[ARC5] T-17 on eBay crying in my beer

[J Mcvey via ARC5]

What can you do with the transmitters below 160 meters? The FCC hasn't blessed anything except 1 W into a *VERY* short antenna on 2200 meters and "grovel status" applications on 600 meters. 
I just bought  a 600 meter R-23 to monitor the experimental stations, but that's about all we can do at the moment.
When the time comes, a T-15 could be de-tuned a bit lower for this band.
Are any of you guys running 600 meter experimental stations? If so, how long did it take for approval? What was involved in getting it?

Well, to be somewhat more precise, those extremes apply only to the T-16 
and T-17 (*not* the T-15), and depend on the specific antenna 
characteristics.  The TN-6 was necessary *only* when you had to feed a 
short fixed antenna with a capacitance above 60pF, so its usefulness is 
pretty limited.  The 20w CW power applies only to the T-16 and T-17 
feeding a training wire antenna *without* the TN-6 (which isn't needed 
under those conditions anyway.)  The T-15 was apparently never intended 
to feed anything other than a trailing wire.  The manual is admittedly a 
little hard to read - you have to look at both
 Figure 8-56 and paragraph 
4-38 to get the full context. Theoretically you could get 20 watts CW 
out of the T-15 as well into a long enough trailing wire, bit it's not 
explicitly stated - just implied, I guess.

Yup.  The same L-52 coil was used in the T-16 through T-18/ARC-5 - which 
is a good thing, as I have been able to resurrect a couple of T-16s with 
L-52 coils from far more numerous T-18 parts hulks.
