Grant, All of this topic drift into areas non-Elecraft, (and there is a massive amount of it), is a direct result of the moderation efforts Elecraft puts into this group. If the group owners, (Elecraft), wanted things tighter, they would moderate more tightly. If they don't have staff to

I find this list way too political and mostly one sided. Could you please stop this and all political/religious discussions? Or do I have to say something against your religion/politics to stop the thread??? Thanks 73 de Jose Douglas KB1TCD > > From: Grant Youngman > Subject: Re: [Elecraft]

[Elecraft] KX2 and Icom LC-192 Backpack?

2021-01-18 Thread MaverickNH
Has anyone looked at the ICOM LC-192 backpack for compatibility with the KX2? The KX2 is smaller than the IC-705. It seems, with the extra space, cable routing could work even if connectors are in different locations. Bret/N4SRN -- Sent from: http://elecraft.365791.n2.nabble.com/

I’m not at all surprised the FCC felt it necessary to make the statement they did. And it certainly wasn’t limited to amateur radio licensees. Anyone who has ever had a good chuckle or eye-roll over the “interesting QRM” Wayne referred to, should know why. That QRM, more and more often, also

While it sounds dumb when they make such a statement, it is kinda like when here in the US of A, one of the questions on our yearly income tax forms is: Was any of your yearly income obtained illegally (or words to that affect)? Now that you have been warned, they have a better handle on what is

During my hamming of over 50 years, the FCC has never felt it necessary to threaten hams not to break the law, that is not until we have this new administration coming into control. My concern is what they will define in the future as criminal acts. 73, Steve WM6P

I too thought that this was a curious announcement, especially since it hit the mainstream media. It seems more like a "hey, check out this way to communicate." Those of us who are licensed already know this. The general public doesn't even know we exist. The few in between already do what

I see it somewhat differently and I don't see it aimed at me.  I see a benefit of FBI/FCC publicly citing the law as a good way to inform the general public that laws exist and using radios in the furtherance of a crime (ham or otherwise) is already illegal, and such crimes will be prosecuted.

My initial thought about being told not use my radio to commit a crime was surprise that the FBI wasn’t also sending me an email telling me not to rob banks. I mean, isn’t it sort of obvious that crime is bad? Victor > On 18 Jan 2021, at 2:12, Mike Morrow wrote: > > So...the FCC
