I received the LED SWR indicator (QRP only!) and the Digital Dial from QRP Kits today. Of course I had to assemble them!
The Digital Dial is a 4 digit frequency counter with some interesting features. It has a maximum frequency display of 45 MHz (just fine for LF/MF) and runs on a 9 volt battery.
I’ll be creating a custom crystal checker / frequency counter / digital dial combination with this kit. One portable box for my QRP transmitter projects. I can also take it to hamfests for checking any crystals I wish to purchase as it will fit in my coat pocket.
Of course I need more bits to finish this off but that’s part of the fun.
The LED SWR indicator is used to tune up QRP antenna systems. A quick visual indication of 50 ohm match when the LED goes out (or dim). It’s very small and extremely light weight for backpacking adventures (SOTA anyone?). This one is destined for the 1Watter, 160meter xcvr enclosure. I left out the LED for now as I’ll be measuring to fit once the PCB enclosure is complete.
This, of course, will force me to start construction of the PCB enclosure. I don’t have a shear so other measures will be needed to cut the PCB. I’ll let you know how that works out!
