[AMRadio] Crystals Rock ! ( sorry for the pun )
Interesting Mark... I have a number of quartz crystal blanks available for the large FT171B crystals used in the BC610. Some I have marked - some random. They are almost all in the 3500 - 4000 kHz range if anyone wants to try some pencilling, penning or grinding with these. Drop me an e-mail of fthe list and I can supply information. 73 - Bry, AF4K From: Mark Foltarz folt...@rocketmail.com Did my first crystal grind for the BC 610 last night. Got darn close. Started with a 3570 and ground up to 3655.3 . Overshot by 300 hz. Might try to pencil it down. de KA4JVY Mark -~ø¤º°º¤ø~-ßrÿ in FLÕRÎÐÁ-~ø¤º°º¤ø~- __ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

Re: [AMRadio] AM IARU Region 2 Bandplan
We should try to get them to include language stating that AM may be used ANYWHERE that other amplitude modulated telephony modes such as SB are allowed, AND they should state that there are areas in which regular AM operation is noted, such as from 3870 to 3890 kHz. (Also now 3650 to 3750 kHz is being used more and more too) We do NOT want AM to become ghetto-ized. This could eventually lead to specific limitations. 73 - Bry, AF4K From: screwdriver he...@swbell.net The inadvertent omission of the AM center of activity frequency (calling frequency) -- 3.885 MHz on 80 meters -- has already been noted, and this will be one of the recommended revisions. -~ø¤º°º¤ø~-ßrÿ in FLÕRÎÐÁ-~ø¤º°º¤ø~- __ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Post: AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.

Re: [AMRadio] AM IARU Region 2 Bandplan
As always, everyone has an opinion. Mine is that this is not a calling frequency, as it is certainly not utilized that way. it is a common area for AM to hang out I feel that it should not even be mentioned as the is no SSB or CW calling frequency, this only gives rogue ssb ops a chance to squawk that we are off freq. That said I almost never operate in that region as there is simply too much QRM, much better at the low end of the band, I find a lot of contacts from 3685 to 3725.

One of the topics on the agenda will be the Region 2 HF band plan. This band plan is harmonized with -- spectrum management-speak for very similar to -- the IARU Region 1 and Region 3 band plans. According to ARRL President Kay Craigie, N3KN, many hams in the USA probably did not know there was such as thing as a Region 2 band plan until recently. Now, however, many more American hams have heard of it, but may not know how -- if at all -- this band plan affects them. Here are important facts for American hams to keep in mind: IARU band plans are voluntary guidelines. They do not have the force of FCC regulations. It would be inappropriate to incorporate Region 2 band plans into the FCC rules, and the ARRL has no plan to petition the FCC to do so. Most other countries do not have the detailed sub-band regulations that are in Part 97 of the FCC Rules; for amateurs in those countries, IARU band plans offer the only guidance on frequency use. The recognition of a calling frequency or band segment for a particular purpose or mode in the IARU band plan does not convey any special rights or exclusivity of use. A new, more transparent procedure will be followed this year for considering possible changes to the Region 2 band plan. The ARRL is cooperating with this procedure by inviting input to be sent to the ARRL Board of Directors' Band Planning Committee. The committee will review the existing Region 2 band plan, consider input from the amateur community and make recommendations to the ARRL Board for submission to IARU Region 2. The inadvertent omission of the AM center of activity frequency (calling frequency) -- 3.885 MHz on 80 meters -- has already been noted, and this will be one of the recommended revisions. The deadline line set by Region 2 for gathering input and formulating recommendations is rather short. Amateurs who would like to submit input should take the following steps: First, study the existing IARU Region 2 band plan posted on the Region 2 Web site. The Region 1 and Region 3 band plans are also posted there, so be sure you are looking at the band plan for Region 2. Next, formulate a clear statement of any change you propose. Include a brief explanation of why you think the change would be beneficial. Please include your name and call sign in your input. Finally, send your input via e-mail no later than April 5, 2010.

Actually AM is true (radiotele)phone; SSB is wildly changing CW in frequency and amplitude beating against an oscillator in the receiver. : ) rob k5uj On Fri, Mar 5, 2010 at 7:58 AM, Todd, KA1KAQ ka1...@gmail.com wrote: On Fri, Mar 5, 2010 at 7:03 AM, Bry Carling bcarl...@cfl.rr.com wrote: We should try to get them to include language stating that AM may be used ANYWHERE that other amplitude modulated telephony modes such as SB are allowed, This is easily covered by using the term 'phone' rather than separating AM and trying to make it some 'specialty' that somehow deserves special treatment or special frequencies.

[AMRadio] Input to IARU Region 2 Bandplan
In reading over the IARU Region 2 MF/HF Band Plan, Effective January 1, 2008, I notice that the only frequencies between 1800 kHz and 297000 kHz where DSB AM Phone is allowed are from 3600 to 3625 kHz, 3875 to 3900 kHz, 7100 to 7300 kHz, 14285 to 14300 kHz, and 29000 to 29300 kHz. My position is that DSB AM should be recognized as a Preferred mode on all frequencies where SSB phone is also allowed. James T.

Re: [AMRadio] AM IARU Region 2 Bandplan
I haven't attempted to formulate a response yet, but two things immediately come to mind. One, the bandwidth issue. The Region 1 plan specifically accommodates AM on any phone frequency despite nominal maximum bandwidths posted in the chart. This is conspicuously absent from the current Region 2 plan. Two, 40m. Although this would take FCC action to correct in the USA, phone/cw segregation should be more closely aligned with that of the other regions. Specifically, in light of the removal of (most) broadcast stations from 7100-7200, the N. American band plan should accommodate phone down AT LEAST to 7100 kHz. (Most other Region 2 countries are already operating phone well below 7100 anyway). This would apply immediately to Canada, Mexico and other countries in the Americas, since nearly every country in the world, except for the U.S., long ago phased out government-mandated subbands. It is ridiculous that 25% of the newly-vacated frequencies are off limits to US phone operators, yet at best there are hardly ever more than a half dozen or so CW/RTTY/data QSO's on 7100-7125 at any given moment, while 7060-7100 remains under-used by U.S. non-phone ops as well. SSB ops are fond of complaining about AM activity in the vicinity of 7160 because of the limited band space to operate phone in the newly vacated segment. We need to be thinking of a petition to the FCC to further expand the 40m phone band.

Re: [AMRadio] AM IARU Region 2 Bandplan
This is irrelevant to the current proposed action on the table. If you want to write a proposal to the FCC, have at it. It doesn't take a broad consensus of amateurs to push a proposal before the eyes of the FCC. Pete, wa2cwa On Fri, 5 Mar 2010 13:36:07 -0600 D. Chester k4...@charter.net writes: Two, 40m.
