Hello all, Today I finally had time to finish the K3 low frequency mod, adding the caps and removing the inductors from the band pass board.All went well, this is an easy mod even for an old ham.With my calibrated ear and S meter it is noticeable that the noise is lowerat the low end of the band (100 khz ).The NDB were also stronger, From central Oklahoma in the daytime I amable to hear stations in TX,OK,KS,AR,NE some as far as 500 miles.Antenna is a 60 ft 630M top and base loaded vertical.The K3 is working very nice on the 630M experimental band.I have been TX/RX on this band for almost two years with experimental license WG2XXM. Most of the time running around 5 watts ERP.The 475 khz 1mw signal coming from the K3 is going into a HB Class D PWR AMP.Running WSPR and JT9 most of the time.I have been off the air for a while doing another hobby with my Son ( Astrophotography ).Weather permitting I will be txing WSPR tonight.Set your radio to 474.2 upper side band WSPR software.You will see my trace at + 1520 -- that will be 710 on the waterfall.Thanks agn Elecraft.73 Ken K5DNL/WG2XXM ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
