Ron's Radio Corner : DIY frequency counter
http://pa2rf.blogspot.com/2015/07/diy-frequency-counter.html
PA2RF - Radio Frequency Adventures from The Netherlands. Sunday, 26 July 2015. There is no excuse anymore not to provide your receiver or transmitter with a frequency counter. For 6 euro's I built a counter which measures frequencies from 1 Hz till 50 MHz. I ordered the "Do It Yourself" kit here:. Http:/ www.banggood.com/buy/Sku184055.html. The counter can also be used as crystal tester. Very nice design with big LED displays! 16 MHz X-tal here under test. Close look with 4 MHz X-tal under test.

Ron's Radio Corner : 60 m band
http://pa2rf.blogspot.com/2015/05/60-m-band.html
PA2RF - Radio Frequency Adventures from The Netherlands. Friday, 15 May 2015. As a result of a request from VERON ("Vereniging voor Experimenteel Radio Onderzoek Nederland") to "Agentschap Telecom", in the Netherlands there is a chance that part of the 60 m band (5250 - 5450 kHz) comes available for experiments in the near future. This band, located between 40 and 80 m, is very interesting to do (QRP) experiments. 16 May 2015 at 13:10. Hallo Ron, kan ik alvast een sked met je maken? 16 May 2015 at 23:40.

Ron's Radio Corner : More Moore
http://pa2rf.blogspot.com/2015/04/more-moore.html
PA2RF - Radio Frequency Adventures from The Netherlands. Friday, 17 April 2015. Today I ran into an interesting visualization of Moores Law;. The amount of integrated transistors versus time. Each 2 years the amount of transistors doubles. From the 4 bit 4004 processor from 1972 to the most sophisticated processor nowadays (Xeon, 15 core). 50 years ago Gordon Moore was right:. This week I drove along an old railway station that is not used anymore as station. I could not resist making a nice picture.

PA2RF - Radio Frequency Adventures from The Netherlands. Friday, 30 January 2015. The Automatic Identification System (AIS) is an automatic tracking system used on ships and by vessel traffic services (VTS) for identifying and locating vessels by electronically exchanging data with other nearby ships, AIS base stations, and satellites. Information provided by AIS equipment, such as unique identification, position, course, and speed, can be displayed on a screen. You can watch AIS traffic on the map here:.
