“My wire is longer than your wire!”  🙂

155′ with 9:1 unun.  The LDG tuner & old FT-100 would tune it 160-6 meters.  I found the internal tuner on the 7300 only handles 3:1 swr and will not tune my wire on 80 or 160 now.  Hate to use an external tuner on the 7300, so I might have to modify the antenna so it will tune the lower bands.   Maybe a big loading coil on the longwire.

Warren, the solid state digital stuff has gotten so fast now that they are doing direct conversion of RF, bit-slicing the RF directly and processing it in digital form.  This eliminates the local oscillator, mixer, and IF stages… all the stuff that adds noise and ‘birdies’ to a receiver.   My noise level went from S6 on the old rig to S3 on the 7300.
