What you have is a Lissajous pattern generator. It can be used to compare
the frquency ratios of two signals by counting the number of "loops" horiz
vs vertical. This I think is used to calibrate rtty setups, giving the
classic 'eye' pattern. You could also use a similar setup to trace
transistor gain curves. (horiz = base voltage, vert = collector voltage).
If you want another neat idea, connect small speakers up and tape tiny
mirrors on the cones, one speaker mounted vertical, the other horiz. Shoot
a laser off both mirrors and onto a wall. A free laser show!! Watch out
for laser safety, for your eye's sake!!!
I sometimes monitor my ham RF output to check for clipping, modulation, etc.
'Scopes are _very_ useful!!!

Subject: HTX-202 caveat
Until recently I thought I was the only one to encounter a weak-link in
the '202 but have since talked to three others who had the same experience.
To wit: In removing or replacing the battery case it is very easy to
crack the thing ridge of plastic on the lower front panel. At first
appearance this looks like a bit of trim to cover the metal guide rails
for the battery....wrong! This holds the entire battery pack in position
to prevent lateral movement. Once cracked the battery case "wobbles" and
DC voltage contact is intermitent. A call to Tandy resulted in a price
qoute of >>$78.00<< for a new case! At present a very strong, very wide
rubber band is holding the trim in place until I decide what cement I
want to use on it. Mine broke as I was sliding the pack off....others
have said theirs broke sliding it on. It appears any slight misalignment
puts pressure on this extremely this strip of plastic...then zap.

or something similar. I've tried tech support hotline and so far

Subject: Kenwood TM-742
Ted,
I have been using a Kenwood 742 since about the time it was first released.
Nothing but good performance in my shack. Easily programmed and the circuitry
is readily accessed. My set-up utilizes the raw audio (pre-discriminator)
output feeding a PrivatePatch V. This gives me a cross-band repeater,
autopatch, CW identifier, and switchable input frequencies. The unit is remote
controllable with DTMF codes and provides the ability to change freqs, CTCSS
on/off, power level, VFO/MEM/CALL, etc. Only flaw is the "ability" of the
radio to pick up ambient DTMF signals in the shack which can then change the
operating parameters if one is not paying attention. This only occurs when the
speaker mike is the selected mode vs the PrivatePatch. The option of a third
band is another nice feature. All in all, I am very happy with the purchase
and user-friendliness of the radio. Drop me a line if you would like some
specific info................. ...............................................

Can someone point me in the right direction:
on how to convert a Motorola Mocom 70 to
2 meters. I have a complete radio but
no manual or documentation of any kind.
The radio is currently on 152mhz, or
something close. Any assistance would be
appreciated. tnx, beavis (beavis@io.com)

Sorry, not possible. The HTX-202 is designed to NOT receive outside the
2m band, thus rejecting all that crap from pagers and other nearby
radio services.
If you want to receive extended range VHF, you'll need a different
radio or a scanner.

I sent two out to a guy in new jersey who had the software to program
them to the ham band. This guy uses syntor x conventional on the ham
band.
One of our spectra was trunking only, the other
had only one conventional channel. Only conventional channels can be
programmed to the ham band. Then the VCO needs to be adjusted to lock
up. And of course the rx front end & pa need to go thru the works too.
An immense pain.
I found the company in san diego call RF Neulink (also RF industries)
which is known for rf connectors/adapters. They have new transmitters &
receivers for vhf/uhf/900mhz. they are crystal controlled. They have
another model for 900mhz which is synthesized.

Icom IC-735, with an AH-2 antenna tuner. Look around it is a simple 2
diode mod to make it "transmit out of band". Plan on having it taken
away from you if you insist on using it instead of a type accepted
marine band radio. Hang out on rec.radio.swap look at the local swap
meets. Keep an eye on the consignment shelf in your ham stores.
It is a simple yet very effective piece of equipment from Icom that does
exactly what it is supposed to do. Work well.

Hmmm . I've been using an IC-CM8 pack on my 202 for about 2 years now,
but never had this problem. I did have to open up the battery pack and
remove the ball detent, as the RS packs just have a dentent on the
radio side.
