Re: LF: RE: WSPR TX

[Chris Osborn <g3xiz@yahoo.co.uk>]

Thanks Luis,

I've never tried WSPR-15 and suspect the TX would over heat as one of the filter toroids is getting warm.

I may give it a try with reduced power another time.

I shall try Opera on another day too.

Hi LF

 

Thank you for Txing Chris

 

I'm running a 24/7 monitor on LF but WSPR-15. Have changed right now to WSPR-2 as it seems like your are using the 2 minute mode

Would be easier to copy you on WSPR-15, or Opera32

 

Actually running monitors on LF WSPR/Opera32 + MF WSPR/Opera8

Tx QRP MF WSPR+Opera8

LF,

I've just finished an LF WSPR transmitter based on G4JNT's up-converter.

I'm presently transmitting on 137.55 kHz with about 100 watts of RF into my 40 m inverted 'L' aerial, height 9 m

The quoted ERP of 0.05 W is a 'guestimate'.

I'd appreciate a few 'spots' to get a reference level for when I improve my aerial system later this year.
