I recently received my December issue of The Spectrum Monitor (TSM). I really look forward to getting this publication each month! I am a charter subscriber since its beginning in 2014. It is very similar to the former Monitoring Times magazine which discontinued publication back in 2013.Check out TSM on their web site at: http://www.thespectrummonitor.com/index.aspx
TSM is usually around 100 pages and is packed with the latest on Amateur Radio, Shortwave, Scanning, Satellites, Radio/TV, Vintage radio, etc. The news and articles are always up to date and relevant. TSM is available only in PDF format and can be read on any device capable of opening a PDF file. I read TSM both on my tablet and PC. I also occasionally print out interesting articles that I might need for future reference in the shack. It's probably the Best $24.00 that we spend each year on this hobby!
The TSM publisher, Ken Reitz KS4ZR, is the former managing editor, features editor, columnist and feature writer for Monitoring Times. As well as a former feature writer and columnist for several other publications. TSM has some very experienced and talented writers that do a great job of covering many interesting topics each month!
