Re: [wsjt-devel] F/H demo at local hamfest
I have had many helpful comments since my post both on forum and direct messages. Thanks to all, I have F/H working "over the air" using no RF at all. My test "Fox" is a desktop computer in the den and my "Hounds" are a couple of laptops on a kitchen counter. Even with all the household noises, washer, scanner, and furnace, the decodes work perfectly. And I'm not pumping out full audio either. Matter of fact, it's amazing how little audio is required, so it's quiet comfortable on the ears. With Fox at 300 and the Hounds at 1500 and 1800, they work great. Then when the Fox clicks on them, they go to 310 and 370, or there about, to finish the contact. We already have at least 5 laptops that will be used in this F/H demo and hopefully we can show the inner workings of the Fox and why things work the way they do. We will also try to make contact in "normal" FT8 mode to show why this doesn't work. Also calling below 1000 will be shown. At least they can see what the Fox sees via a large flat screen TV. Will have users just enter their call in WSJTx and change nothing else as it's of no matter for the demo. That way, they will recognize their own call on the laptop in front of them or the Fox view on the big screen. Again, thanks for the points to the right direction.

Re: [wsjt-devel] F/H demo at local hamfest
I scotch tape the ear buds to the microphone on a pair of Apple ear buds plugged into the PC. Then set up a fox instance and several hound instances on the same PC. Any number of different scenarios can then be demonstrated. 73; W2PKY On Wed, Jan 2, 2019 at 9:57 PM Gene Marsh via wsjt-devel < wsjt-devel@lists.sourceforge.net> wrote: > That’s BRILLIANT! > > 73 de W8NET Miles / “Gene” > Secretary, Portage County Amateur Radio Service (PCARS) > > On Jan 2, 2019, at 9:22 PM, Gary Hinson wrote: > > Hi George, > > > > Another approach is to use AUDIO instead of RF for your demo.

Re: [wsjt-devel] F/H demo at local hamfest
Hi George, Another approach is to use AUDIO instead of RF for your demo. No radios needed, just laptops. Deliberately route the FT8 audio output to the loudspeaker and use the microphone for audio input. In a typical meeting room, there is generally enough audio level for decoding, above the usual hubbub of excited hams. [An interesting point that! FT8 handles weak sigs and QRM very nicely.] I’ve run a workshop like that. The first part of the session involves getting the software installed, running and configured on all the attendees’ laptops, with appropriate audio & station settings and accurate clocks. Ideally that should be a separate pre-session, with competent helpers on hand to deal with the inevitable issues … or maybe a set of ‘loaner’ laptops pre-configured. The second part gets everyone at least receiving and decoding FT8, and hopefully most of them transmitting too, making QSOs within the room. The third part moves into fox-n-hounds, contesting and whatever, for those who have the stamina and interest! 73 GL Gary ZL2iFB From: WB5JJJ Sent: 03 January 2019 12:10 To: WSJT software development Subject: [wsjt-devel] F/H demo at local hamfest I have been asked to set up a F/H demo for our hamfest in March.

Re: [wsjt-devel] F/H demo at local hamfest
Couple of ideas #1 You can actually use speaker/mic to do it so no RF is involved at all. #2 You can run one computer with two big monitors and run 4 or 5 copies of WSJT-X all on virtual audio cables. You can do your own test that way to learn the Fox side a bit better. de Mike W9MDB On Wednesday, January 2, 2019, 5:16:22 PM CST, WB5JJJ wrote: I have been asked to set up a F/H demo for our hamfest in March.
