I have the yaesu 101 twins, FR101s receiver and FL101 transmitter. Transmitter uses the stock 6JS6C tubes. The 6HF5 tubes can be made to use in it, with slight change on tube sockets (look up specs). These tubes can be gotten from 15 to 20 bucks, much cheaper than the stock tubes and have almost the same output. My FL101 was made to be able to use these tubes or the stock ones. I just purchased another pair of the 6HF5's at a hamfest locally for 15 bucks each, good old GE stock, and work great. I wanted to have some spares because we all see tubes are getting scarce. Hope this helps.

    March 23, 2023 @ 14:45 UTC (UPDATED)
    Not the best of timing for aurora sky watchers across northern Europe and North America, however a moderate (G2) geomagnetic storm is currently in progress. A watch for Strong (G3) conditions has been added. The Bz component of the interplanetary magnetic field (IMF) has been tipped south, a condition known to fuel geomagnetic activity around the polar zones. Stay tuned for the latest updates.

ALERT: Geomagnetic K-index of 7 Threshold Reached: 2023 Mar 23 1446 UT Synoptic Period: 1200-1500 UT Active Warning: Yes NOAA Scale: G3 - Strong
