Hello, Taken from, the http://www.df9ic.de/tech/trxtest/trxtest.html
"The Elecraft K2 also has a low IF design using conventional VCOs which should result in a good LO noise supression but does not. You may compare the ARRL test results of the LO noise that Elecraft publishes on their own website and which is closely within our blocking test result (our measured -95 dB RX blocking in 20 kHz offset is equivalent to -129 dBc/Hz LO noise). The high level of TX noise shows that there seem to be design flaws choosing too low signal levels internally. The AGC threshold is ridiculously high (subjective impression). I also do not understand why it uses low quality ladder crystal filters instead of a filter from monolithic duals like any other radio does. Overall it was the worst HF radio in the test (OK, a 144 MHz IC910H is still worse...)." Is the K2 + XV144 really bad combo or the others transverters are much better? 73' SM7VZX _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
