 Letter to captain of the vessel at sea
@@ Line 182: / Line 182: @@
 The captain is responsible for any transmissions made from the vessel, so you need to convince them that you're not going to do anything that would reflect badly on them - hence I would go for a very upfront description like that

+SOTA is fairly simple arrangement. Best way to do it first time is to go with someone who's done it before. Find hill that you can climb with your ability level. Create SOTA account at https://www.sotadata.org.uk/en/. Find out if you need VHF or HF radio. You cannot use repeaters so you need direct contact. Most people seem to use VHF and have HF backup. Make sure you are safe. Weather is good and you are prepared for climb. Figure out how are you going to log contacts, paper, mobile. Charge batteries. Don't forget microphone (ask me how I know). Make a list of things you do not want to forget. Think what antenna you are going to use.
+On the day: Make sure you are safe  Take radios up the hill. Make sure general public is safe with your antenna system. Call: CQ SOTA CQ SOTA, CQ Summits on the air. Wait. Make contacts. Spot yourself on the App or ask others to spot you on the app. Get ready for a pileup. Deal with the pileup. Descend. Log activation on https://www.sotadata.org.uk/en/. Profit :D

+So to complete the experiment. We were trying with @Ben - EI9IUB - IO63fj to run 9k6 IL2P at 12kHz ( @Ben - EI9IUB - IO63fj hope it was 12.5kHz ) and we had some success. 30W over 40km (with a hill in the way) with 11.7dB gain and 15m or so heliax coax. Sometimes it just worked and sometimes it was really bad. All in all marginal. DEV was nearly all the way up on NinoTNC. TXDELAY was in 3rd quarter. We were using Motorola GM360 with SQL on.
+Very happy to see you.
+GB7RDG is at 7052.75 kHz (7051.25 USB dial for NinoTNC), mode is QPSK600 IL2P+CRC.
+NET/ROM enabled, please keep nodes broadcasts short, i.e. MINQUAL set high
+GB7IOW is in its usual spot.
