With the news of that big solar flare yesterday, that motivated me for some strange reason to break out the Icom R-71a and tune around. My R-71a is getting old and has become somewhat of a basket case, but I'm finally getting around to fixing her up. She's a thorough bred having substantial mods, I think the most important being a 5.5khz Kiwa Premium Filter Module (Kiwa 455kHz Filter Modules) that improves not only the selectivity, but the ultimate rejection as well. However, I believe the caps in the PS are shot as it takes 30 mins for it to warm up and start actually receiving, then it works great for an hour, followed by heavy distortion as the VCO caps go kaput.
The VCO caps I have, so it's just a matter of sitting down and replacing them, and for the power supply, I'll try to run it on 12VDC first before I tear into that.
Initially, I was excited that we might have some great auroral conditions and I might get to hear some deep south DX, but when I heard on WWV that the K was only 3 ... pfffft. So much for that. Radio Encyclopedia from Cuba was heard faintly on 530khz, the Cuban - Radio Reloj ("Tick Tock" and morse "R R" heard) was actually pretty good on 570, but there was no sign of Mexico City on 730 or 1060. Tuning up the band, I stopped on 1610 and ON TOP OF the local travel information network, I heard Mexican music.
HUH?
Our local TIS is a system of 6 transmitters around the city, so there is no way to null them with a loop, and since that has been installed, I've never heard anything else on that frequency. So, hearing music, Mexican at that, really was a shock. It took a while, but I finally got a partial ID of something something "HH" and looking that up, it turns out to be Voces Latinas, CHHA, Toronto, Canada (CHHA-AM Radio Station Information). Kind of a let down, but any new station heard has to be a thumbs up.
So that was my excitement. Looking forward to getting the R-71a back on the air. With the 12 volts DC option, it will make for a great portable DX machine. I'm getting the itch to head back up north again for some wire stringing!
