assistant: th
I wouldn't be so sure on that.  The 40 meter dipole is three half
wavelengths long on 15 meters.  It will have gain over a single half
wave, in some directions.  Of course there are nulls in between the
peaks so in other directions it will work less well.  The key to making
this work, by the way, is to cut the 40 meter antenna for the low end of
the band.  Otherwise, the 15 meter response will be too high.

Write your reply.

assistant: In general, the W suffix on a tube meant ruggedized for military
operation.  Electrically they are about the same although in many cases
can stand more abuse.  Use the Ws as if they were anything else.
Incidentally, the 6146 tube is basically the same as the 807 and the
6L6 and many other types.  There are minor differences in configuration
and plate dissipation ratings.  Those with plate caps are good to higher
frequencies than the single ended types.  Some have low loss bases, and
so on.

  Henning-
     I understand that the 6146B has a little higher plate dissipation than
the older tubes.  The 6146W is a ruggedized version of either the 6146 or
6146A.  It should work well in your TS-520.  The 6146B may work better, but
I'm not sure they were available when the TS-520 came out!
     In a repeater application, the most common problem I've had with the
6146 and 6146A tubes, has been a loose connection of the plate cap.  It seems
that high operating temperature causes the solder to oxidize.  Eventually a
small "circle" forms around the wire in the center of the cap, and the tube
appears to be bad.  Re-flowing the solder will fix it temporarily, but it is
only a matter of time until it happens again.  (This may not be a serious
problem on SSB.)
     The plate cap of the 6146W and 6146B tubes I've seen, were welded
instead of soldered.  In that respect, they are definitely superior to the
ones that are soldered.

  Mark-
     I would agree if he was talking only about tone burst or DTMF.  However,
CTCSS (PL) tones must be injected AFTER the audio limiter.  If they are fed
to the input of the microphone amplifier, the tone will be notched-out when
voice peaks go into limiting, resulting in a drop-out at the repeater
receiver.
     I've used CTCSS encoder circuits from Communications Specialists.  I see
that Amateur Electronics Supply's latest catalog has them, as well as some
from a company called Norcomm Tone Signalling.
     Be sure to keep your wires short and away from strong RF.  It might be a
good idea to shield the output lead.  I ran the ground and output leads as a
short twisted-pair, isolated from the FM modulator by a 100K Ohm resistor.
CTCSS tone deviation should be between 0.5 and 1.0 KHz, so I aim for 0.75
z.
     Most of the ones I've used had a DIP-Switch to select the tone.  One
extremely tiny version required solder jumpers to select the tone.  It can be
a nuisance to re-adjust the tone after the rig has been buttoned up!  You may
find a way to access the DIP-Switch from the outside of the rig, but be
careful about picking up RF in the wires.

  Ivy-
     I wish Wayne was here to tackle this one.  As I recall from my Antennas
class almost 30 years ago, current is what causes radiation.  Signal strength
at a distance from a wire antenna, is related to the integral (summation) of
the differential current flowing in the wire, taking distance and angle
(relative phase) into consideration.
     Approximately two thirds of the radiation comes from the central third
of a dipole.  An end-loaded dipole shortened as much as two thirds, may be
within a couple dBs of a half-wave dipole.  The "Inverted Vee" dipole is
based on the idea that it is best to have the high current portion of the
antenna (center) higher than the low current portion (ends), if you can't
have the whole antenna high.

assistant: Thanks Fred, this is exactly what I was wondering about too, if he
might have been thinking of DTMF tones. The current mic has just a few
buttons on it for channel up-down (I think) and the like, about 5 of them in
the middle of the 'front' area of the mic. I was skeptical of PL injection
from this point, but not knowing how ICOM might have wired the thing (and
being unfamiliar with the
-really- technical details of injection) I figured I should ask about it.
        At a recent ham swap, I found out that the radio was probably built
in the mid-to-late 70's, and was one of Icom's first attempts at an all-mode
mobile... Not one of their best attempts to date, but quite serviceable. It
is not likely that I will need much more than FM and CW for some years yet,
but you never know and the price is certainly attactive. In fact, another HAM
emailed that if I didn't end up with it, -he- wanted it... :-)

user: You are replying to Ivy Iverson about "6146s".

Write your reply.

assistant: You aren't really wrong in your comments about the tubes, although
there are some inaccuracies.  The dissipation rating of the 6L6 was 19
Watts I think, and the 6L6GC went up to more, perhaps 30 Watts.  The 807
had a five pin base and a plate cap but internally was pretty much the
same tube.  The plate cap enabled better separation of grid and plate
circuits, and thus operation to slightly higher frequencies.
There was a whole bunch of audio tubes in the 60s that were variations
on the 6L6, such as the 5881 and some other numbers that escape me.
Meanwhile there were variations on the 807, such as the 6146.  But
internally the differences were minor.  The intended use dictated the
physical arrangement but the electrodes were the same, a beam power
pentode with 19-35 Watts of dissipation.  The different ratings came
about from different ways of removing the heat, and perhaps minor
differences in materials.
So, for low frequency use, any of the tubes pretty much were electrically
interchangeable.  You may remember the 829B, which was a pair of them
in one envelope, with a glass base and two plate caps.  I used one for
years in a transmitter.  The 2E26 was smaller, perhaps more like a 6V6
in ratings, but with a plate cap.  The 832 was a pair of them in one
envelope similar to the 829B.
