SRF-M37V and SRF-M37W-Performance differences?


Gary DeBock
 

Hi Rob,
 
     As explained in the full review of the SRF-M37W in the 2008 Summertime Shootout (posted in the ULR file section of DXer.Ca), its selectivity (or lack thereof) is identical to that of the SRF-M37V.  In fact, all the AM circuitry is unchanged.

New and been lurking awhile. Have a SRF-59 after finding this group.

Digital display would help, so interested in SRF-M37; and I see that
the V is replaced by W model. I Have read shootout about selectivity
issues in the V. Wondering if anyone knows if the SRF-M37W may be
better in selectivity or any other performance issues, in am band?

Also, what reference book(s) can someone recommend to identify am call
letters, frequency, location of North American and/or World medium
wave, AM broadcasters?

Thanks,
rob

Rob, as far as books are concerned for IDing MW AM stations the best for worldwide use is the WRTH 2009 annual. It is my "bible" and constantly by my side. See:
http://www.wrth.com/ - its also available from American booksellers and online at Amazon etc.

However if you are resident in the USA you may want something more comprehensive and there are various huge lists put out by various clubs and bodies - maybe someone else can help you with those addresses.

Also there are various web resources, my favourite being:
http://www.radio-locator.com/ and others like:
http://topazdesigns.com/ambc/
plus more that others might give you.

Good luck and good listening

John and Rob,

A word of warning about radio-locator.com: Their database of Canadian stations is extremely out of date. In the first 200 stations they list for Ontario, I found 13 errors. These are such simple things as stations listed on MW that moved to FM as much as 15 years ago and stations that are not listed that have been on the air for about the same period of time. Other changes not in the database are more recent such as format changes or moves to FM.

In other words, don't expect accuracy.

Hi Rob:

While the M37V is not the worst selectivity-wise (the true "F" in this
category is a Radio shack portable currently available, which is so bad it
only tunes in about 8 different stations, one every 100 khz or so!), in
stock form the M37V is tough to use in an urban environment. However, if
you live outside of a strong RF environment, then it works very well, and
Alan Willie in Newfoundland has set a lot of records with his stock unit.
I have an M37V with the filter replaced which transforms it into a new
radio, but if you are not up for that kind of technical task, then the
M37V/W may not be for you.

Kevin:
Appreciate the clarification of the M37- live in urban area
(Buffalo,NY area) and have second home 10 miles away- probably not
far enough. And have not soldered in 40 years! May get back to tech
stuff, but not right away. To bad I just missed out on Eton100 NOS
stock sale at Durham radio.

So now considering Sangean 400W- shootout results looked good- anyone
want to comment if they have one???

John:

Last week I looked up WRTH 2009 annual and was not out yet- will
check again online. I did go to bookstore that had Passport to World
Radio 2009- but was ALL SW stuff.

I have noted the links you gave.

Thanks so much
