Re: [digitalradio] Re: Noise
I hear it loud and clear in central NC. I heard that ARRL has a person who specializes and spectrum protection and has had good results in the past reporting these problems and following thorugh with the FCC. I do not know who this person is though; it was mentioned in a recent QST article. It sure rips up the PSK31 freqs.. - Original Message - From: mac2251 To: digitalradio@yahoogroups.com Sent: Thursday, July 27, 2006 4:58 PM Subject: [digitalradio] Re: Noise --- In digitalradio@yahoogroups.com, mac2251 [EMAIL PROTECTED] wrote: Anyone know what the signal is on 14071.944 ?

It seems to have one main trail with several weaker trails on either side. I hope its not a permanent fixture on that part of the band,it tears up the psk freqs.

[digitalradio] ALE On-The-Air Week 13-23 October 2006
ALE On-The-Air Week AOTAW 2006 Starts: 0001 UTC Friday 13 OCTOBER (13/10/06) Ends: 1159 UTC Monday 23 OCTOBER (23/10/06) 10 Days of worldwide Amateur Radio ALE activity... More information: http://hflink.com HFLINK is sponsoring a new International Amateur Radio event called: ALE On The Air Week (AOTAW). All ham radio operators worldwide are invited to participate in 10 days of amateur radio HF-ALE Automatic Link Establishment and HF Selcall activity. AOTAW is an open operating event to explore ALE communications and equipment. The experience gained by participation is also useful for HF emergency and disaster relief communications. There are now many hundreds of hams worldwide with ALE stations. The AOTAW gives operators a chance to exercise ALE transceivers, antennas, software, systems, and operating procedures. ALE Operator Certificate for AOTAW2006 === HFLINK issues a unique ALE Operator Certificate to operators who participate in AOTAW. To qualify for an ALE Operator Certificate, the operator must initiate and complete at least 5 QSOs through Automatic Link Establishment with other ALE operators. The ALE link must then be followed by a communication either by voice or texting. Additional certificate endorsement is issued by HFLINK for operators who link and QSO with 25 ALE stations or more. Logs: see HFLINK.COM website for details: http://hflink.com About AOTAW = AOTAW is not a contest. All operators are reminded to be courteous and operate within the recognised Amateur Radio ALE channels and standards. AOTAW provides a way for more operators to gain valuable practical knowledge and expertise in the operation of an Amateur Radio ALE station. Amateur operators who use ALE for government and non-governmental organisations may be especially interested in participation, for this is a chance to explore the various operational aspects of ALE that may not be utilised otherwise. The 10 days of AOTAW enables operators to participate as they can, for any amount of time in the event, and to experience ALE operation under various ionospheric propagation conditions. Also, an ALE demonstration Special Event HF Station will be in operation during the ARRL Pacificon convention in California USA on 14-15 October. ABOUT HFLINK == HFLINK is an international resource: for radio operators using ALE Automatic Link Establishment and Selcall Selective Calling; for the development of communications for organisations, Emergency / Relief networks; and for the development of ALE operating methods applicable to Amateur Radio Service. HFLINK is the Frequency and Address Coordination group for Amateur Radio ALE and Selective Calling. HFLINK Website: http://hflink.com 73---Bonnie KQ6XA . Need a Digital mode QSO?

USB conforms to international standards for ALE / Selcall, and enables compatibility with commercial transceivers. The listed frequency is the USB dial frequency. The 8FSK ALE signal is ~750Hz-2500Hz above dial frequency. Note 2) The ALE-Selcall list is designed for international, regional, and local use in the Amateur Radio Service. All channels are subject to the different rules, regulations, and bandplans of the region and local country of operation. It is the responsibility of every operator to maintain the highest technical and ethical standards for all transmissions. Some channels or modes in the list may not be available in every country. The HF spectrum is a shared resource, so there is no guarantee that a channel is clear in a local area or region. Note 3) Use of 5MHz channels and frequencies may vary in each country. Although 5MHz ALE and SELCALL transmissions are authorised in some countries, USA does not yet allow it on 5MHz. Therefore, operators in USA may receive monitor the 5MHz channels, but care should be taken to lock out the transmitter from making ALE or Selcall transmissions (except in case of an Emergency).

[digitalradio] Recommendations on FAX
A ham about 40 miles away wants to try to make conventional FAX machines work on amateur radio VHF/UHF frequencies. Has anyone tried this and had results that would make it practical? The purpose he envisions, is to be able to send any kind of handwritten notes, such as from medical staff requiring emergency communications. He has considered that it would be operating on full duplex via two bands, e.g., 2 meters/440 and use up to the allowable bandwidth on 2. This would allow for 9k6 bit rates with a 20 KHz signal assuming that a FAX machine has those kinds of tones. I know that other trellis codes may be used and that might not be workable, but I am not sure of the exact tones used by regular telephone FAX machines. I also suggested using Multipsk on HF or VHF and working in simplex, but I have no idea of how well the images would look. A low cost scanner could be used to scan the image and then convert to bmp file format. Even huge files I see will go out in 5 minutes or so. But I have no idea of the quality. Any suggestions on whether this is feasible? 73, Rick, KV9U Need a Digital mode QSO?
