26-Nov-2019 SHF UKAC using 13cm and 3cm bands

I hopped about between both bands. On 13cm it was was nice to work Pete G4CLA again. Keith G4ODA was my best DX (longest distance) at 117 km. So my contacts were all pretty local really. I used 25W into the coax to the antenna box, so the Andew amplifier was under-driven.

On 3cm, my initial contact was with Peter G3PHO. Our usual reflection point worked well to get round the hills. Keith G4ODA was my best DX (longest distance) on this band.

The rain was in the wrong places for rain scatter.

Denis G3UVR was much easier to hear on 3cm than on 13cm, and the dish is mounted a bit lower down than the 13cm yagi.

26-November-2019 – my first contact on the 2.30 GHz NoV band

With the SG-Labs 13cm transverter in a box indoors, I can use a sub-band switch on the front panel of the box to switch between 2.30, 2.32 and 2.4 GHz. At 1870 MHz, the LO (Local Oscillator) frequency is rather low for the Microwaves Modules 70cm transverter (1870+430=2300 MHz) as I have not reprogrammed the SG-Labs transverter, so I thought the configuration might not work on the 2.300 to 2.302 GHz NoV band. I had configured the K3 with a 2300 band setting to generate the correct frequency on 10m band Intermediate Frequency (IF) feed to the 70cm transverter.

Using my Tiny VNA as a signal source, I found I could receive in the 2.30 GHz band.

I tried a contact on transmit with Keith G4ODA. It worked easily! Keith’s signal was very strong. I was using the Andrew linear amplifier producing about 50W, feeding the 40 el Wimo yagi through some metres of Ultraflex-10.

Really the SG-Labs transverter needs re-programming to give a more appropriate LO frequency, but it is nice that something works on the NoV band for the time being.

UK radio amateurs can apply for an NoV here for the 2.300-2.302 GHz band.

Ubuntu Linux: “Stopped – Unable to add document to print job” Epson ET-4500 printer

Whilst in the middle of printing,  I accidentally touched the turn-off button on the printer & after that, nothing would print and the printer status in the System Settings/Printers for my ET-4500 showed as: “Stopped – Unable to add document to print job”.

I searched the printer menus, but could find nothing to help. It just wasn’t handshaking.

I deleted the printer and re-installed, selecting Network Printer and AppSocket/HP JetDirect. In the host field I typed the fixed IP address 192.168.m.n (m.n being the numbers I assigned in the printer settings). I clicked Forward and selected the test page option.

It worked!
