Shack re-establishment

With the QTH move all done, I have started to get my shack set up, the shack computer is operational but requires network connectivity and at present the only network feed to that room is for my web server, so I am looking at getting a switch in order to run the shack computer, the NAS box and the server off wired ethernet, I don't intend to set up wireless at all for the NAS and the shack computer will only be on wireless temporarily until an Ethernet switch arrives which will probably be around pay day.

The radios are working, I put the 2/70 antenna on top of an old computer case first on the top of my shelves, which I had assembled previously, SWR was very high but not dangerous to the radio, so I had a theory it may work on the radiator, so I attached the magnet there and low and behold the SWR dropped considerably, in fact the needle is not moving on 10 watts on 2 metres and is at most 1.4:1 on 70cm, which I find incredibly impressive for a compromise antenna, then came the turn of my CB antenna, I placed it on top of 2 old computer cases (one of these being one I used for the 2/70 antenna before placing it on the radiator), the mismatch on 11-metres was bad, at the bottom end was well into the red on the SWR metre but an improvement on the old excalibur, the top end (UK40 channel 40) was about 2, suggesting the antenna was far too short, theory, use it for 10-metres, plug it into 10-metre rig with a power output of around 10 watts, in the FM segment the SWR was very low, suggesting it will tune across 10-metres, which I will give a go at a low power at a later date.

I am so far impressed but as time progresses I intend to hide a couple of wire antennas in the nearby trees if possible to get me on both 10 and 11 metres at home, I already have my T2LT which has seen some but not a lot of action, and some kind of wire antenna for 10-metres could also be made, worth investigating

Due to past abuse and the ongoing issues that left me little choice to reduce time on twitter and IRC I have taken the decision to keep comments disabled indefinitely, apologies for this
