Comments[edit]

Note, there is a lot of noise right now about the legality in the USA of wireless mics, and what's legal or not. The rules are in a state of flux and many web pages have been put up that contain incorrect or old information. I have put some of the current info in the USA section of licensing, when in doubt please refer to the FCC pages in those links. Altaphon (talk) 01:02, 22 January 2010 (UTC)[reply]

One problem with this article is that there is no discussion of how any of the original wireless microphones were powered. This seems to me to be an egregious omission. I would like to know what kinds of power or batteries were used in these systems. — Preceding unsigned comment added by 97.127.198.64 (talk) 01:18, 12 September 2018 (UTC)[reply]

Who was first?[edit]

I think it's incorrect to state that Shure claims to be the first, and I'm not sure how important it is to define who was first, as it would be difficult to define what a wireless microphone is. Even Shure says that the question is up for debate in the article at this link: http://www.shurenotes.com/issue22/basics-history.html synthfiend (talk) 17:30, 22 April 2011 (UTC)[reply]

The question of who was first is a messy one, with a number of claimants. The earliest mics were not very practical, having a heavy transmitter pack worn on the back rather than contained in the body of the microphone. Each of the 'firsts' could claim some aspect of being first, such as first self-contained wireless handheld microphone, or first use at a specific type of event. Rather than pulling the Shure bit, I would augment it with more detail. Binksternet (talk) 18:15, 22 April 2011 (UTC)[reply]

A patent issued to Nady Systems, Inc was filed for in 1976. On October 11, 1983 all 8 claims of the patent were overturned, and the patent cancelled, by the United States Patent Office.^[1] — Preceding unsigned comment added by 64.134.70.38 (talk) 15:28, 26 September 2012 (UTC)[reply]

If you're going to change "firsts" in this article, you need to back up your claims with a reliable source. OhNoitsJamie ^Talk 15:44, 26 September 2012 (UTC)[reply]

Diversity[edit]

Does anyone have a reference for the claim in the intro text that diversity systems transmit on two frequencies? This is certainly conceivable but I don't think there is a single unit made like that. Every wireless diversity system I've seen uses space diversity, i.e. more than one receive antenna, with multiple receivers or multiple front-ends of a single receiver. Altaphon (talk) 06:23, 25 August 2019 (UTC)[reply]

Good catch. I fixed the problem by swapping transmit diversity for receiver diversity. Binksternet (talk) 07:44, 25 August 2019 (UTC)[reply]

First compander[edit]

I think Vega was using companders before Nady. I worked with Gary Stanfill (Pres of Eng. for Vega) and had helped him (he died in 2021) design many a compander wireless systems for ICRI and hazmat stuff (he eventually worked for C-AT after his tenure at Vega). Nady was doing wireless mics well after that. I recall Gary bitching up a storm about them Wamnet (talk) 22:37, 12 January 2022 (UTC)[reply]
