Title: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: steve_qix on January 06, 2010, 10:12:04 AM Hi !
After aggregating all of the input, comments, emails, etc. the following is proposed. AMFONE is the primary sponsor. I have yet to contact ER mag to see if they are interested. Radio Engineering Associates will provide logistical support (handling logs, issuing certificates, etc.). Anyone who wants to dontate an "award" for a particular category is encouraged to do ! The proposed date is Saturday 6-Feb-2010, 6:00AM Eastern to 2:00AM the next day. PLEASE - if this is a bad date, say something. We have a real shot at making a good splash for AM and having a lot of fun in the process! The event info can be found in 3 forms as follows: http://www.classeradio.com/amtr.pdf (http://www.classeradio.com/amtr.pdf) PDF format (the prettiest) http://www.classeradio.com/amtr.htm (http://www.classeradio.com/amtr.htm) HTML format And, here is a graphic of the PDF: (http://www.classeradio.com/amtr.jpg) Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

Did you want to include some open-ended wording to confirm it's an HF event (yes, I can tell by the gear examples), and perhaps some sort of guide as to where to look for stations ? Thank you - that is a definite oversite. The intent is for this to be an HF event, and I will make the necessary changes. Perhaps we should only use part of the bands, to make it easier to find us (and to allow sections of the bands to be free from those darn corntesters!). Does this make sense? 1880-1950 3710-3900 7150-7295 -or should we just leave it open to the entire band. You know, in thinking about this - maybe for the first one, we should just use 160, 80 and 40 meters...., and I made the changes. Also, put in suggested segments of the bands, and popular AM frequencies 8) Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

Looks good, but I wouldn't suggest limiting the top of 160M. Lots of fellows work AM around 1975-1995. Looks to be a fun event and I hope it stirs-up more thru the course of the year. 73, Jack, W9GT Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: W1AEX on January 06, 2010, 01:46:37 PM It looks great Steve! It should be a lot fun and might encourage many who don't press the AM button on their rigs to give it a try.
I would suggest one change of wording, just for grammar and clarity. The phrase could be used either with or without commas. I believe newer grammar books would go without commas. See the attached graphic. 73, Rob (retired English teacher) Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

There is an odd bug that comes about with some attachments to this forum, where the browser cannot obtain the "file information", and therefore can't download or open the file. Some day, in my copious free time, I will try to debug the problem and determine whether it is a browser thing, or something with the forum software.... In the mean time, can you just type the line in question ;) Thanks and Regards, Steve Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: W1AEX on January 06, 2010, 02:09:11 PM Hi Steve,
Sure. Currently it reads as: Note: Both you, are the station with whom you are QSOing must be using AM. I would propose changing that to something similar to either of these: Note: You and the station you are in QSO with must be using AM. Note: You, and the station you are in QSO with, must be using AM. 73, Rob Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

Thanks for your work on this! It looks like a lot of fun and I hope to have a couple more rigs off the bench and air ready by then.

Anyway, I changed the language (although I didn't use what you suggested because I hadn't seen it).... Also, changed the 160 meter band segments and popular AM frequencies. Check it out! Thanks and Regards, Steve Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: W2VW on January 06, 2010, 02:43:03 PM Quote Note: You, and the station you are in QSO with, must be using AM. Maybe the term AM itself could be specified a little better to avoid all the rocket scientists who will argue ssb is AM. Maybe DSB full carrier AM? Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: W1AEX on January 06, 2010, 02:45:43 PM That looks fine now. The wording of the document is very positive and encouraging to anyone who has tuned into AM activity but hasn't joined in. If it encourages a few more stations out there to give it a shot then we all come out ahead.
Nicely done! Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: k4kyv on January 06, 2010, 02:54:11 PM I would suggest including the list of commonly-used AM frequencies, but eliminate the "suggested band segments". Listing only the former would imply that most of the activity would be expected to take place on the commonly-used AM frequencies, but the use of other frequencies would be permitted if, for example, one were limited by available xtals, antennas, etc. The dual listing of frequency segments is bound to be confusing to someone.
Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: Pete, WA2CWA on January 06, 2010, 03:36:13 PM Maybe I missed it in some earlier discussion, but why isn't 20, 15, or 10 meters included, or any amateur band where phone is allowed? Many AM'ers operate on 20 meters, and if 10 opens up, like it did last weekend, there could be AM activity there. Why limit the bands?
Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: W2INR on January 06, 2010, 04:00:21 PM Steve I like it!!

