From everything I read

It seems like F.M. Radio will be going away in the near future. I currently have a mint Mac tuner that I don't use but it looks nice on the rack. If F.M. Radio does go away as expected do you think the value of this piece will drop like a rock? The only thing the piece has going for it is that it's a vintage Mac piece and there seems to always be a market for vintage Mac gear.  On the other hand if it can't be used will people still want it?

I imagine that F.M. radio will eventually crawl under a rock and die,but this will not happen within most of our lifetimes. When that death does happen it will be self inflicted and welcome, as 90% of commercial radio deserves this fate. The saving grace of the F.M. is still the non-commercial and institutional sponsored stations that offer a welcome alternative to commercial stations.For that reason i would keep my receiver and i would use it as often as possible to exercise that vital link of the dedicated and informed to the audience that craves knowledge and information.
   Especially the music programming of your local non commercial station that offers it's airwaves to the collectors and music lovers who dedicate themselves,without recompense,to spreading their knowledge and sharing their collections with the public.This is a rare,and getting rarer, unfortunately.
    I think we will lose a lot when this eventually goes away,or shrinks and is overshadowed by the easy internet access to music.
    The weak links in the music programming of XM/Sirius are many,but it does provide a great variety of music and some earnest commentary on it.
   Now is the time to go give your FM receiver a big hug and listen to those local goons,the fanatics of Bluegrass,the garage Rock heads,the mouldy fig Jazz impresarios,the hipsters and the flipsters,the high and flighty  guys going for Baroque and the endless drone of industrial and independent small press Rock that survives despite the drooling D.J.'s. It's alive,it's radio,it is the voice of actual people who make mistakes and don't really care because we all make mistakes. We need it, and it may be the last hearth we may have to sit around,one on one.
    So save your radios.Use your radios.We need them now more than ever.
It easy actual a tuner not a receiver. I really like the way you explained that. Thank you.

Much like obsolete cameras for which film is no longer available, an FM tuner, in a post FM world, would be nothing more than a static display piece. 

I suspect that initially, the value could plummet but in a 100 years, it may be worth some real money. 

Feel better now? 
Within five years that Mac will become just another dust collector. Sad but true!
Just did some research. Norway will shut off FM in 2017. Some other European countries might shut it off in 2022. In US it would take an act of Congress to end FM, and with all the money at stake, especially with smaller markets unable to convert to digital, most think it will be a long long time before the US ends FM radio. On the other hand, I have a Don Scott modified Mac and Luxman and hardly use them anymore. I sold a D Scott modified Sansei and the price was lower than the past.
I love my tuners, but really don't have great stations here, and have trouble listening to announcers and commercials...
The projected and possible shutdowns of analog FM in some European countries signify nothing whatsoever with respect to the future of FM in the USA, Canada, and many other countries. Those European countries have adopted a digital broadcast standard called DAB, which as I understand it does not provide for simultaneous analog and digital transmission. While in the USA the standard that has been adopted is HD Radio (HD just being a trademark, which does NOT stand for "high definition"), which can be and is presently being used by many stations to broadcast a hybrid digital + analog signal over the FM band (the analog component being receivable by an ordinary FM tuner or radio).

While under the HD Radio standard digital-only broadcasts are possible, I’ve seen nothing to indicate that abandonment of analog FM or hybrid analog + digital HD Radio broadcasts is anywhere on the horizon in the USA.

Also, if and when that were to ever occur, I wouldn’t be surprised if some companies were to produce converter boxes, that would receive digital broadcasts and convert the signal to analog FM that could be listened to with an analog FM tuner. What the resulting sound quality would be is anyone’s guess, of course, but given the relative insensitivity of FM to noise that may be riding on the signal I wouldn’t be surprised if the results turned out to be pretty good.

I agree that FM broadcasts are not about to vanish anytime soon, but the sale value of FM tuners has declined, particularly for higher end models.  There are exceptions, but there are less people chasing the same number of tuners, hence a decline in prices.

Thank you for the erudtion -- your contributions are fantastic!  :-)

Happy Holidays and New Year!

Americans spend a lot of time in their cars. Yes we have sirius, xm, podcoasts and streaming bluetooth but my guess it will stay with us due to cars and maybe somehow real community radio will come back when these corporate stations and the all talk npr need a refresh.  
Sam (c1ferrari), thanks very much.  And all the best to you and yours for 2016!

I agree with those who suggest that FM won't be going away anytime soon. However, I am a bit biased in that I am using an Accuphase T-303, and really enjoy it.
