OE5FGL ... Propagation


This diagram shows approximately how much chance for good short wawe QSOs, Earth-Moon-Earth QSOs and more today regarding to sun activity and more.


Index


About Muscles: By convention (by hamspirit, not by law) reserved space for low power (30Watt max) digital QSOs.

CW, SSB and RTTY in neighbourhood usually use much higher Tx-power, override the decoders and interrupt running QSO's. Indded some "Data"-OMs also make QSOs with much higher Tx power than 30 Watt.

Other typicak Data-modes are OLIVIA, THOR, MFSK, HELL and CONTESTA. Usually they take 250 Hz bandwidth up to 1000 and they are operated at the upper end of the PSK areas. I like to collect experiences with experimental joyful OM's out of contests.

PSE TAKE CARE:

1) many radios use the carrier frequency for adjustment purposese, eg. to "tune" the antenna. Eg. if you "tune" the antenna on the PSK-40m band, you blow up to 100W carrier at 7.040 in the air. At a beginner I did not recognize that :-(

2) LSB at 40m means that the side band at your 7.080 spreads a lot of power into the JT65 and JT9 area at 7.0799 and below band. The JT65- and JT9 band is fixed but you can move a few kHz higher easily with your LSB-QSO.

3) JT65 and JT9 signals are weak, often hidden behind the noise curtain. The same applies to WPRS signals. We PSK-OM's and the SSB-, CW- and RTTY- - OM's shall not feel the "frequency is free" in this area when we hear nothing and we see only noise on the waterfall. It is likely that there is a DX-QSO hidden behind the noise. PSE keep the area free.

If anyone destroys my QSO, intentionally or as a bully, he/she also destroys the QSO of my nice QSO partner.
The DX-code of conduct is no battle.
The main issue, the point for hams: The weak modes above cannot use another area but SSB, CW and RTTY can move easily.
It is like beating a dog on a chain.

I found another area of "HAM SPIRIT- PSE KEEP FREE AREA":
