JI1FGX/DU9 Mindanao Diary144MHz Repeater Production Study(2009/11/09)
Today I visited DU8UTP Franco's house in Iligan, about 60Km away!
This is Lanao, the most active guerrilla area in northern Mindanao. But since the view has been like this for so long, I don't quite understand what on earth they are guerrilla activities for! We have heard that sometimes they destroy roads, bridges, commercial buildings in neighboring Iligan, etc. travel route If we don't use the ferry, we'll have to make a big turn to the left.
Driving along Iligan Bay would mean a detour of about 200 km, so we took a small ferry from the port of Osamis, a 20-minute boat ride
By the way, haven't you seen this boat? Japanese-language information is written everywhere in the cabins. No Smoking", "Toilet", "Emergency Exit", etc. I think they probably brought a ship that was retired in Japan, I imagine that it was used in large lakes such as Lake Biwa and inland seas because of its size and the fact that it is a ferry with a two-way gate.
This is Mr. Franco's shack. Recently purchased FT-1000MPMARKV (100W) sitting in front of the shack He is also quite fond of things, or rather, he is crazy about amateur radio! We had visited the home of DH1NGP in Germany before and this time with Mr. Franco, and as we share the same hobby, we had a lot of fun talking about the common topics. We shared the same problems and the fun time flew by!
Now, here's today's main topic, 144MHz repeater equipment. It was actually in operation a long time ago, but the controller broke down and it was left unattended. The controllers were made at a local ham store, and when I looked at them, all the IC model numbers had been scraped off! Timer ICNE555, LM386, etc. are expected to be lined up based on function and parts arrangement
They are using the KENWOOD TR-7950 radio as is. This radio is also very worn out, so it's doubtful it will really work.
But this is DU8UTP Franco's handmade duplexa. I felt his enthusiasm was genuine. But I heard one of them got married somewhere. It would be easier to link the transmitter and receiver at different frequencies in a remote location.
They say it's a condenser made of copper pipe. Adjustment screws were out on top.
This is the blueprint they had drawn by an expert. I asked about the loss and other details, but ended up with "I'll look for documentation".
