If all goes well, will be selling my R8500 and R75 in a couple of days. So back on the hunt. Have owned the 705 in the past. Never owned the 7300. Trying to read up on the 7300 as far as filters and such. Both are close in price. Thought about the 8600 but a bit expensive, plus I already have a SDS200 and 15X. Am looking at software I can connect one of these radios to a computer for decoding CW, etc. If you have used either or both, would appreciate any comments or suggestions. Thanks.
