The Lightning Protection for Rotors If you want to buy assembled and tested board please look at K6VHF`s info here Download description of LPR New Magic QRP SWR Bridge v.3 If you want to buy KIT of Magic Bridge or assembled and tested board please look at K6VHF`s info here	If you want to use your old HF tranceiver in VHF in EME or MS QSO - you must increase stability of frequency. For example - i use my old IC745 with my 144/28 XVTR . I have good total value of frequency stability for long sending cycle without TXCO. You need only some a bit of polypropylene for VCO, 2nd LO and LO. In old tranceivers often was problem with switchknobs XIT/RIT. Good idea is - to use old switchknobs XIT/RIT for control of good relay. Now only clear of relay ladder with good contact will be control XIT/RIT . For example - i use russian relay RES-49 in easy layout !
