D66D Comoros
Satellite image of Comoros Is
Comoros is off the coast of Mozambique
One call on my 6700/ALS 1300 and my dipole. I was surprised my dipole was slightly better than my vertical. He was peaking -97 dBm, good solid signal but the band was a little unstable

ZP/ZP1P Albania
The True DXing Group is on from Albania
Worked them tonight on 40M while sipping some coffee: nice sigs, good ops, laid back pileup

TO5FP Saint Pierre & Miquelon
Here is one I didn't know about, TO5FP Saint Pierre & Miquelon (FP). It is an archipelago of 8 French islands off the coast of Canada. They have a nice write up on QRZ.com
Big S9 signal, up 1, on 40M. Good ops working everybody. They are working 80-10

Antena interactions Flex 6700
There was a question on a forum about whether an antenna connected to antenna port 2 would somehow blow out the ADC while transmitting on antenna port 1. The 2 antennas in question were physically close to each other but transmission on one was strong but reception was weak on that antenna and vis. versa
I set up the following experiment.
Pan A (top) connected to RX1 and TX1 antenna port
Pan B (bottom) connected to RX2 and TX2 antenna port
port 1 connected to 1/2 wave end fed 40M vertical over 4kft of wire
port 2 connected to W5GI variant of G5RV at 50ft
Antennas separated by about 175ft
I used DDUTIL to readout S-Meter data on pan A & B, as well as transmitter power from my LP-100A watt meter

Here is a video demonstrating my results. The conclusion is my radio with this setup is 100% safe. When in half duplex mode the ADC is isolated from the RX antenna, and in full duplex mode I was able to measure the signal on my ADC and it was well below any danger from my transmitter.
Also it's great to have a radio from which I can get accurate data and determine precisely if there is any danger without just guessing.
