Greetings from John, AF3K!

Check your callsign in the AF3K logbookherefor our recent QSO!

100% of contacts are QSL'ed via LoTW - usually at the end of each operating session. I am also very happy to confirm viapaper QSL (direct or via bureau).

QRV Turks & Caicos March 24-29, 2017!

Operated from the island of Providenciales in the Turks & Caicos March 24 - 29, 2017. Ross, W2TT and I, accompanied by our XYL's, operatedspecial contest call VP5P for the CQWW WPX SSB Contest. Over 2,500 QSO's - Thank you!!. At other times we operated as VP5/AF3K and VP5/W2TT. Station: Flex 6500, Flex Maestro, Elecraft KPA500, 3 element SteppIR 130 ft. above sea level.

Currently thestation in Naples, Florida includes a Flex-6500, a Flex Maestro, and end-fed dipoles on 80m, 40m, 30m, 20m, 17m, 15m, 12m and 10m. Really like operating CW using theBegali Mono key which drives the Winkeyer in the Flex. Alternatively use an exernal Logikey K-5 keyer. Logging via N3FJP Amateur Contact Log.

The latest additionto the Naples shack is an Elecraft KPA-500. Here is a quick video made right after construction.

I periodically operate marine mobile on "Nellie D", a 37' Lord Nelson Victory Tug that I own with my brother Dave (N7PO). Rig onboard is an Icom IC-7000 to a Morad 23' vertical. Current location updated via 2M APRS using a Kenwood D710. Also a member of the Waterway Radio & Cruising Club. We have cruised Nellie D. on the West coast from Seattle to Vancouver Island to Ketchikan Alaska. On the East coast we have cruised mainly between the Chesapeake Bay, Florida and the Abacos and Exuma islands in the Bahamas. Look for us in the summer of 2017 in the Great Lakes.

I like using the Flex because it performs very well, and it lets me do things that I just can't do with my other radios. For example I don't need external boxes to get great audio.

The Flex SmartSDR software supportsmultiple microphone profiles that are independendently kept from other transmit parameters such as mode &power. Each microphone profile contains my settings for things like transmit bandwidth, the speech processor settings, and the audio equalizer settings. For each of my microphones, Ihave one profileoptimized forragchewing and others for DXing.

It's nice to have control over all of these transmit audio settings, but how do you know what they sound like without recruiting a very patient on-air helper? Below is a very cool video by NM9P showing use of the Flex 6500 full-duplex capability for making microphone profiles by listening (and recording)your own transmitted audio! (Ken provides more examples on his YouTube channel.)

To keep the receiver from overloading, the output power is kept to a few milliwatts by transmitting via the transverter port. The received audio is heardin a separate receiving slice on the same radio! The end result is you audiois much closer to what someone hears over the air than if recorded fromthe mic input.
