Hi LF
 
Thank you all ! This band is amaz= ing :-)
 
Great dynamic reports Markus= . You are now my ODX at 1500 Km !
 
>>Eeehm, and what did you run last night? = Don't tell me it was just the nacked U3 with, what, 100 mW TX power?

Well, I know it is HARD TO BELIEVE= , but that's it. Absolutely. U3 (old, not S) using an ICL7667, not the BS17= 0's which would provide more power
In fact, i'm only using half the = ICL7667 powered at 5V. This is good enought to driver the MF PA and do not = cause thermal drift in the DDS
 
Antenna height is the key. The 80= m building tower is part of the antenna, so it works as a top coil&nbs= p;feeded, top capacitive loaded 90m vertical antenna
The radiation angle must be also = quite low, which is another interesting factor. Now I'm completely sure I bought the right house&nb= sp;for a Ham point of view ! ;-)
 
Let's keep the system running a f= ew more days. Still working in daylight in Opera32. There is time to test o= ther modes too
 
Then the next issue (appart of PA= ) will be a switching system to be able to alternate Tx periods in MF and L= F. Think it will be doable using small power
and vacuum relays. It's a pity to= be forced to choose to Tx in only one band

Hi Luis,

My congrats again!

Will keep it running during daylight also
