Hi Folks, I just found this groupa few weeks ago and have just been lurking. I have a Buxcomm interface on the way to my QTH, It may be here tomorrow or Tuesday. My question is I am getting some noise/interference from my monitor (Regular CRT, not lcd flatscreen) on my radio. The radio is a Yeasu FT-101Z. IS there any fiz for this interference problem ? Also, do the new LCD flat screen monitors have the same problem ?? Thanks Bob KC9GMN Clinton, Ill
[digitalradio] FW: Ham Radio
Off the digital radio topic , but an interesting reminder from our past. VE7CK is a distant cousin and has been a Ham since the days of sail, hi hi From: Arthur Craig [mailto:[EMAIL PROTECTED] Subject: Re: Ham Radio Ham. Amateur radio operators are often referred to as hams -- a term with an complicated history. At the start of the 1900s, ham was sometimes used to refer to someone as unskilled -- Ham actor being the most common example. Wire-line telegraphy employees at this time had a rich vocabulary of insults for describing less-than-capable operators, and in The Slang of the Wire http://earlyradiohistory.us/1902slng.htm section of Telegraph Talk and Talkers, from the January, 1902 issue of McClure's Magazine, author L. C. Hall noted It is an every-day thing to hear senders characterized as Miss Nancys, rattle-brains, swell-heads, or cranks, or 'jays,' simply because the sound of their dots and dashes suggests the epithets. Hall's review further noted that senders of hog-Morse, called technically 'hams' were known for their propensity for transmitting garbled Morse code. So it was natural, in light of wire-telegraph practice, for commercial stations to dismiss amateur radio operators as hams--and in Floods http://earlyradiohistory.us/1915ama.htm and Wireless by Hanby Carver from the August, 1915 Technical World Magazine the author noted Then someone thought of the 'hams'. This is the name that the commercial wireless service has given to amateur operators... But, interestingly, ham would eventually lose its negative meaning and become a general nickname for all amateurs. This evolution was spotty and not very well documented. As early as the May, 1909 Wireless Registry http://earlyradiohistory.us/1909wr2.htm list in Modern Electrics, Earl C. Hawkins of Minneapolis, Minnesota was listed with the callsign of H.A.M. This callsign was likely assigned by the magazine -- this was before the U.S. government began licencing stations and issuing callsigns -- but was this an inside joke or just a coincidence? In two articles by Robert A. Morton, Wireless Interference http://earlyradiohistory.us/1909ama.htm , in the April, 1909 Electrician and Mechanic, and The Amateur Wireless Operator http://earlyradiohistory.us/1910ama.htm , in the January 15, 1910 The Outlook, the author included an overheard transmission between amateur stations asking Say, do you know the fellow who is putting up a new station out your way? I think he is a ham. However, ham took a while to completely lose its negative connotations. A letter from Western Union employee W. L. Matteson in the December, 1919 issue of QST, Why is an Amateur? http://earlyradiohistory.us/1919why.htm , complained that amateurs, now regulated by the government, were not getting the respect they deserved, noting that Many unknowing land wire telegraphers, hearing the word 'amateur' applied to men connected with wireless, regard him as a 'ham' or 'lid'. But in the next month's issue, Thomas Hunter's exuberant pome, I http://earlyradiohistory.us/1920pome.htm am the Wandering Ham, showed that other amateurs had already embraced ham as a friendly description for their fellow hobbyists. and this from another site : Why an Amateur Radio Operator is called a HAM By Gerry Crenshaw (WD4BIS) (This was previously published in the Amateur Radio Communicator MARCH/APRIL 1994) Have you ever wondered why we radio amateurs are called HAMS? Well, according to the Northern Ohio Radio Society, it goes like this: the word ham was applied in 1908 and was the call letters of one of the first Amateur wireless stations operated by some members of the HARVARD RADIO CLUB. There were Albert S. Hyman, Bob Almy and Peggie Murray. At first, they called their station Hyman-Almy-Murry. Tapping out such a long name in code soon called for a revision and they changed it to HY-AL-MU, using the first two letters of each name. Early in 1909, some confusion resulted between signals from Amateur wireless HYALMU and a Mexican ship named HYALMO, so they decided to use only the first letter of each name and the call became HAM. In the early pioneer unregulated days of radio, Amateur operators picked their own frequency and call letters. Then, as now, some Amateurs had better signals than some commercial stations. The resulting interference finally came to the attention of congressional committees in Washington and they gave much time to proposed legislation designed to critically limit Amateur activity. In 1911, Albert Hyman chose the controversial Wireless Regulation Bill as the topic for his thesis at Harvard. His instructor insisted that a copy be sent to Senator David I. Walsh, a member of one of the committees hearing the bill. The Senator was so impressed, he sent for Hyman to appear before the committee. He was put on the stand and described how the little Amateur station was built. He almost cried when he told

Re: [digitalradio] Monitor interference
Depending on the monitor, you may be able to change the sync frequency in it. This may move the interference but will probably not eliminate it. Changing my sync frequency in my old CRT moved the interference to parts of the bands that I don't use. The monitor manual should tell you what frequencies you can use. If you can use several different ones, increase the frequency one step at a time. You may get flicker at some of the frequencies, so it might take a little experimentation. I recently got an Acer AL2016W LCD flat screen, and have absolutely no interference from it within the ham bands that I use, although I understand such interference is possible from them.

[digitalradio] Introducing Digiital Radio Century Club numbers
It took a while, but I have mined the information associated with the 2900 plus members of the Digitalradio mail list and created membership numbers from those that were obvious amateur radio call signs. Of the 2900+, I managed to find 1415 call signs. Just about 50% You can find the membership list , by call sign and number, at http://www.obriensweb.com/drccalpha.xhtml I will also upload the list sorted alphabetically and by number to the files sections of this mail list To find your call sign , you can use the FIND command in your browser, I will put up a more sophisticated database that you can search when I figure out how (advice/ideas accepted). If you are not listed, it is because I could not find your call sign in the Yahoo groups roster. Just email me and I will add you. New members, henceforth, will automatically be assigned a number when they join. I assigned LOW numbers to some of the well known digital hams and to some of the people that have posted here recently. I have reserved 70 or so other low numbers for people that I may have missed or those with a high number who want to advocate for a lower one. Low numbers will have special multiplier significance in future digital mode contests. So what do you do with the numbers? The numbers will have two purposes: 1. They will be used for future digital mode contests (as part of the exchange) and 2. will be used in casual QSOs where both parties (if members of Digitalradio) will exchange their DRCC Number (Digital Radio Century Club number). I stole the idea from the Straight Key Century Club , a CW club that I belong to . There will be several awards announced in the next few weeks but the first ones will be DRCC .

[digitalradio] Overcrowded on 14109.5
Hi all, I would like to quot John VE5MU (ALE yes ... or no? digitalradio@yahoogroups.com Sun, 23 Sep 2007 11:33:05 -0600) : On the subject of ALE; in my humble opinion some operators have become too focused on ALE, forgetting that ALE is the means to establish which stations available, and the best frequency to communicate from A to B. Once these are established, then other modes can be used to effect the actual communications. I don't want to be a policeman , I think it is to many of them already, but I have a wish. 14109.5 seems to be a bit overcrowded when everyone are sounding and trying to make a AMD qso. What about QSYing to another frequency when a contact is establish on 14109.5? 14112.0 is a great frequency. It is perfect for playing with Patrick's wonderful ARQ FAE mode. Don't flame me now . This is meant to be a constructive proposal. 73 de LA5VNA Steinar
[digitalradio] Multipsk ALE actiivity this week + Complete Bozo's Guide to ALE (?)
