Look at how much we spend a year on housing, utilities, cars, gasoline, food, insurance,cable TV, wife's trips to beauty parlor, etc., etc. Spending a few or several hundred $$ a year on ham radio is a rounding error; a fraction of a percent of what we spend on everything else.

Let's see, I have some ssb equipment that I paid a considerable amount for. However, if I were to tally up the odds and ends, parts and pieces I have for AM I would say , no, AM is not by any means cheaper or less expensive than ssb. One table top transceiver and one legal limit amplifier can cover the entire amateur spectrum, but it would take a room full of real radios to do the same thing and that ain't cheap! The way I see it, this is a great hobby and when we stop treating it as such and become concerned with the cost of things then we are spending too much money on it. I personally spend what I can afford and that's not much. If I had gazillio ns I would spend much more on my hobby and on other things that matter. It's all relative.

Awhile ago there was a thread on this or the Tube Collectors list about the Ampeg SVT and it's use of the 6146. Six of them with the output rating of 300 watts. This amp weighs in at almost 80 lbs and actually bench tests at 300 watts. The 6146B/8298A was the only available tube rated for this at the time. Plate voltage was 660 vdc. When the 6550 came out it was retro fitted and the amp was redesigned to use them. Suprisingly the B+ was raised to 695 vdc. I have the Ampeg service notes for the change over procedure. The 6550's were much safer without the plate cap and actually performed and sounded better anyway. Currently a very desirable amp but costs a small fortune to retube especially with the new production tubes not quite as good as the originals so NOS are really needed. If you could find one of these, the power amplifier is a seperate, complete chassis with enough room to replace the output transformer with a 250 watt or so piece of Mod iron and will set in a 19 inch rack tray. 73, Bill KB3DKS/1 __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body. __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.

Whenever an audio signal is bandpassed or EQ'd in any way there are often serious phase shifts created. So the broader and flatter an audio signal and the further outside of normal hearing range the filtering is kept the easier it is to listen to and more musical due to the proper phase alignment of both higher and lower harmonics of the sound.

Yet, between 3740 and 3775, there was a total absence of any signals that I could hear. I then set the receiver bandwidth to 16 KHz, set the receiver dial to around 3755, and let it sit for about 45 minutes while I puttered around the shack. Only heard 1 weak SSB station come on about 20 minutes later making a direct call to someone and then he disappeared.

They now propose to destroy only ten meters, perhaps figuring that since there has been a long sunspot minimum, no one will be paying attention... http://www.arrl.org/news/stories/2007/03/23/101/?nc=1 Wa3VJB wrote The ARRL, a small, non-profit publishing company in Newington Connecticut, has abandoned a threat to impose a system of bandwidth segregation on the various modes and activities on HF below 10 meters. In an email to the club's volunteer administrators, Dave Sumner, the company's highest-paid, unelected staffer, seems to have acknowledged the overwhelming opposition arrayed against his group's plan the past several years. The threat to AM was specific and unquestionable -- it would have imposed the first-ever, numerical constraints on bandwidth without providing a means for licensees to ensure compliance and ward off unwarranted complaints from those who do not participate in this mode and activity. The scheme would also have characterized AM as a footnote that otherwise would not be in compliance with their misguided system of bandwidth segregation. Sumner wrote, in part, Quote Regulation by bandwidth rather than by mode of emission remains controversial below 28 MHz because of perceived potential impact on established operating patterns, so these proposals were removed from the list with one narrow exception. Those who subscribe to the ARRL can pursue the full text, which contains several insults and additional patronizing language to those of us who dared to question the scheme their group tried to slip through. Keywords: --And for the truly paranoid --don't know all the facts --making their complaints and threats --have other motives It is important to note that the club continues to try to sneak through the small, remaining portion of their scheme that opponents had not, until now, chosen to challenge. Fresh opposition remarks about the fraction the League continues to push are now being filed and accepted on the FCC's Electronic Comment Filing System. The latest challenges join the carefully considered, well-reasoned arguments that gave the ARRL a severe spanking and refuted that group's earlier threat to AM that they now have abandoned.
[AMRadio] advice on el cheapo elecret mics
Hi all, This question should be easy so here goes; When building up a usable high quality mics from one of the small electret elements... What should I do to insure the lowest level hum... I mean other than good shielding... Do they have less AC hum when the batteries are placed closer to the element, in the same shielded housing or can you provide the DC from a remote shielded box and what is a good working load on these things??? thanks in advance 73 vince ka1iic __ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net

Re: [AMRadio] Transmitter fitting
Well to be honest I wasn't the one that came up with the window idea... although I do have an eight foot wide 5 foot tall one in the dining room... The last rig I got up to the second story of this place was a Motorola Sensicon that has two 100TH in the final... a seven foot high and 2 1/2 foot wide deal... Not anywheres as big as the unit you are speaking of I am sure but still a project... I have no idea how heavy it is. I personally would go with the door removal... but that's just me. Have you considered the possibility of using some sort of 'rolls' to make the moving easier? In the past I have used three inch in diameter thick walled piping for these sort of things... Also... will the building that you will be putting this beauty in handle the height? With old houses that wouldn't be a problem but many of the newer ones the height might be problematic... With a single story house modifications to the structure can be much easier than a two story building... I'll think on it a bit... perhaps my crusty old brain will find a cell or two that might still be firing heh Over the years I've been in on so many different moving projects... the worst was a commercial wood furnice (solid cast iron) that we had to raise 9 feet into the air to remove it from the building it was in so we could move the thing to its new home... There were only three of us working on that project... and I was much younger heh Keep me in the loop on this one... 73 vince ka1iic On Saturday 02 December 2006 09:08, Rick Brashear wrote: Vince, Thanks for your suggestion of moving the transmitter into the shack through a window.

