[AMRadio] The zeal to eliminate AM mode on the amateur bands.
Having only been active on AM mode for just two short years, I consider myself to still be a newbie, still not understanding the zeal and fervor by some in the amateur community to eliminate or totally outlaw the use of AM mode transmissions in the MF/HF amateur bands in the USA. ...As quoted by one person like using spark-gap. I look at AM communications as just one of the earlier modes, something to be preserved, not cast aside. Could someone more familiar with the issue please give me a better understanding of why these people are so intent to get rid of this mode? 73, Mark Cobbeldick, KB4CVN Monroe, VA __ Do You Yahoo!?

Re: [AMRadio] Don't forget 10 Meters
From my QTH in Central Virginia, I worked via 10m into CT and Dallas-Fort Worth last week during lunchtime while in the mobile. Condx finally starting to improve. 73, Mark Cobbeldick, KB4CVN Monroe, VA FM07jo Message: 1 Date: Sat, 21 May 2005 09:16:34 -0500 From: Mike Duke, K5XU [EMAIL PROTECTED] Subject: [AMRadio] Don't forget 10 Meters To: Discussion of AM Radio amradio@mailman.qth.net The 10 meter E season has begun. On Thursday and Friday of this week, I made an AM contact each day near 6 PM on 29.0 with my HTX10. Yesterday, I heard 3 other AM stations, but had a dinner engagement, and was unable to stay near the rig. Remember to check 29.0 often during the summer E season. Don't just listen; occasionally identify or call cq. If we all only listen, we'll all hear nothing. Also remember that if 10 is open even marginly, 15 will also be open. See you on the bands.

Re: [AMRadio] 10 meter AM
Thank you to everyone who replied. I have a good place to start. Going to order crystals for 29.0 and 29.1 next week, then start the retuning after they are received. An old ham friend of mine in Georgia just gave me a RS HTX-10 mobile, which also has AM. I will try playing with that until the CB to 10m conversion is done.But tube rigs still sound better to me! BTW: Been seeing a lot of good DX on the FM end of the 10m band lately. I run converted commercial gear on 29 MHz FM, and run the 10m fm list on Yahoo http://groups.yahoo.com/group/AR29MHz-FM/ but have been wanting to play on 10m AM too. This will be a good start. I work professionally in the two-way radio business as a Master Technician at the factory in Lynchburg, VA, and know all too well how easy it is to get burned-out and not want to tinker with amateur radio as a hobby. (I was that way for years...) But I grew-up listing to stories recounted by my Elmer (Santiago, WA4KSD) of the 50's heyday of 10m 6m AM Phone. By mostly staying off the 2 440 repeater bands and doing something a tad different, the hobby is still fun. 73, Mark Cobbeldick, KB4CVN Monroe, VA __ Do you Yahoo!? Check out the new Yahoo!

[AMRadio] 10 meter AM
I am active on 10 meters (FM SSB) for some time, but have never played with AM on this band. Recently a ex-CB (no-code) Tech neighbor gave me several functional older tube-type crystal controlled CB radios, which I am considering converting some over to 10 Meters for AM. Being crystal controlled, what frequency(s) should I have rocks for? IE: Calling frequency Thank you in advance... 73, Mark Cobbeldick, KB4CVN Monroe, VA __ Do you Yahoo!? Check out the new Yahoo!

RE: [AMRadio] Converting old 1.8-4.0 MHz AM Marine Radios
WOW !!! Thank you to everyone who responded via postings and private e-mails. In answer to Jim's [WB2FCN], I don't have any data on the radios...yet. Let me explain: I work in the land mobile two-way radio field as a Product Support Engineer Master Technician at the factory in Lynchburg, Virginia. One of my customers (...and an old ham friend) is the senior tech at large marine dealer/service shop in Southern California. The other day while discussing a technical issue with a radio we got chatting about 2 MHz marine radios, and the old AM Radiotelephone rigs. He mentioned that he had a 20-foot shipping container's worth of the equipment sitting in his warehouse, the business owner would love to get rid of! He had pulled a couple of them out recently and they still worked OK! ...Would I be interested in 1, 2 or more of them? He is planning to move to Eastern Tennessee in the not too distant future, and would not mind putting a few of them onto the moving truck for me. This is what prompted my question to the list. I have a somewhat special place in my heart for AM Phone, and 160 Meter/2 MHz marine radio. When I was about six or seven, I converted an old (tube) AM Band table radio up to 160m band and the lower portion of the 2 MHz marine band. The Loop Antenna was glued inside of the pressed paperboard rear cover. I wrapped several turns of insulated hook-up wire around this loop antenna and ran it outside to a 100-foot longwire and a ground. Growing-up down in Miami(Fla) and over in the Bahamas, I had tons of radio traffic to listen to from all over the SE USA and the Caribbean! Later in the 1970's when folks started converting over to SSB, I even built a BFO for the darn thing. Hearing about all the goodies he had stashed, made me remember the old days, wondering if I could recycle one of these fine old marine radios over to amateur service. 73, Mark A.

[AMRadio] Converting old 1.8-4.0 MHz AM Marine Radios
Hello to all, I have a source of old AM marine radios originally used on the 2 MHz marine band. These radios still function correctly, most of the 150 watt output level, with a few 1 KW models. Has anyone attempted to convert any of this type radio for use on the 160 meter or 75 meter bands? ...Is it worth the effort? 73, Mark Cobbeldick, KB4CVN Monroe, VA ___ Do you Yahoo!?
