Hi all, I was hoping to get some advice regarding my complex situation. At issue is after 18 months of not having a whole lot of luck or time I am really keen to get my 2m eme station going as I now finally have a little more time. I now have a lot of lovely kit but don’t want to blow up any of it, make the pc run the whole thing and integrate the 400 watt linear and LNA to run digital modes for eme.
The modes that seem to be best are jt65 and map65. All of this is extremely complicated and I would really appreciate any help.
Current status is that I have 2x 10 element xpols on 144.2mhz mounted with a g5500 alt/ el rotation I have 400 watts at the feed point and a decent mast mounted low noise 20+ db rx gain I have managed to get the elements on the Yagi aligned. I have the ic9700 and will be getting the 10mhz locked input to reduce drift. I have a decent sequencer on the way (HSQ5-EME/5V Version 1.5) 2 600 watt relays) and a 144 - 146 MHz High Selectivity, High Q, Low Loss Bandpass Filter as I expect that there will be quite a bit of local noise.
The g5500 rotation system also has the yaesu-gs-232a so I can run it with a computer. I am trying to keep the feed line as short as possible and have some half inch heliax but will invest in the 7/8 inch if it would make a big difference. The lines are about 50 feet long which is always going to be a lossy arrangement, although I could, on some days, run it from the base of the array.
Thank you Peter VK3BZF
