Some of my log\nrecordings are a great argument for full-duplex; e.g. I can \nhear clearly and immediately if a letter got lost\nand I need to repeat my grid a second time --- especially \nrunning 5W. The FT530 does not de-sense and I can\nclearly hear my own downlink in the headset.\n\nWith the pre-amp, clean sky and polarization match, SO-50 is \nfull scale into the FT-530 RX. Where it helps is\nwhen I have trees and a less than optimal horizon (pretty \ncommon in New England).\n\nI ran the same on AO-51 and AO-27 and could copy right down \nto the horizon, easily working into Europe.\n\nBill W1PA \n\n", "attachments": [] }
