Narrative:
I lost communications with ZDV on 135.6. After several attempts on 2 different transmitters, myself and another crew member decided to execute lost communications procedures and started our descent from 10000 ft MSL down to 7000 ft MSL over polde (IAF) to execute the VOR runway 28 at dgw. VMC existed and this would be a practice approach. While descending through 8000 ft MSL, denver contacted us and asked our altitude. We notified them and told them we were in the process of executing lost communications procedures, however, we did not squawk 7600 during the process due to VMC. To correct this situation, I should have squawked 7600 as soon as I lost communications.
