One of my ham interests is meteor scatter mode. Usually MS is used on VHF bands, even on 70cm band but very few intentional MS QSOs
are made on HF bands. Now, that we are at solar minimum, it's a good opportunity to try that exotic mode un upper HF bands, 10m-15m, even on 20m. The only problem is ES, low MUF ES enhanced ionoscatter and even tropo which can be present on these bands and create some confusion. The best time seems to be in the morning, when low chance of ES and more sporadic meteors.
I've made some QSOs in HF bands, here are audio samples:
YO9HP 15m TROPO YO9HP 15m MS QRB 394 km 7 December 2007
YO7DAQ 10m FSK441 YO7DAQ 15m FSK441 YO7DAQ 15m JT6M QRB 167 km 1-3 December 2007
OE3DXA QRB 439 km JT6M 20m 17.09.2007
OZ1PIF_1 OZ1PIF_2 QRB 1264 km on 15m 14.09.2007
DL2RMM_FSK441 QRB 805 km FSK 441 15m 15.09.2007
HA8AR HA8AR HA8AR QRB 102 km on 15m 10.09.2007 - very strong bursts over weak tropo - QSO not finished.
vy short ping 200ms at 25.5s Very short (200 ms) and strong ping on 15m, decoding only "_HA" (TOL=100). In these cases, FSK441 could be a better choice.
YO2NAA_BY_HA7UL FSK441 My first FSK441 MS QSO on 15m - burst RX-ed by HA7UL 217 km 11.09.2007
HA7UL at 8s and 20s HA7UL 3s burst at 16.5s QRB 217 km on 15m 07.09.2007
HA7UL on 20m at 4.7s vy weak HA7UL on 20m 6s burst My first MS QSO on 20m - more difficult, noise 7dB stronger then 15m
HA7PL HA7PL vy short QRB 226 km on 15m 09.09.2007
IK3CHK QRB 738 km JT6M on 15m 30.08.2007 - burst at 3.6 s
YO2NAA-RXed by IK3CHK same QSO as above, 2 strong bursts at 10.7 s and at 26s
HA5LV at 11s HA5LV 3s burst at 6s QRB 252 km on 15m 04.09.2007 - strong bursts over weak tropo ?
DF2NU-1 DF2NU-2 QRB 746 km JT6M on 15m 24.08.2007 - many strong bursts over some weak ES or ES-ionoscatter
YO2NAA-RXed by-DL2RMM YO2NAA in QSO with F6GCP on 15m 28.08.2007 - one very clear burst
OE1SMC QRB 457 km JT6M on 15m 30.08.2007 - short and strong burst at 13.4s , over a lot of QRN
DL2RMM-1 DL2RMM-2 QRB 805 km JT6M on 15m 23.08.2007 04 UTC burst at 8.6s and at 11.1s on the second file
DL2RMM JT6M on 10m 23.08.2007 04:30 UTC 2s strong burst
DA0HQ on 10m CW - IARU HF championship 2007 - bursts almost every minute - QRO and a good ANT helps a lot
DA0HQ-1 DA0HQ-2 DA0HQ-3 spectran captures
DL0IGI 13 July DL0IGI 14 July 2007 Dl0IGI 16 aug 1 DL0IGI 16 aug 2 DL0IGI beacon 28.205 48W and Vertical
DL0IGI 8-Sep 1 DL0IGI 8-Sep 2 Spectrogram captures
9A2YF QRB 312 km JT6M on 10m - underdense reflections, very short because of low QRB. QSO not finished.
For any remarks and questions regarding these samples and MS on HF, don't hesitate to e-mail me.
I use to do also Meteor scatter on 2m... well, sometimes not quite usual, with only 2EL on the balcony
