Milliwatting on 80m

I've been having some fun lately on 80m with my Reggie transceiver connected to my antenna through a step-attenuator.

On December 21st I answered a CQ from W2QF with an RF output power of 8mW. Henry answered with a 339 report. On our second exchange I raised my power to 50mw and W2QF lowered his power to 4w. Henry lives on the Maine coast at a distance of 304km. 

I answered K1JO's call on January 14th with 5mW. John returned with a 339 report from Northern New Hampshire (135km). We chatted for nearly a quarter of an hour with 5mW output power on this end. 

On the 20th of January I answered KC1DI/QRP without any added attenuation (84mW). David replied from Limington, Maine (173km), with a Ten Tec Triton (minus the PA stage). His 850mW signal was a very pleasant copy here with no receiver gain. In the course of our QSO I briefly dropped my output power to 2.5mW and David replied with a 239 report. He could just detect my signal at an output power of 840 microwatts although it was too weak to copy.

On the 18th of January the automated receiver at K3LR - part of the Reverse Beacon Network - logged my CQ at an output power of 4mW. K3LR is located in far-western Pennsylvania; a distance of 710km. 

My CQs were captured by both W3LPL (Maryland/639km) and again by K3LR on the 20th and 21st. On both of these evenings I was operating with an output RF power of 2.5mW!
