137kHz QRSS3 test - aborted

Last night I tried some local 137kHz tests using my 137kHz beacon. Then it blew up!!  I could smell burning and the transmission stopped. 

This means I cannot do my test unless I can repair my beacon. Also, to be so badly damaged it suggests the match is poor and the heatsink inadequate. 

I think this puts an end to my tests at 137kHz.

UPDATE 0929z:  In a vain hope, as my FT817ND was widebanded when I bought it, I tried directly TXing on MF and LF. It said "TX err", so no luck!
