.070 that makes that area unusable by anyone else. The FCC regulations in the US do not allow US Pactor-III mailboxes to operate there, but, without consideration to others, the Canadian Pactor-III station (just across the border) just dominates that frequency at will when it could just as well operate in the automatic subbands with all the other Pactor-III mailboxes. This is a good example of not getting along with your neighbors! The FCC rules may seem unfair, and I am sure SOME are unfair, but there is a process of amendment that insures fair access by all parties, as best can be done. So, if you do not agree with the FCC rules (that PROTECT as well as hinder), take the step of filing a petition to amend the rules and make your case, but do not disregard the current rules because you think they are unfair, because others may not think the same, and they may be harmed by your breaking the rules. We all have to try to get along, and the best way to do that is to observe the local regulations, which have been made for the benefit of the many and not just for the benefit of the select few. If the regulations really deserve to be changed, make your case and let the process of public comment by ALL concerned parties determine what should be done. The FCC makes regulations only for the public benefit, and only after giving everyone a chance to comment. 73, Skip KH6TY

Re: [digitalradio] Re: ROS Developer will continue to auto-spot despite complaints
BTW guys, if you have the technical skill to do so, I'd recommend setting up a virtual machine to test any questionable material out in. Virtualbox is one free VM, qemu is another. Virtualbox is a lot easier to transfer files into. You can set aside a file for a virtual hard drive, install a different OS or another copy of the same one you're running now on it and have everything sandboxed in. I have a few Linux and Windows virtual machines set up on my computer expressly for this purpose. (One Windows XP virtual machine is exclusively for backwards compatibility support. I have a very nice, expensive HP scanner with an automatic document feeder on it that HP has told me they never intend to release Windows 7 drivers for. Virtualbox has support for USB devices. I have the drivers installed in a Windows XP virtual machine. Scanner still works perfectly on XP!) Of course you need licenses. I just happen to have the good fortune to have a few old trash systems I got for cheap with the XP license stickers still attached. I'm not going to go all tin-foil hat over this ROS guys' motives but I will say that I don't think we should trust that he's motivated by goodwill. I'm not accusing, only stating common sense.
