Now available for ARRL members only at: http://www2.arrl.org/members-only/prodrev/pdf/lab/ic7800.pdf KC1SX added some new 1 kHz data to the QST Product Review: BDR: 95 dB (graph on page 19) IMD: 66 dB (graph on page 20) Phase noise: -93 dBc/Hz (graph on page 21) By way of comparison, here are Orion's 1 kHz numbers: BDR: 118 dB (graph on page 19) IMD: 85 dB (graph on page 20) Phase noise: -138 dBc/Hz (graph on page 22) http://www2.arrl.org/members-only/prodrev/pdf/lab/orion_etrr.pdf And remember that the Inrad #352 kit (#762 assembled) improves IMD by "about 10 dB" (according to Sherwood) at 1 kHz over the 1000 Hz filter data listed above. So much for "astonishing, unparalleled, ultimate" and other unabashed Icom marketing hype about the 7800. 73, Bill W4ZV _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec |
