But I have managed to get a second QRP TX built, and put it in a nice little box. Pictures can be seen at: http://www.alg.demon.co.uk/radio/136/qrptx.htm#boxed The Altoids tin is not just included for size comparison purposes - it is actually part of the transmitter! Additional constructional information, including options for making the low pass filter coils, have also been added to the web page. QRM at G8RW ----------- Recent letters from G8RW describe continuing QRM problems on 136 kHz from an NTL cable television interface installed in a neighbour's house. Bob has gone to great lengths to reduce this continuous source of S9 QRM. He has set up a new antenna feed arrangement, and designed a remote tuning system to get the antenna feedpoint away from the house. But the received noise is still very strong, such that even G4CNN is only just audible above the noise. The response from NTL has been poor: they have not even sent an engineer to investigate the problem. Naturally, this level of QRM means that Bob is virtually QRT on LF. Regards to all, Steve GW4ALG
