K4 Highlights #2: Transverter Band Displays & Dual-Transverter Receive Like the K3 before it, the K4 provides extensive support for external transverters. The K4 adds several important new wrinkles: 1. Up to 12 transverter bands Each transverter band has a corresponding button in the band

Re: [Elecraft] K4 Lore

That's true. But the KAT4 has 3 antenna jacks, any of which can also be used as an RX antenna, and the KAT4 covers a 10:1 impedance range compared to 3:1 for both the '7610 and '101. Wayne N6KR > On Jun 3, 2021, at 9:40 PM, John Nicholson wrote: > > Yes and no; both the IC-7610 and FTdx101

Re: [Elecraft] K4 “Owner’s Manual”.

Hi Sid, We do plan to merge the printed "Introduction to the K4" manual with the "Operating" manual when time permits. Until then, both are being updated. We recommend that everyone read the Introduction manual, which is fully illustrated, but use the the operating manual for detailed

[Elecraft] Elecraft K4 now in Rob Sherwood's RX performance table

Sherwood has posted his measurements of the K4D's receiver performance in his table: http://www.sherweng.com/table.html We're quite pleased with his test results, which confirm that the K4/K4D is near the top of its class (direct-sampling SDRs). A K4HD would provide somewhat higher dynamic

Re: [Elecraft] K4 postings: Main Elecraft reflector vs. Elecraft-K4 at groups.io [Clarification]