Hello to all, Thanks to Bonnie, there are two interesting pictures which show a typical configuration of the 141A mode (ALE). The pictures don't correspond exactly to the last version (4.4.2) but it's 98 % OK. The first step is to leave the soft in monitoring on 14109.5 KHz (on the XCVR) USB and see the ALE frames (up the band closes). There is now some activity and some interest in Europ for this system of modes which is new. 73 Patrick - Original Message - From: expeditionradio To: [EMAIL PROTECTED] Sent: Sunday, October 07, 2007 5:41 AM Subject: [multipsk] Multipsk ALE actiivity this week I would like to encourage all Multipsk users to try ALE 141 this week. There is a lot of activity now, and this is a really good chance to get to know more about how ALE works in Multipsk, and link up with lots of other hams on the air. Here are 2 diagrams that may be helpful for using Multipsk with ALE: http://www.hflink.com/multipsk/MultipskALEoptionsSetup.jpg http://www.hflink.com/multipsk/MPSK_OPTIONS_USA.jpg 73 Bonnie VR2/KQ6XA - ALE On The Air Week: 05-15 October AOTAW (ALE On The Air Week) is an annual International Amateur Radio event sponsored by HFLINK, a resource for ALE, HF Interoperative Communications, and HF Emcomm. Ham radio operators worldwide are invited to participate in a 10 day readiness event of ALE HF activity on the air. AOTAW-2007 is an excellent chance to explore ALE communications. Start: 0001 UTC Friday 05 October End: 2359 UTC Monday 15 October Thousands of amateur radio operators worldwide have ALE capability now, using HF ham transceivers and computers running PCALE software, Multipsk software, or commercial ALE HF transceivers adapted to ham radio ALE use. The experience gained by operator participation is also useful for HF Emergency / Disaster Relief Communications. What Is ALE? Automatic Link Establishment. In the hands of a skilled HF ham operator, ALE is a force multiplier. With the capability to call up a specific HF station, a group of stations, a net, or a networked station, ALE is a versatile digital calling system for initiating and maintaining QSOs with SSB voice, data, text, instant messaging, internet messaging, or image communications. Each ALE station uses the operator's callsign as the digital address in the ALE controller. When not actively in communication with another station, the transceiver constantly scans through a list of frequencies in multiple HF or VHF bands, listening for its callsign. To reach a specific station, the operator simply enters the callsign just like dialing a phone number, and transmits a short digital signal burst. When the distant scanning station detects the first few characters of its callsign, it stops scanning and stays on that frequency. The receiving station, which was muted up until now, typically emits an audible alarm and visual alert for the receiving operator of the incoming call. It also indicates the callsign of the linked station. The two stations' ALE controllers automatically handshake to confirm that a link is established and they are ready to communicate in any mode, such as SSB voice, text or image. All of this happens quite fast, usually within a few minutes. A unique ALE Operator Certificate is available to operators who participate in AOTAW. To qualify for the certificate, the operator simply completes at least 5 QSOs through Automatic Link Establishment communications on HF or VHF. The initial ALE linking QSO can use SSB Voice or AMD Text Message (the standard text messaging format in all ALE systems). See AOTAW Guidelines and Details. http://hflink.com/aotaw Additional certificate endorsements are issued to operators who link with 25 stations or more, or send 2 ALE-SMS text messages through High Frequency Network Pilot Stations. ALE High Frequency Network (HFN) The HFN Pilot Stations are equipped with scanning ALE transceivers, multiband antenna systems, and special software control systems for internet connectivity. Ham radio ALE users in the field on HF connect with the HFN Pilot Stations to exchange digital ALE-SMS text messaging to and from internet devices such as cell mobile phones, black berry type devices, PDAs, PCs and laptops. The free service includes: HF-to-Cellphone message HF-to-email message HF-to-HF message All HFN stations automatically exchange signal reports with each other every hour on every HF band, and all this ALE HF activity with signal reports and messages is displayed in real time on the web at ALE CHANNEL ZERO: http://hflink.net/qso Organized ALE ham activity began about 6 years ago, when a group of operators started working together to experiment with various methods of HF selective calling on HF. The need to call up emergency nets or inter-operability and liaison with government HF systems led many hams to adopt the government ALE standard, called FED-STD-1045 or MIL-STD 188-141. This standard caught on slowly in the ham community, initiated by a few

