To avoid problems during FT-8 operation I decided to use DU1/SP5APW callsign for both islands. So, DU1/SP5APW/P will not be used. According to Clublog advise (see below) I am not going to use also DU1/SP5APW-2023 callsign in Clublog. Both logs will be uploaded to DU1/SP5APW for matching purposes.

6m antenna checked

Three element Yagi, built from Buddipole set, was checked and tested today. Due to shortage of 6th telescopic whip I made a missing element from aluminium tube and screw for Massey Ferguson tractor 😀. Buddipole is made in US so all screws are inch which are unusual in Europe. Fortunately Ferguson parts are also inch and I was able to buy missing screws... The measured SWR is less than 1.5 and for the frequency of 50.3 MHz approx. 1.3.

Expedition logo

I am very glad to say that Miguel EA5ZD did me a favor and designed a nice logo for my expedition. Thanks a lot for that!

About activity

Originally this activity from Calayan Island was scheduled for spring 2020. Unfortunately, the COVID-19 pandemic prevented my plan from being implemented. So, I am coming back to this idea after 3 years.

This time the activation of OC-092 will be preceded by the activation of OC-244 from Marinduque Island. From OC-092 I will work using the callsign DU1/SP5APW and from OC-244 as DU1/SP5APW/P.

As far as I know the last activation of OC-092 took place in June 2017 (DU2/JA1PBV) and the activation of OC-244 in October 2018 (4G1L). So, I expect a lot of interest from IOTA hunters.

The equipment I will use is: ICOM 7300, Yaesu FT-857D, wire antennas and Buddipole. Operation on the 40-10m SSB and FT-8. Operation on 6m digi modes only.
