That is fine :-)

What is several? On HF, several is say 4 or 5. On MF, several is 40 or 50 minutes! I often called CQ for more than one hour without any replies and i assume people can hear me.

(only a QSO with Marzio who lives abt 40 km away.
He noticed also that the band is plenty of digital modes (WSPR Opera) but apparently nobody on the air with QRSS. I explained him that due to the band characteristics when condition are good the traffic takes places in CW... but when signals are digged in the noise only digital modes are looking to give resoults.
Due to the ...birth date (hi) he regrets he can not stay up after 2200 local time (now 2000 UTC) so he's missing something but hopes when winter will approach again to hear somebody..

Hi Roger
 
I use a Wellbrook Loop type ALA1530 (MW/HF)  mounted 1m off the ground and a PA0RDT mini-whip mounted about 7m above ground.   Sometimes the loop wins other times the miniwhip.   The miniwhip is omnidirectional and uses the e field, whereas the loop is directional and uses the magnetic field.   The miniwhip is more open to BC breakthough than the loop but more sensitive.   I tend to monitor with the miniwhip, and switch to the loop after homing in on the signal if this helps.   BC breakthough is overcome using a simple series LC circuit tuned to the required band at the RX end of the coax.   The QRM at my QRT can be horrendous, as I am only 100 yards from the OH lines on the East Coast main railway line, surrounded by houses and a block of flats with associated busy roads.   My 'T' transmitting aerial 8m high is useless for RX.   I can fully recommend both miniwhip and Wellbrook Loop, both of which cover from LF to 10m.   For best results, I suppose a tuned loop about 1m square has the edge, but not as convenient.

Can anyone advise, from actual use,  how well a Wellbrook loop works on 136 and 472kHz RX ? The excellent OIP2 and OIP3 figures and directivity suggest one could be very useful.
