BC-221 CALIBRATION BOOK
If I recall correctly each calibration manual was part and parcel of the
unit as they were hand calibrated and both shared the same serial number. www.fairradio.com has the mtce manual. -- 73 Hank WD5JFR wrote in message ... Hi all: Somebody knows where can be obtained the calibration book of of the BC-221? Thanks in advance REgards Heriberto LU6DBU |

BC-221 CALIBRATION BOOK
Thanks Henry and Michael.-
I found a program to make the calibration book taking only some check points. - Thanks again Heriberto LU6DBU "Michael Black" escribió en el mensaje ample.net...

Back then, the articles would all say "make sure you get a BC-221 with a calibration book", implying that it would be a terrible task to do it yourself. I have no idea whether that was the case or not, but of course, things were comparatively primitive back then. With a frequency counter, it would be really easy, just repetitive, to build up a calibration book. On the other hand, if you've got a frequency counter, you might as well just us that rather than fuss over a calibration book. Like everything else, you used to be able to buy blank calibration books at the surplus stores. Sixty years after WWII, I have no idea what kind of stock might remain. Michael VE2BVW |

in the late 40s early 50s QSTs. Pete |