Steve KL7OF Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: Pete, WA2CWA on January 06, 2010, 05:32:26 PM Steve I like it!! Pete read the thread.

Also, put in suggested segments of the bands, and popular AM frequencies" But no reason! Something wrong with the rest of the bands where phone is allowed. If prospective participants have no room for 160 or 80 meter wire antennas, they may have antennas for other bands. Plus lower power participants may have a better chance of working the higher HF bands and making AM contacts without trying to fight through the high power crud that sometimes prevails on 160, 80, or 40 meters.

Post by: KX5JT on January 06, 2010, 06:49:40 PM I love everything but the DATE. I work every other weekend, 7pm to 7am and naturally Murphy scheduled me for the proposed weekend. But that's my problem and I have to sacrafice quite a bit of activities due to my particular job.
All that being said, otoh, I will be off the 3 weekends in Jan/Feb and March for the hamfests that will be nearby, Jackson, MS - Orange, TX and Rayne, LA so I hope to see some AMers attending those! I'll be wearing my callsign tag! 73 and you guys have fun with this event! Maybe we can do it a couple times a year even! John KX5JT Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: steve_qix on January 06, 2010, 08:00:51 PM Thanks for all of the comments and suggestions. This has come about due to lots of thinking, discussing and hashing by the membership here, and it really works !
Ok, bands - please give some guidance here with respect to the other HF bands outside of 160-40. The only reasons I was thinking of 160-40 was to prevent possible backlash from "other" groups if we step on a bunch of aligators up on 20 meters (where they're not used to lots of AMers). But that may be a misguided thought. I think that's the last item for which we need to reach consensus before we can go "public" ;) You guys who operate 20, 15 and 10 a lot - what do you think about this? Pete, you and probably several others have a lot more experience operating up there. If you (all) think it's not going to cause any fallout....... Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: W2VW on January 06, 2010, 08:10:38 PM It's winter and short notice. The sunspots are minimal. Why not concentrate on the low bands and leave well enough alone this time?
Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: KF1Z on January 06, 2010, 08:30:27 PM Or why not just have it be an all-band thing, and not worry about it?
Not like it's any more work, one way or the other. If people want to work 20, 15, 10 meters... fine.... If for some reason the higher bands open up, great! If not, everyone will be on 160, 75, and 40 anyway. ------ I still think it ought to be a week-end long event ;D Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

As Bruce just mentioned, why limit it to 160, 80 and 40 meters. If folks want to participate on the higher bands, great, if they don't, or the bands are dead, they will either move down to the lower frequencies if they can, or just go watch the tube. I'm not sure what other "groups" you are referring to on bands like 20, 15, or 10 meters. "Man" should know "his" limitations whether operating the AM or SSB modes. This is also a perfect opportunity to generate some AM activity on those bands where, especially on 15 and 10 meters, your "alligators" generally are not a problem as normally can be experienced on 160, 80, and 40 meters. Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: KL7OF on January 06, 2010, 09:35:07 PM I operate 20 AM several times a week in the afternoon on 14286 kc...I would welcome the activity and don't worry about offending any "groups" A" first come" basis is in effect there just like the rest of the phone bands..
Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: K9ACT on January 06, 2010, 11:46:03 PM Ditto on 20 meters. It's a must!

I made changes to the first portion of the document - the commonly used frequency section in particular. I believe the 20 meter frequency is 14285, and the 10 meter freq is 28800.

I have made revisions to the documents, including the addition of a log format sample and pointers to template logs. Please review and comment if I missed or botched something ;D My suggestion is to see how this one goes, and make adjustments (if necessary) for subsequent events. Since we have such a large critical mass with the board membership, this event has great potential for success. We could easily do a 6 meter event at some point (that would be VERY interesting, particularly in summer !), etc. Posting the event information on reflectors, QRZ.com, QTH.com, etc. should really generate some attention (positive, I hope!). Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: WA3VJB on January 07, 2010, 09:39:49 AM OK, if the collective body approves, let's start handing out the flyers.
Volunteers? There are plenty of reflectors and websites where this event will be of interest. Please step up, here, and say where you can post and distribute. Here's what I will do: I will handle distribution of the announcement to the news pages of QRZ.com, eham.net, and to the following email reflectors to which I subscribe: "AMRadio," and "bcast_xmtr_4ham." Do we want to alert the people in Newington, Pete? I nominate you., Who's handling Electric Radio ? Some publishing deadlines for hardcopy outlets may have already passed.

