Re: A Yorek YK-901 portable to EXT ANT's!

I've modified a newly bought used, $6.00, Yorek portable with a BNC connector, to shielded RG-174 coax, to chassis GND. And??? 1st, I've tried the Windom Antenna, that I use in amateur radio TX/RX'ing. One leg is 100ft, going over a creek valley, and the other leg is 62ft, along the hillside. The center is fed by a 2kW rated 4:1 Voltage Balun. As expected, IMD and front-end overload throughout the SW bands. The only signals that I've heard fairly clearly were both CHU's, 333okHz and 7850kHz. Everything else was flooded with IMD crap. A little better on the AM BC band, with just some of my Part #15 station, AM610, coming though. FM??? Local stations, and multi-path noise. I then connected the radio to my Diamond Discone D-130J, which I use for 6M FM, 2M, MURS, 222MHz, 440MHz, and various VHF / UHF monitoring. To my surprise, SW was cleaned-up and performed well. Both the 90M and 40M CHU's came through clear. 6070kHz CFRX Toronto was clear, (At 1kW ERP.). Also heard AM HAM's well on 3880kHz. WBCQ 7490kHz and 9330kHz, both came in well. And, heard WWV at 5MHz, but not at 10MHz. Being, it was dusk here, I blame that on piss-poor propagation. I'll try this test again, when propagation above 10MHz is better. FM??? I'd gotten IMD from a couple of the big-guns here, but was able to hear some weaker stations on it. Multipath was also evident, being in this valley. However, this test gave evidence that if I wanted a simple mobile antenna to portable set-up, for super cheap SW in the vehicle, it could happen. Now, what engine and fuel injector noise will be like is a guess, but will be at least present, as in MW and CB.
