I have a Clas Ohlson Weather station bought Dec 2012
Reciever WH1080
Transmitter WH7
The transmitter stopped working and I thought a quick battery replacement would do it - but now have a permanent red light and no connection.
As Clas Ohlson dont sell the transmitter any more Would either of the 2 transmiters sold by Maplin work? and if so which one?
Many thanks

Re: Faulty transmitter
The Clas Ohlson devices are 868 MHz and Maplin 433 MHz as far as I know, so they will not be compatible.

Re: Faulty transmitter
Hi,
Yes, agreed, the CO stations use 868 MHz and AFAIK the Maplin's always 434 MHz.
Also, the manufacturer (Fine Offset) changed the Wireless Protocol (data format), I believe with the CO's since 2012 (Maplin's changed earlier). However, these stations are sold under numerous other "badges" so you might find an alternative supplier:
The best starting point might be Walters and Stanton but they are rather more expensive than Maplin. They seem to have several possible replacements; I think the 868 in the model numbers is the radio frequency so a "Watson" 8681 transmitter might be suitable. As a "specilaist" supplier they may be able to help you, I suspect that you need a "mark I" version, but do make sure that you can return anything that isn't suitable.
Note there are at least four types of transmitter, even excluding the different radio frequency and protocol versions: One of the two Maplin's is for a station with no wind Vane (or USB interface), so is certainly usuitable for any station compatible with Cumulus. Some transmitters (e.g. the other from Maplin) don't support the Radio Controlled Clock, so that part can't work (but the Console can still be set manually). You probably have (an early version of) the "third" type, whilst the fourth supports solar measurements, which surprisingly are "(backwards) compatible", but only with the "later" protocol (which I don't believe your station uses).
Cheers, Alan.

Re: Faulty transmitter
Thank you for your replies
As I felt I have nothing to loose I have been waving my soldering iron at it - somehow managed to get it going but a little erratic - i guess there is a dry joint or the pcb has a fine crack.
I will persevere!

Re: Faulty transmitter
Did you make it work?
I am in the same situation. Red LED is all the time on except half second.

Re: Faulty transmitter
Had the same problem with mine.
Resoldered more or less all solder joints om the transmitter board.
It seems to wotk still after a few month.
Connectors to wind an rain oxidize and if it happens you can try to exchange connector on thoose cables.
They sre standard 4 pole multi.