Seriously, someone who lives nearby should go to W1AW and operate AM during the event. We do have the "Vintage AM" station set up there.....although I believe it needs some minor attention (check with Frank) - otherwise, I think it's operational. They have a Flex 5000, and I know that functions correctly. Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

I vote for all Bands! 160 through 10. You never know what band is going to be hot that day and during the time you are on. I think it would be a blast to make some 10 meter AM contacts.

The deadline for January ER was 12/22. I guess the deadline for Feb. is around 1/22 then? In Ray's monthly column (Ray is the ER editor) he mentions operating events. Also, ER has a website. http://www.ermag.com I can try getting in touch with Ray. I think some of us are gg to try 3724 tomorrow night BTW.

So, does everyone in every other time zone convert their operating time to EST so that all the submitted logs are in "time agreement". As Bruce pointed out, contests don't use local time. If everyone submits logs in their local time, I'm glad I'm not the log checker. Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

We should encourage everyone to send along, with their log, a picture of (at least) their transmitters, and, maybe even themselves. I think it would be way cool to see everyone's equipment diplayed all in one spot on da web.... ( and I mean radio equipment ) ;) I know, we can find pics here, and there.... but would be fun to be able to see this stuff all together, wouldn't it?

Post by: K1JJ on January 09, 2010, 12:19:34 PM From a ham's political or rule point of view, PEP can very well be a non-event. But from a technical point of view, AM peak power, pep, studying scope peaks, determining proper phase, etc, (and its derivatives) are very real and mean everything when it comes to properly monitoring and modulating an AM rig.... Depends on your reasons for paying attention to it. ;)

I'm curious - I assume you're using I squared R to figure power with the current meters and openwire line? How do you come up with an accurate "R" to use for the calculation? Or do you also measure voltage across the line with a floating scope probe and use E X I ? T Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

With a 0-10 amp thermocouple rf ammeter in series with the feedline to the antenna or to the calibrated dummy load. Fine Don, You measure in amps, and would convert to watts (if you cared to). I generally measure in volts (into dummy load/with scope) , and convert to watts. Other than you're method may be more accurate or reliable... I don't see what is so wrong or "CB-ish" to want to know what my power output is... Especially if I'm running the higher power rig, and I actually WANT to try and stay within FCC rules, as they are written. :o Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

my station is still pretty JS IMO but it's a lot less JS than it was. Even with setbacks the long term trendline is on the upside for sure. Time for some good 180 proof white lightning homebrew transmitter making. 8) working Cal on 75 AM is more exciting to me than working ZedL on 75 slopbucket which I did when I was toyin around with DX for a year in the mid 80's. more sense of accomplishment.

Rob Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: K1JJ on January 11, 2010, 12:07:21 PM I'm curious - WITHOUT a reference picture of the unmodulated AM carrier, (or carrier lines drawn in) there is no way to know if that modulated waveform picture shows modulation of 100%, 200%. 300% or 400%, etc., positive peaks, correct? Or is there a way by reverse detective work?
BTW, the pic above shows the classic "shark fins" waveform we often talk about associated with a transmitter that will cleanly pass extreme lows effectively. I find this polarity is only possible using a rig that will do this. T Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

100% mod is 4 divisions tall, as it should be, or 2x voltage, 200% is 6 divisions, or 3x the carrier. Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

Yep, that's right, Bill. But what I'm axing is if there was no "2 divisions tall" reference of an unmodulated carrier, are there clues in that 200% modulated waveform that it's more than 100% modulated? IE, does the height of 200% modulation appear different than a 100% modulated waveform in shape, form, etc. I always thought not, but wanted some other opinions. I'm looking for someone to say, "No, you can't estimate the % of modulation when using a negative peak limiter with over 100% positive peaks without an unmodulated reference carrier to look at. There are no telltale signs." (Or are there?) T Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT!

Title: Re: AM Transmitter Rally Final Proposal based on all input - PLEASE COMMENT! Post by: Bill, KD0HG on January 11, 2010, 06:13:14 PM All I can say is an AM signal modulated 200% positive is going to sound awful on an envelope, or diode detector, but OK on a synchronous or product detector.
Once you go past 125% positive peaks, it looks great on a peak-reading wattmeter, but it ain't very good sounding AM. It's DSB with a bit of carrier. Yeah, technology allows you to do 200% positive peaks, but you don't want to if the listeners are using traditional AM detectors. We don't need to sound like SSB contesters, IMO. FWIW, a few AM stations going to 200%-400% positive modulation is one reason why the FCC made the law 1.5KW PEP output, screwing all of us. Sorry, 10 KW PEP of DSB didn't cut it.
