Hermes in motion

 Finally got a few minutes to put together my new SDR radio. I collected the TAPR Hermes Transceiver board mid week http://openhpsdr.org/hermes.php. The PA and enclosure are  from Apache labs https://apache-labs.com/ and had been here for a while. To Interface them together 2 connectors have to be soldered, a resistor removed and a couple of cables hooked up. It is a bit crowded in the box!

As can be seen it can select 3 antennas, an ethernet interface to the outside world (can be GIGE), can be locked to GPS, has a low level transverter output operates 10kHz to 55MHz and produces around 15W

It arrived with V1.8 software but I upgraded it, through the ethernet port to version 2.0 which was released a couple of hours earlier

I hooked it up to the W5WC dual receiver version of Power SDR which allowed monitoring of 500kHz and 40m as can be seen from the following:-


There is software available that allows monitoring 160/80/40/20/15/10 all at the same time with panoramic displays for each although you cant listen to all at the same time

VK6APH has also created software to use the device as a 55MHz VNA allowing transmission/reflection to be measured and displayed as a graph or a smith chart
