When I ordered a KPA500, I also ordered the capacitor and crystal kit to do the wide band SSB mod on my K2. I plan to do the mod tomorrow (13th Dec) and will let you know how I feel it worked out, both from the point of view of the mod itself and audibly.
My K2 has already had the 2nd filter "flattening response" mod done, which makes some difference. Having listened to a number of K2s transmitting on SSB (mostly on the UK Elecraft Net), those with the original bandwidth sound poor and the wider ones sound good... So hopefully mine will improve. I will record a chunk of the band around my K2's transmission on my Perseus SDR which will show both the transmitted envelope and allow me to listen to it afterwards. I will then compare the transmission with the modified version. If you like, I can arrange a sked with the K2 and you will probably hear the difference yourself. 73 Dave, G4AON K1 no. 1154, K2 no. 1892, K3 no. 80, KPA500 no. 573 ------------------------------------- I am not happy with the original 2.2khz ssb filter in my K2 (serial 1926). It sounds very restricted and fine tuning the BFO setting is quite critical and tx audio ends up either too bassy or too toppy. I'm thinking of fitting the wider ssb filter mod kit . That's the replacement xtals and changed caps. Has anyone done this ? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
