The stamped serial is what was received from the company that built them. The first 2 digits is the series (run) number and is usually the same as the stamped # which also went on the manual and warranty card.

Earlier products had a different way of doing things and a lot was done all in house.

I guess the larger question I really have is why do you hate the ARRL? 

A better question would be why you equate skepticism and criticism with hate.

When an organization (of which I am a member) claims to represent it's members yet doesn't seek or seem to care about receiving input or comment from those members, I can't help but question the sincerity of their representation claim. That isn't "hate"

When that organization doesn't even care to establish a means of receiving input, I question their sincerity. Observing that isn't hate!

When they don't respond to their members, I question.....

Any reasonable person would question their sincerity. If you actually think my opinion is unjustified, that fine but it seems the majority of hams who are not members and not eager to join may agree. If I were you, I'd be more concerned with fixing that than judging my perspective.

To be blunt, you aren't qualified to judge other people, their motives or their opinions.

OK, great! so you are NOT a hater. And you are a member too.  So what were you gonna ask him?

I was aware of the 1978 Ham Radio article, but not the 1996 "K1TTT Technical Reference" document that refers to the HR article. The difference is that K1TTT specified 12/th-wave transformers at each end of the transmission line; i.e. the transmitter and the antenna feed point. That assumes that the antenna feedpoint is 50 ohms, which is probably the case in the original poster's 20m beam, but not necessarily for a simple dipole feedpoint near 70 ohms. From the "K1TTT Technical Reference:

The K1TTT article was written by Fred, K1VR, who is now the ARRL NE Division Director. All are good ole MA and NH boys who were/still are YCCC members as I was.

The coax is not limited to just 50 and 75 Ohms.

Worked this a.m. at 1051z on 40m ssb. Again they were surprisingly very very weak, like the other morning.

Don't forget 10 meters. From my QTH it's open most days around 1400 local time.

This article points to the idea that CW might best be learned by changing up what the learner does.

Activity was good in the Pre-Stew. In spite of problems with the balloon vertical grounded to the Pacific ocean I made 41 QSOs. Stew scoring is based on distance and with everything far from Hawaii each contact is worth 10 or more points.

The dominant areas seem to be NA and JA. It would help if they actually turned their beams more often to  areas with difficult propagation.  Their beams seem to be locked on TE paths which makes it difficult for other areas of the world to work them on the higher bands.  I could hear VK's calling them on 17 and 20 meters  with their beam pointed towards Europe and NA. Its hardly fair if your signal gets attenuated 10db to 20 db  as well as fighting dominant easy propagation paths. We see this time and time again with  the African expeditions locked on Europe or NA while ignoring or not turning their beams  to other areas of the world.

Still nothing heard on the bands needed here, 15, 12 and 10 m.

Low Bands have been smashing in here.
