At the moment, the usual frequencies for operating SOTA on the 15, 20 and 40m bands are aproximately these:
15/20m: around 21/14.062 ± 5 KHz for CW and 21/14.300 for SSB ± about 40 KHz
40m: around 7.032 ±5 KHz for CW and 7.150 ±25 KHz
I mainly activate on:
- 30m, which is CW only, so no problem, and
- 20m, which is CW and SSB, and I find a bit tedious QSYing from 14.062 to 14.300 with either of the small knobs in my FT-817.
Sometimes I’ve thought of changing the SSB frequency to some around 14.110, which would be closer to the CW segment. The QSY between CW and SSB would be faster/easier between 14.062 and 14.110
This would also apply for 21 MHz.
On 40m we could possibly use 7.045 for SSB, which is pretty close to CW’s 7.032.
On 10m it’s not posible, I’m afraid, as the band is much wider and I recall the frequencies near the CW segment are for beacons.
Are there any license related reasons for using current so distant frequencies for CW and SSB on 15, 20 and 40m?
Are there any good reasons for not trying what I’m suggesting about operating on closer frequencies for CW and SSB?
Having closer frequencies for CW and SSB would also give us the chance to have best adjusted antennas for a frequency in between 062 and 110, which would give us a better SWR on both modes.
