Has anyone requested that they help? It's not the ARRL's job to fight violation rulings made by the FCC. The ARRL can petition the FCC concerning PROPOSED rules; they do a darned good job lobbying. But I don't recall the ARRL interceding for a ham that's been NAL'd. This guy just needs a good lawyer. Concerning whether the ARRL actually does anything useful, I suggest you study the history of ham radio and the role the ARRL has played in preserving our wonderful hobby the last 70 or so years. The ARRL is older than most hams. Besides, they put out a darn good magazine.

From the buzz characteristic of the noise I guessed it was power line noise but I could not explain why it was not constant across the band. Next, I connected an oscilloscope to the audio output of the receiver. Expecting 60 Hz, I synced the scope to the line frequency. Effectively I had a stable pattern of spikes but more than two spikes by cycle of the line frequency like if I was receiving noise from two phases of the power line. No big surprise there. The surprise arrived when I tuned the receiver across the band. The position of a set of spikes moved relative to the other set until they superimposed. Past that point the noise would disappear on a part of the spectrum and reappear further. (I do not remember the details.) Can anyone can explain the phenonena? Meanwhile, I am going for a power line noise hunt. 73 de VE2AEY Jean-Marie ------------------------------ Date: Wed, 24 Nov 1993 00:41:50 GMT From: ucsnews!sol.ctr.columbia.edu!howland.reston.ans.net!torn!nott!cunews!revcan!rubicon!cowan@network.ucsd.edu Subject: TM-732A mods To: info-hams@ucsd.edu Thanks to all that responded. 73 de VE3OIJ ------------------------------ Date: 22 Nov 1993 22:03 PST From: nntp.ucsb.edu!library.ucla.edu!news.mic.ucla.edu!unixg.ubc.ca!erich.triumf.ca!bennett@network.ucsd.edu Subject: Use of HT for Marine & GMRS To: info-hams@ucsd.edu In article <93326.174137MGB@SLACVM.SLAC.STANFORD.EDU>, <MGB@SLACVM.SLAC.STANFORD.EDU> writes... >I have seen various discussions about using the out of band frequencies >on a Amateur band tranceiver for Marine, GMRS or other services. >If a person is an Amateur, and also holds liscenses for other services >can he/she use their amateur radio on those services.

However, unlike the current thread re operation on a sherrif's channel, if you have a station licence for, say, the marine VHF service, you are very unlikely to be caught and prosecuted for using a modified ham rig on a marine channel. Please note that I do not advocate the use of unapproved equipment. I use my TH77 as a second marine receiver on occasion, and if necessary would use it as a "lifeboat radio" in an emergency.
