Century 21 bulb miss read
That incandescent bulb is an 1982 NOT an 1872. Guess I need to get my
eyeball nuts tightened. WA9VLK |

Man, I'm trying to type this darned posting in too much of a hurry...
OK...breath... the bulb is an 1892, NOT a "1982" NOR an "1872". Sheesh. Anyway...TAKE THE DARNED BULB OUT OF THE METER and see if your drift diminishes. WA9VLK |

Update
After 8 hours of "cooking without the meter bulb" the receiver has drifted less than 100 cycles (50-80 cycles nominally) , far better stability than before. To preclude any heating from the finals during long transmit periods I am going to experiment with moving the finals to the outside of the year of the case. I'll post my results here for anyone who is interested. WA9VLK I believe I'll continue to drift the same amount as before. ;-) vy 73, Bryan WA7PRC |
