These things sure don’t like high SWR, as smoke came out of mine once! I finally realised I was transmitting on 28MHz into my 50MHz yagi…
The FT-50R will drain it’s battery rather quickly, even if the transceiver is turned “off”. This mod will reduce the “off” current drain of the transceiver.
We take a look at sweeping an M2 23CM35 yagi for 1296 MHz using a Windfreak SynthNV USB powered and programmed RF Signal Generator / RF
I was looking into using a single VK3XDK PLL Synthesizer for both my 2.4GHz and 3.4GHz transverter systems. ie; sharing the one PLL for both bands,
One thing that became apparent when using a single XDK PLL board in a dual-band 2.4/3.4 GHz transverter system, is that the PLL’s limitation on producing
This describes how to modify a Yaesu FT-817, so that the +12V appearing on the accessory connector switches on and off with the radio. Normally, the
Kuhne provide a PLL Lock status LED on the PLL board of their G3 transverter modules. This LED is inside the module, which is great when
NEVER use VOX operation when using RF Power Amplifiers. It should be obvious why. The transmitter, and the PA will switch on after audio modulation is detected. You
When is a transfer relay not a transfer relay? Normally, a transfer relay can be considered as a “double change over” device, but not all transfer
I was caught by surprise out in the field the other day, when my new Kuhne MKU 10 G3 432 appeared to not work. But it
Expressions of interest in obtaining a ThunderBolt Display will be closing soon. This third production run will be the last. Please contact me, if you would like
My Down East Microwave Inc 3W 10GHz amp kit arrived in the mail recently. It was ordered on 14/4/11 and arrived 20 days later on 4/5/11.
Here’s an interesting rainy day project for microwave enthusiasts to experiment with. And as luck would have it, it poured down today! From Kent Electronics it’s
This 5.7 GHz Power Amplifier originated from the Wellington VHF Group some years ago, and the information below is a compilation of information posted on the
Here’s a rundown of my Trimble Thunderbolt GPSDO project. It provides an accurate 10MHz reference for the transverter Local Oscillator PLLs. The existing Thunderbolt mounting holes
