David G0MRF Thanks for guiding us into your endeavour and hopefully you've a good demonstration at the AUK event !
BTW Your ADF4351 LO-settings are ok , I presume ?

@G0MRF as addition to G0MJW 's input, the lens (with glue) is ' clicked' over a ledge / ridge, so with some wrenching it can be pulled off .. sometimes a screw driver may help ... ; -)
DG8ABG I referred to a 740 MHz SAW filter, not a 2.4 GHz one ... (?)
The 740 MHz filter is handy when you go down in two steps from 10489.5 to 432.5 MHz:
10489.5 - 9750 (LNB LO) = 739.5 [SAW-FILTER] - 307 MHz (2nd LO) = 432.5 MHz
Shortest reply I read here on the forum. Congrats George! : -)
DH2VA Yes! That was the occurence I mentioned, you were the one who published it : -)
DB2OS That already exists. People making 'QSO's' via the internet (no, I am not talking about Echolink ; -) because they can't install an antenna or experience too much QRM.
ON4CJQ that one counts as 9M2 and not as 9M6 (unfortunately ... )
G0MJW Please ask Attilla if he wants to fire up the equipment again?
PY2RN I think your map is a little pessimistic. E.g. Paramaribo (which is left of your line) is in the footprint, well in ... it's 'on' 0.2 degr ; -)
S57NML Where did you get that map from ? Do you have the full Monty?
There is one city (on the border) in Paraguay that has also around 1 degr or so.
AFIK LU is not within the footprint of QO-100 ?!
Therefore my question . . .
PY2RN Who did you work from Argentina over QO-100 ?
That 9M62 event station where Sion operated counts as 9M2
OK .. the missing one was 4U indeed.
Never heard him. . .
I don't have the precise stats here, but from memory:
Grids worked: 305
DXCC worked: 76
PY2RN: I miss(ed) ZA, 3A, A4 .. but the other one?
I use this 740 MHz filter in my transverter. It's only 3 x 3 mm ; -)
I remember we had one earlier this year and noticed a minor increase in (background) noise level
Edit: that was with a 60cm dish
Should I think about bringing a backup?
As long as Murphy's Law exists, that isn't a bad idea ; -)
G8UGD It is not necessary to have a 'full Monty / super duper' converter with a NF < 1 cB (centi Bell ; -). A LO and one diode is enough to monitor the 2.4 GHz signal.
G8UGD I have. I have two actually: a 2400 - 144 MHz AO-40 converter and a 13cm (2320 MHz) transverter where I mix the RX IF-signal down to 144 MHz with a 80 MHz 'crystal block' and a diode.
I reckon when the 3IMD products are somewhat more than 30 dB down it's fine because the dynamic range of the NB tpx is also around 30 dB (provided you're not using to much uplink power and stay below LEILA ; -)
SV1BDS B.t.w. I received the CETC CTI OSC5A2B02 10 MHz OCXO today. Will take a little time to test it because I have too much projects to finish (like doubling the shelf surface with MDF in my shoe cabinet ; -)
