I shall be on 40 metres today, International Marconi Day. Hope to work you.

The latest addition to the radio room. A Racal RA-1772 communications receiver. Lovely piece of kit. 😃👍

I had to replace the lithium battery on the Kenwood TS570D. Easy to get to, fortunately.

I'm hearing RTE Radio One on short wave. 15770kHz. Good signal on the south coast UK. Is this being relayed by someone?

@ham_nc_160m_10m Indeed! Very expensive!

@G4NSJ Looks like it would have been an expensive when new.

I’m pleased with this oscilloscope, although a knob is missing. Donated by my friend Roy. Works well!

I’m still calling on 160m most nights. JS8 Call 1842kHz at 1900 UTC. There are now two of us chatting most nights so, join us if you can. 73 Ray.

@ham_nc_160m_10m @HamRadioDX Thanks for the info, very interesting.

@G4NSJ I used to use an SWR meter when configuring antennas. Now I use a NanoVNA (thank you @HamRadioDX for the demonstration video) and the SWR meter built into the radio. Here are images from the most recent adjustments of my 155 foot End Fed Random Wire Inverted-L. The sweep and PSKreporter image are for 40 meter FT8 running about 5 watts between 11:30 AM and noon local. NanoVNA-Saver is used on the computer to monitor the NanoVNA continuous sweeps. Zoom is installed on the computer and phone so I can monitor changes in real-time. The coax is used as a counterpoise. Twelve clamp-on 31 mix ferrites were initially installed and moved from the antenna end of the coax to the radio end of the coax. When a satisfactory sweep (always a compromise) location was determined for 160m thru 10m the ferrites were removed one at a time while continuing to monitor the sweep. Three clamp-on ferrites provided the best economic cost for performance. An outdoor extension cord safety cover is used to protect the ferrites from rain, snow, insects, etc. I've had one installed on another run of coax about a month. The ferrites have been through several rain showers and have remained dry and bug free. Various styles and size covers are available on Amazon from many sellers.

@ham_nc_160m_10m Thanks, that’s interesting. Most JS8 activity here is on 40 and 20. There are a couple of us on 160. Cheers, Ray.

@G4NSJ In the US there is very seldom anyone on 160 JS8. Even on the other bands you mostly see HBs. I see the most activity on 40 & 20. Usually, a few FT8 on 160. Most US stations seem to be on 40 thru 10 on FT8.

I was on 160 metres last night with JS8Call. Plenty of FT8 but no JS8. Such a shame. It’s a great keyboard to keyboard chat mode.
