75/80m split or no split ….
I was operating as CT9L for the CQ WPX SSB. I noticed that there was a little bit of misunderstanding on 75/80m I guess. I was listening on my TX frequency but also asked stateside to call me split up at 3.827. I got a lot of callers from the US that tried to work me on my TX frequency. The problem was that with the EU QRM 20 over S9 it was hard to copy any DX, where I had a good copy on weak signals S2-3 on the split frequency.
My point is, even if your license permits operating below 3.8. If the DX is asking for split it is a big benefit for you trying the split frequency unless you are able to pounce a 9+30 Signal into Europe.
Looking forward to work you again in CQWW SSB from CT9L

This used to come up a lot on 40M... If possible I would call on tghe DX frequency because my beam was useless above 7.200 (high SWR)... If necessary I would call split at reduced power and hope I didn't fry the forty-shorty! On 75 I usually call on the split listening frequency.

Need keep 75M splits as close as possible because some using antennas with only 75-100kc usable bandwidth. 40m splits not usually as critical.

Working split when you NEED to is fine, but we make enough enemies in the phone band when we are working ON frequency, and working split makes things that MUCH worse. It's one thing on 40M when BC is the primary QRM and there are few QSOs on the band. It's another thing entirely on 75M, when the band is full of QSOs. You may not hear those QSOs on your end, but they sure do hear us. This is VERY bad manners, and these guys have every reason to be angry at us.

As WV4I said, the bandwidth is so narrow on my 75m antenna sometimes there is no other choice. Best thing on 75 is not to have really wide splits.

A high SWR should not be an excuse. Before the contest add an antenna tuner that can be switched into the feedline. No antenna tuner? Then look at an "L-Network." There are eight of these, but any given antenna will probably need only one.
Another trick is to make your antenna out of 'fat' elements. For example, a vertical can have two wires spaced from a mast by 2 feet. With everything electrically tied together at the feedpoint and the top, this will almost 'look like' a four foot diameter vertical. This will greatly increase the bandwidth (and allow the antenna to be a bit shorter).
