That's something I've been doing, swapping over to WF100, been doing it bit by bit.
CPC always seems to be the cheapest for me when I've bought WF100, Webro used to have an outlet on eBay I bought my cables from but they haven't put anything on there for ages! Was a cheap source at one point.

I've got far too many boxes in the cupboard! But not quite as extensive as that.

Have you noticed any signal degradation with the A/B switches?
None at all after extensive tests so long as you use decent cable & F connections.

I use a couple of those, too.

Very high quality, and you can even train a SWMBO to use one: "If the screen is blank when you select Rai Uno, just push that button"

The Bay of Fleas gives several hits.

Nelson, which frequencies were "off" on the feedhorn on the 1.8? Did it vary with LNB or receiver? Will test this on mine... Using an Inverto White C120 here with decent results.
Hi - C.J.
Its at least a couple of years back now maybe three .. since i gave up using the c.m. feed on that dish .. so i don,t recall the frequencies .. there were two or three that were discovered at the time .
i remember swapping lnb,s and feeds around a lot .. and never got a sensible reason as to why it was. until these were noticed i had always been quite happy with Inverto white and/or black C120,s on that dish.
I did document it on here at the time .. i will see if i can find the thread later.

Hi - C.J.
Cant find the thread where i talked about this issue .. But i,m remembering that one of the affected frequencies could have been - 12.284 V 2200 - Cherifla tv - at 31.5 west .. not sure if was using the same parameters then that it is now though ? .... ( it currently comes in at 5.5 - 7.0db depending on weather and time of day) i could barely get a signal back then let alone a lock ... on the 1.8 with C120 and c.m. feed .. and yes - i tried a few C120 l.n.b,s into different receivers .. but the only thing that dealt with it was removal of the c.m. feed and replacement with a standard 40mm l.n.b. no problem after that ? ....there were other frequencies that were suspect, but its too long ago now to recall them ...
What d.b level do you currently get from Cherifla tv on your 1.8 c.m setup ? .... being much further south you may well do much better than me ... According to footprint maps this channel should not be seen outside West Africa .. l.o.l. :eek:

regards :)

Hm, I get about 8dB on 12284V, which sounds low from what I remember (though it's very dark cloudy right now) and I get virtually nothing from 12335V. I don't have another motorised dish to check.

Edit: BTW, I seem to have an odd issue with my F15, where certain frequencies don't really come in that well. This is nothing to with DECT or cabling, since the Mutant gets them OK. I haven't investigated enough to check what exact frequency ranges this affects... I have another F15 in the loft, so need to try that as well. Perhaps it doesn't like the LNB I am using (Inverto White C120).

No but you have plenty of dishes, can you ask the wife to stand outside very still? :-rofl2

Hi-
8 d.b. sounds good for that channel to me :)... 12335V. is the same for me just a flicker of signal that,s all.
I,v had l.n.b / receiver compatibility issues in the past with Inverto C120,s and an old Technomate DAPCI

Regards ....

I'm currently getting 7.7db on 12283 V, SR2200 (Cherifla) on 31.5W using a 1.5m dish with an Invacom C120 quad LNB. The dish might be partilly blocked by a large conifer but not by a great deal if any?

Used to get BT SNG feeds at this slot many years ago, along with regional BBC feeds, it was quite busy...
