Just to mirror what Ed mentioned… I have my complete 160 - 5G station running off of my K3 bought in 2011 and upgraded. I have the internal 144 transverter which had to go back 3 times to get spurs sorted out. One think I note, is signal compression as I have pagers just below 144 Mhz and when they fire up They desense the 2 m transverter…. I’ve correlated this with an SDR. The problem is lack of filtering in the internal transverter as the front end sees well beyond 144 - 148. The solution was to add a filter with a steep rolloff below 144 Mhz…
I would hope that the guys at Elecraft when designing the new K4 transverter system will take a cue from DEMI and Q5 and ensure adequate Bandpass filtering in the front ends… I would think TOKO or similar are your friends on this … Just my 2 cents. I use the 2 m to drive all my microwave stuff as well and with GPS locking its nice to be able to know where you are … Having said that, Q5 have a really slick multi band transverter that would integrate really well on the K3 or K4… but at a price point. Anyway I do hope Elecraft come up with something that is crunch proof and rock solid for 144 222 432 MHz. 73 Dana VE3DS ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