I will admit that I have looked at, but steered clear of ALE for a number of reasons, which are all personal and maybe based upon my incomplete understanding of what ALE is designed to do. 1st off, ALE seems like a sort of digital net system, where stations sign in and out and there is some system to see what frequency might or might not be better to contact each other on. Again, please bear with my incomplete or partial knowledge, this is all based upon reading other emails on the subject... 2nd, it seems like the sort of mode that standing groups would find very useful. I was a member of RAYNET (the UK Amateur Emergency Network) way back in the 1980s and 90s and they used early Packet radio systems (like Cambridge Packet) before AX.25 became the standard Amateur system. The problem that I could see is that, if too many stations joined in then the channels become overloaded and the advantage of being able to validate contact with certain stations becomes lost. The next issue is defining a 'contact'. Many Amateur awards and certificates are based upon two way peer-to-peer contacts. Nets are, of course, valid as long as the two stations are in direct contact. However, in my own logs I differenciate between direct QSOs and AX.25 contacts, either direct or via digipeaters of some sort, as I cannot always remember what was direct and what was via an intermediary such as a digipeater, IGATE or some other 3rd party system, as it's not always obvious unless you are very careful to log where each contact went and came via at the time. Now, ALE may, or may not suffer from these issue at the moment, but automatic systems which allow one station to be relayed from one frequency to another are not uncommon these days and I could see the advantages, to a network of stations, of having automatic gateways from one band to another. These exist in APRS now. So, ALE is one of those things that I've not become involved in whilst I try to build up more peer-to-peer digital contacts. Dave (G0DJA)

[digitalradio] Consensus on power/audio setting
Long ago, when I started with PSK31, the word was - use low power. Dial the rig down (approximately 20-35) watts,adjust mic gain for ALC flicker, then back mic gain off a smidge. But I've been out of digital mode for a year or more and my recent searches come up with, ...keep the rig at high power (75 - 85 watts) and adjust the mic gain till power meter reads 25-35 watts? It couldn't be till ALC flickers because that's a standard SSB signal at 80 watts at 100% duty cycle and I don't think that was the goal. There was something about keeping the power level high for linearity. Would I use some digital software like the old WinPSK that has a tune button. Push the tune button and adjust mic gain till forward power meter reads the 30 or so watts? What is today's Best Practices. Thank you and 73, Paul

[digitalradio] peer-to-peer ALE
Dave (G0DJA) So, ALE is one of those things that I've not become involved in whilst I try to build up more peer-to-peer digital contacts. Hi Dave, 90% of all ALE contacts are peer-to-peer. You can use any mode once you link up, or you can use the built-in text mode called AMD. There are several other ARQ texting and file transfer modes associated with it. Most operators use ALE to initiate or maintain communications with another specific station, or a group, or a net. It also can be used to send/receive e-messages via internet or SMS phone system, if you connect with one of the 9 HFN Pilot Stations. The HFN Pilot Stations also can relay a text message HF-to-HF between two stations, but this feature is not normally used very much. Perhaps during an emergency it will be. 73 Bonnie VR2/KQ6XA
[digitalradio] Re: Consensus on power/audio setting
You are dealing with two issues here, continuous power output and distortion caused by ALC. PSK31 is basically like turning your transmitter on continuously. If your rig is rated for continuous full output then you should have no problem. Please recognize that most amateur rigs are rated for intermittent service not for continuous service. Also, maximum output may not result in the cleanest signal. The best level can vary from rig to rig and should be measured, however, in most cases, running less power results in cleaner signals. The other issue is caused by ALC. Remember, ALC is used to limit the drive levels of amplifiers in the transmitter chain to prevent overdriving and the consequent intermodulation distortion (IMD) that results. With SSB you can use ALC to achieve some compression without raising distortion to objectionable levels. But, even with SSB, if you really bang the ALC hard you will get increased splatter, or IMD. With PSK31, if you see any ALC, you can be sure you are overdriving amplifier stages in the transmitter chain including the final amplifier. This causes IMD and a very wide signal.
