This video demonstrates comparative testing of i) the latest US R7 133.141.113 firmware, ii) the R7 International 128.128.114 firmware, and iii) the DFR9forNZ.

The source of K band in this test is Wellington’s latest VW Camera van operating polarised low frequency and ultra low intensity radar at 24.035 GHz.

This testing location was ideal to fully explore and compare the differences in sentivity between these two most recent R7 firmware versions. The R7 International version features user definable K band segmentation which makes it ideal in countries like New Zealand where only part of the K band is used for law enforcement.

The latest US 133 firmware features K Extended thereby can now detect the low frequency redflex. In testing around town it looks more sensitive on K band, but annoyingly so as it detects many modulated signals separately leading to many many gps lock outs being needed. In contrast the international version needs less than 1% of the gps lockouts needed for the 133 firmware. Thereby we were originally hoping to see big gains in sensitivity and filtering on the 133 to make it an all round better package.

In this test we also did comparative testing against the DFR9forNZ. The DFR9forNZ has specially designed firmware and hardware adjustment to make it ideal for use in New Zealand. Therefore this version of the detector is very different in performance to the R3 or standard DFR9. Both the R3 and standard DFR9 are limited on K band to around 24.050.
