HT1000 Transmit Power alignment Question

I was wondering if a HT1000 VHF radio is programmed from the factory to be set at 5 watts High power and do they do a transmit power alignment before it leaves manufacturing?

I just want to make sure that the 2 radio's that I have are set to 5 watts of power. When I go into the program (Transmit power alignment) and the settings are for the test 154.225 and the settings states Softpot Value is (27 for the high) and (47 for the low) does this sound right?

Is the only way to get an accurate reading from the radio is to place it on a watt meter with a 50 Ohm dummy load? Thanks

Troy has a valid question here.

I am going to answer it as best for him and others. The values in the soft pot alignment screens in the RSS are steps of adjustment and are NOT related to the accual power output in watts. The lower number the lower power, but they are just calibration steps in the radio.

You really need the correct adaptor for the antenna port, a wattmeter, and a good 50 ohm RF load. You also should be able to also monitor the current drawn by the radio in transmit.

Not always true. Sometimes the values realtes to the amount of attenuation. Thus, the higher the number, the lower the outcome whether it's power, deviation, comp settings.... (Astro series radios specificly.)

Long story short: Get a service monitor, and a copy of the basic service manual.

In the case of the HT1000 Will is correct the lower the numbers the lower the power. AND you must exit the service mode to get a correct reading of the output power. When turning mine down to 2 watts for MURS I had 2 watts indicated on the meter. Fortunatly I decided to double check afterwards and found the power to be 3 watts after leaving the service mode and disconnecting the RIB. After a little trial and error the readings were 1.9 watts (better safe than sorry) when done.

To answer the OP's first question, Every HT1000 that I have gotten from the factory was set at 5 watts for VHF and 4 on UHF unless you specifed otherwise on the order sheet.
