-70cm Ground Plane

+### 70cm Ground Plane
 
 As seen in ARRL Antenna Book etc. Using a N connector instead of the traditional SO-239 connector. Very easy build, did most of it sitting on the sofa watching TV.

+The crimped ring terminals make it easy to remove the groud radials for transport. They bend to so can be used to adjust the antennas impedans. At 90 degree angle the antennas impedans should be around 30 Ohm and raise to about 50 Ohm if the radials are at 45 degree angle.

+A few shortwave antennas I tried with very little success. After a while I discovered where I live have severe interference pretty much across the whole HF spectrum and very little I can do about it. Shortwave on a hold until move somewhere else.

+### Remote Interface
+
+This is a 7-pin DIN plug used to connect to an external linear amplifier or transverter. It has an ALC input and a T/R-relay connection. The ALC input is biased down to -10V for minimum power output.
+
 ### Serial Interface
 
 To connect to a computer the TS-680 needs the IF-10C module installed and IF-232C interface and level converter. They are out of production like the transceiver itself and hard to find. The latter also is a bit old fashioned nowadays when USB is the norm.
