Learned about the MIDCARs and the ECARs nets from a Facebook group and tuned in this morning. I was encouraged to go ahead and check in, so no need to just listen in until I feel I've learned enough about them. I heard a call for any stations to check in and I got real excited, grabbed my mic, keyed up and got that TX-Error again. I downloaded the Japanese band plan (because this radio came from Japan - see previous posts) and learned that I will not be able to transmit on frequencies above 7.200Mhz on 40 meters. It's all good, I'll just have to save up and try and get a comparable radio with similar capabilities. Meanwhile, I'll just listen in to these great nets.
I bought this Yaesu FT-897 as a gift to myself for passing the General Class exam last month. I was going to buy an antenna but decided to make one myself to learn more about them, so I made a field expedient, 1/4 wave end-fed. I had gooten into amateur radio with my dad who became a silent key nearly three years ago. After hearing the radio crackle to life with the sounds of a 40 meter net I forgot about how I wouldn't be able to use it on all amateur bands (because it's a Japanese model), and I wanted to run and tell my dad all about it. I wanted to throw my call out but I figured I'd better just listen for now. I was as excited as a boy on Christmas.
I crimped thr coupler over the main element and the contact of the SO-239 connector before using some heat shrink for a bit of added structural support. I'm not like all the other high class and fanciful hams, so I used my daughter's hair dryer on high heat to shrink the heat shrink. It worked like a charm!
All parts printed and assembled to check for accuracy. Again, there's no license required for this one. Stay tuned!
Had to meet a client the other day and when we were done talking about work he asked me if I like my mobile radio. The next 50 minutes went pretty fast, talking about antennas.
Everything packed in but still getting too much pressure against the reset button, so that will need elevated before I can tighten the housing down
Began a little project. No amateur radio license required for this one. Whatever could it be? Hint: 900mhz
Frames completed after 17.5 hours.
