New transceiver Yaesu FT-920

It was time for replacing my old Kenwood TS-850 transceiver. The TS-850 has served me well, but it was getting old, and a new HF transceiver was in the pipeline.

I found a fine offer on the Danish second-hand site ham.brugtgrej.dk. An Yaesu FT-920 was for sale in mint condition. The FM-unit and a 250 Hz CW crystal filter were included. I studied the FT-920 reviews on eham.net before contacting the seller. I bought the transceiver on the spot, and transferred the payment via web banking. A big parcel arrived two days later.

The FT-920 is a medium-class transceiver - it is not a contest machine. As I only participate in contests a few times a year, this transceiver will probably fill my needs.

Here are some pro & contra statements regarding the FT-920:

Pro FT-920

  • There are two VFOs with each their own display 
  • There are 2 antenna ports and one “receive only” port.  
  • The DSP works at audio frequencies and can be switched off
  • The noise blanker is excellent
  • The CW operator is spoiled with functionality
  • The RF output can be turned down to the mW level
  • The 6m band is included (100 W output)
  • The RX is pleasant for long-time listening (according to reviews)


Contra FT-920

  • No 2m/70cm band
  • No dual receiver
  • No option for SSB crystal filter
  • No dedicated transverter port 
  • No band-scope 
  • The cabinet is big and heavy


My new transceiver Yaesu FT-920.
Time will tell if my new purchase turns out to be a success. Right now, I intend to work JT65/JT9 on HF and collect countries for my future QRP DXCC award.

Moving the VHF antennas

My current VHF antenna system is positioned just between my own house and my neighbour's house. Both houses are terrace-houses, and a part of the antenna is above my neighbour's roof.

I am working to extend my VHF antenna system in order to operate EME, and more space will be needed. That is why I have decided to move the VHF antennas towards the center of my garden.

In the picture below, you can see how a 6 meter long steel tube (diameter 50 mm) will serve as the lower part of the antenna mast. The upper part (not mounted yet) will be a steel tube which is going to be rotated by a Yaesu rotor.

The new antenna mast.
The construction is to begin ASAP. I will report how the work is progressing in a later update.