Re: [AMRadio] Transmitter fitting
Forgive me if I made things worse but seriously here is what I might try... First off the mod deck and power supply decks will have the most weight... I would pull them out (it is rack mounted I hope...) first and move them as separate units... that will reduce the weight problem quite a bit... As for the rack enclosure... I don't remember how wide you said it was but use some very strong ply wood to form a bridge from ground level or truck level to your house opening... before putting the enclosure on its side have ready some strips of old carpeting lay it down on the plywood with the fuzzy side down and the rubber backing up so it will go against the enclosure... this will help with pushing the thing around... less friction... When you get the enclosure into your house remember that this enclosure must have rear doors as well as front doors so don't plan on pushing it up against a wall... you will need the space of the width of the rear doors plus a little extra so you can get into the back of it to work on it if needed... and if you push it flush against the wall you will need to get into those doors... been there done that... Make absolutely sure your floor stringers can handle the extra weight... if not you will need to build up some extra support before the rig 'settles in' so to speak... I'm sure I have forgot something but if you have questions you may do it on list or direct...

Re: [AMRadio] k1man fined
I don't know of any time limit but there are clear rules regarding station ID's and having control operators on site during a broadcast... What really ended it for me was when K1MAN started sending out those so called 'felony complaint affidavites'... K1MAN has been told by a number of Federal department NOT to do that... He was even warned by Federal Attorneys outside of the Commission to stop it but he insisted on it so... That is a character issue sure but it sure makes ham radio look foolish in the eyes of the world... I will be happy to see this resolved, over and done with. It's been going on for 15 + years and just because of the amount of time involved it doesn't make it right. As Amateurs we are suppose to 'self police' to a degree... In this case anyone that dared question these actions generally end up in court... He would sue people for disagreeing with him... He generally lost but it was a real effective intimidation tool for K1MAN... Rules are rules and it's about time the FCC did show that they have enough interest in Amateur radio to keep it from becoming another CB FUBAR... And that was the way it was going before the recent crackdown... I will never defend a person that acts contrary to any hobby. service etc that I enjoy... and as for emergency communications are concerned... I have seen no evidence that K1MAN has worked in any emergency situation for over 10 years... But then he did say he was 'the most experienced in emergency communications'... Proving the is no end to a pompus windbag... If that offends folks well... what can I say... I sure won't say I'm sorry... at least not sorry for enforcement but I am very sorry it took so long But if anyone doesn't agree... it's a free country... K1MAN didn't allow disagreement tho... go figure... 73 vince On Tuesday 04 April 2006 03:29 pm, Brian Carling wrote: Pete what is the FCC rule regarding Bulletins being limited to ten minutes on amateur radio, please?

Let's get back on track here folks. Actually, there is a connection with the AM community that hits some raw nerves, besides the longtime QRM to the AM window caused by his 3890 kc bulletins. Back in the 1980's during the FCC's AM power proceeding, K1MAN filed a lawsuit in federal court challenging the FCC's decision. There was supposed to have been a 7-year grandfather period under the old power rule, after which the FCC had promised to reconsider, if there is any justification to do so. During a discussion of the issue with ARRL officials, Dave Sumner mentioned that K1MAN's lawsuit had hardened the FCC's position, and he thought it would be very difficult to get them to change their minds at that point. When they went to court, Baxter totally blew the case, according to other AM'ers in attendance. He acted as his own attorney, and during the court proceedings got completely sidetracked onto some tangent about his disaster relief efforts with I.A.R.N. following the Mexico City earthquake (which had absolutely nothing to do with the AM power issue). The judge ruled in favor of the FCC, saying that the court was routinely deferring to the expertise of the regulatory agency (the FCC). Afterwards, I attended an FCC Forum at Dayton, where Johnny Johnston was presiding at the Q-A session. I posed the question, if the FCC was planning to follow up on its stated commitment to reconsider the AM power issue at the end of the grandfather period, in 1990. Johnston's reply: You took us to court, remember? When I pointed out that it was K1MAN who took the FCC to court, Johnston's replay was, As far as I'm concerned, it was the amateur community who took us to court. That's an issue that got caught up in 'circumstances'. The historic AM power limit may have very well fallen victim to a petty ego struggle between Johnston and his hinchmen at the FCC, and K1MAN. I've already had two people leave the list today. If someone left the list over something so trivial as that one thread of discussion, they must be pretty thin-skinned. I doubt if they were contributing very much anyway. We're probably better off without them. Is the delete button broken on their computer?
