Back to Monitoring 10m a Bit More.

 In the energy crisis (which is likely to continue for a while, I have reduced the number of radios used for monitoring.

The daily operation runs a 2m/70cm transceiver (the IC-910 at the moment) scanning FM frequencies and making the occasional local QSO. The drawback is the rather high power consumption, about 2A at 12V, so about 25W, just for reception. At the moment the 910 is running on mains power, as the only radio running daily. I may change this into another (FM only) transceiver consuming less power, and still running 2m and 70cm. I do have another (FM) transceiver monitoring a local frequency on each of the  2m and 70cm bands. A mobile rig using about 500mA.

Most of the remaining daily activity runs on my small solar power system:

24/7 monitoring of the FT8 frequency on 50MHz, running an old ("handheld" brick) transceiver with 120mA current consumption.

Day long monitoring of diverse HF frequencies, mostly CW, and a bit of QSOs with 5W, RX current consumption about 300mA

Day long monitoring of 28.200, the frequency on 10m for the International Beacon Project, at the moment using my old IC703 with 600mA current consumption. As soon as I set the 703 to 28.200 the 4X6TU beacon was received with good signal strength. Yes, 10m is open.

There is a possibility of reducing the power consumption of the monitoring system, but this requires some building and other activities. At the moment I am working on getting the heating for the house, so I am ready for the winter, because, as they say: "Winter is coming!"
