Default Lost Shakespeare Art-2 VHF radio tester instructions.

I've lost the instructions for my Shakespeare Art-2 VHF radio tester. I have the tester and the 36" piece of cable, but I can't seem to find the instructions. Online searches have proven futile. Can't find them on the Shakespeare site either.

Help please.

Thanks in advance for any help.

isn't like a inline watt meter, reads output? switch and read reflected? I leave the one I have in all the time reading output power.

OK I looked at a picture of the thing. Here is how I would think it works.

The top switch has three settings. Watts, Set, and VSWR. When set to "watts" it should read forward power. If the forward power is less than 25 watts on high power you have a problem. The radio is on its way out. Chances are you will either have the full 25 watts or a lot less.

But really forward power is not the important test. VSWR is. Before you can test for this you need to set the top switch to "set". Once on "set" key the radio, and use the knob till the needle is in the blue range of the meter. I would set it so the needle just touches the blue range on the meter. Unkey the microphone.

Now set the switch to "VSWR" and key up again. You are now reading VSWR or "voltage standing wave ratio". It is a ratio of forward to reflected power. You want your SWR to be less than 2. If it reads over 2, something is not exactly right. If the SWR reads in the red - stop. Something is VERY wrong. Cut off the antenna connector and strip back some insulation. Is the shield (outer braid) or the center conductor corroded? If so keep cutting back, looking for good wire. Once you find good wire, put on another connector and try again. Re-set the meter and read VSWR again. If it is still bad (above 2) then replace the antenna.

ALWAYS DO THE FIRST SWR TEST ON LOW POWER. If it reads ok on low power, reset the meter and then try on high power. If the SWR is OK at low power and bad at high power - replace the antenna.

When I do a SWR reading on my system (every month or two) I check SWR on channel 1 and 88A. This way I am checking the SWR over the entire range of VHF frequencies. If SWR is good on channel 1 and 88, then you are OK. If you want to check SWR on 16 do it quickly. Remember, low power first then high power if everything is OK on low power.

Every time you change power level or channels, you have to re-set the meter.

The bottom switch turns the meter off (pwr off), turns the meter on (bat) and generates a tone on channel 72 (rx test). If you want to use the tone generator, you can. But if the antenna transmits then it will also receive.

By the way, all antennas reflect some power. This reflected power is directed back to the radio. The rest of the power is turned into radio waves in the antenna, or lost to the resistance of the antenna cable as heat. High SWR means a lot of power is being reflected. This is bad because you want as much power as possible to be turned into radio waves.

Inside your radio there is a transistor called a "final". It is the final thing that generates a radio signal, and sends this signal directly into the cable / antenna system. If this transistor gets too much reflected power it blows. Once this happens the radio is dead. It is not worth repairing unless you have a very expensive radio OR it is under warranty. This is why it is important to test SWR from time to time. Things can go bad fast, and you will have no way of knowing your antenna system has something wrong until your finals blow and everyone says "captain you are breaking up, say again" when you are only 50 yards away. You will always receive fine, unless something REALLY REALLY wrong goes bad.

Sorry I didn't come back to this thread sooner. I had to go out of town shortly after posting my question and I didn't have computer access for several days. Thanks for the help guys.
