Now that is interesting... Is it the magnetism or the Helium? Be cool to place a iPhone in a helium rich environment and see what happens. I think it was the magnetism, as one cannot breathe Helium well. And after all, Magnetism is a component of RF. Back in the early days of Digital TV Broadcasting, there was an issue discovered in Dallas Texas in 2001. WFAA wanted to do a test of coverage of Digital HD from their facility late at night. So they got a DTV transmitter for Channel 9 and plugged it into their Channel 8 antenna (it was broadband enough to manage good SWR on 9 for the test, and Harris had a combiner all ready to use from another demo). They turned this system on on a Sunday morning at like 4 am to see how coverage in DT matched coverage in NTSC. Every heart monitor system in the Dallas area hospitals went nuts! Seems that heart monitor systems use low level RF to communicate from the patient to the display. These systems used "white area" frequencies in the TV band and, in Dallas, since the nearest channel 9 is in Oklahoma, the suppliers set the frequency for Channel 9... And since these are Part 15 devices, nobody at WFAA TV knew that they were on the Channel 9 frequency, which they chose precisely because there was no other Channel 9 nearby. It isn't known if anybody died, but for Belo Broadcasting and Harris, it was a real fun Sunday morning. Gents, I too am losing interest. Seems that there is a serious lack of brains left in Ham Radio. And it is disheartening. -lu-w4lt- > -----Original Message----- > From: FSG-public [mailto:fsg-public-bounces@lists.keekles.org] On Behalf Of > fsg-public-request(a)lists.keekles.org > Sent: Wednesday, October 31, 2018 8:00 AM > To: fsg-public(a)lists.keekles.org > Subject: FSG-public Digest, Vol 38, Issue 2 > > Send FSG-public mailing list submissions to > fsg-public(a)lists.keekles.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.keekles.org/cgi-bin/mailman/listinfo/fsg-public > or, via email, send a message with subject or body 'help' to > fsg-public-request(a)lists.keekles.org > > You can reach the person managing the list at > fsg-public-owner(a)lists.keekles.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of FSG-public digest..." > > > Today's Topics: > > 1.

HamWAN and Health and Welfare traffic for the Salvation Army

All: Just to let you know that FLG's HamWAN connectivity is being used by Tampa ARC to supply communications services for the Salvation Army's Southeastern Depot facility in relation to the Hurricane Michael recovery efforts in the Panama City area. TARC's HF remote base transceiver, using RemoteHams.com remote base software is currently connected via the internet from a control point in the Salvation Army's Southeastern Depot on Nebraska avenue, through the internet into FLG's HamWAN system connectivity from Downtown Tampa and then to the TARC Clubhouse in East Tampa. This path will be used by the local ARES staff to connect the Salvation Army's logistics staff to their units in the field via the 40 and 80 meter HF bands identifying as W4DUG Remote Base. TARC thanks FSG for their efforts in deploying and maintaining HamWAN's Wireless Internet connectivity facilities. 73 Lu Romero - W4LT TARC
