Marconi TF1152 RF Wattmeter

In line with this month’s focus on all things Wireless I am covering a vintage instrument that has given me many years of excellent service and peace of mind at a very small investmentindeed. If you like to work with transmitters, large or small, the most important thing to have on the test equipment shelf is not a hefty power supply, not a spectrum analyser, not Teflon trimmer tools or any new-fangled bit of LCD multimeter.
