Chris G3XIZ has just sent me an updated list of his beacon reports and 2-way QSOs with his 15mW FETer transceiver. His best 2-way DX is now over 450kms and he has worked 3 countries already. Remember this is ordinary speed CW, not QRSS and sub-hertz digital signal processing stuff. Chris has "good ears" and is a very good operator. A lot of his success is down to his skills.
He told me, "The little TX is doing far better than I had ever imagined and as a result I must now re-appraise my perception of QRP operations - Hi !"
