Weather Band: 162.400, 162.425, 162.450, 162.475, 162.500, 162.525, 162.550. These are the 7 NOAA broadcast frequencies used in the USA.

Expanded setting is to accommodate MARS/CAP frequencies; you must be careful not to transmit illegally out-of-band. To expand (or unexpand), hold down 2 and 3 and turn the radio on. Once it powers up, release 2 and 3 keys. This information is included in the Owner's Manual for all but the first product run. In the first production run, the information was packed separately from the manual in Addendum 190-1106 04A00.

You can override the default offset for each memory.

To change the default offset, follow the steps in "Understanding the Configuration Menu." to display the oS menu item, and rotate TUNE to change the offset. The transceiver lets you set the offset to be in the range from 0 MHz to 4 MHz in steps as set by the frequency step option.

UNDERSTANDING THE CONFIGURATION MENU

Your transceiver has a configuration menu that lets you modify operation settings. Each of the following sections explain how and when to use each configuration menu and select options.

1. Press VFO.
2. Hold F for at least 1 second. FUNC flashes.
3. Press T-SQL. The HTX-242 displays rC and the currently set receive tone.
4. Rotate TUNE, or press UP or DOWN on the microphone, to set a different receive tone. If you do not want a receive tone, select oFF.
5. Press UP ARROW. The HTX-242 displays tC and the currently set transmit tone.
6. Rotate TUNE, or press UP or DOWN on the microphone, to set a different transmit tone. If you do not want a transmit tone, select oFF.
7. Press T-SQL or PTT to save the settings.

To activating Subaudible Tone Transmit and Squelch:

1. Press T-SQL once. T appears. The HTX-242 includes the selected transmit tone with your transmissions.
2. Press T-SQL again. T-SQL appears. The HTX-242 includes the selected transmit tone with your transmissions and requires the selected receive tone to open squelch.
3. Press T-SQL a third time to turn off both subaudible tone transmit and squelch. Neither T nor T-SQL appears on the display.

The Microphone Plug for the HTX-252 (Cat. No. 190-1127) is a round plug with pins 1-7 arranged around the edge in a semi-circle, with pin 8 in the middle. With the empty space below pin 8 on the bottom, the pins are numbered clockwise from the bottom left, 1 through 7.

The pinouts are as follows:

Pin	Function	Plug Pinouts
1	Microphone Audio / PTT
2	Scan / Pri
3	Down / Up
4	5 Volts
5	Lock / Shift
6	Call / Step
7	GND
8	F / MHz

WARNING: This procedure clears all stored information.

1. Turn off the HTX-404.
2. Press and hold down F + CLR.
3. Then turn on the HTX-404.

1. MARS operates primarily in the HF portion of the spectrum, rather than VHF or UHF. While there is some MARS activity in the VHF portion, we do not offer a frequency modification.

2. CAP operates on the VHF band, on adjacent frequencies of the Amateur 2 Meter Band.

3. CAP does not operate on any UHF frequencies that are adjacent to the 440 MHz Amateur Band frequencies

This is why our 440 radios do not have frequency modification features, like some of our 2 meter radios do.

• MARS: Military Affiliate Radio System - HF Operations
• CAP: Civil Air Patrol - Air Search and Rescue.......a U.S. Air Force Auxiliary

• 151.820 MHz
• 151.880 MHz
• 151.940 MHz
• 154.570 MHz
• 154.600 MHz

Our 190-1206 and 190-1210 (mobile version) radios can easily be programmed for four of those frequencies.

1. Turn VOLUME fully counterclockwise (transceiver OFF).
2. Remove the battery door, but do not remove the battery (battery must have some charge).
3. Choose a preset frequency from the chart below and set the encoder DIP switches to match the desired frequency.
4. Turn the radio on and the new frequency is set.
5. To set the second frequency in the 190-1210, flip the frequency switch and repeat steps 1-4 above.

DIP Switches

D = down or OFF; U = up or ON

For the 190-1217:

Selecting A Business Band Frequency:

1. While holding PUSH TO TALK, turn on the transceiver. You hear "frequency" and the current frequency setting ("frequency nine," for example).
2. Choose a business band frequency from the following table:

   Frequency	You Hear:
   151.625 MHz	One
   151.955 MHz	Two
   154.570 MHz	Three [MURS channel (blue dot)]
   154.600 MHz	Four [MURS channel (green dot)]
   151.700 MHz	Five
   151.760 MHz	Six
   151.820 MHz	Seven [MURS channel (no dot)]
   151.880 MHz	Eight [MURS channel (no dot)]
   151.940 MHz	Nine [MURS channel (no dot)]

3. Repeatedly press PUSH TO TALK to scroll through the transceiver's business band frequencies. When you hear the business band frequency you have a license to use, release PUSH TO TALK.
4. Press MONITOR twice to store the frequency.

The 4 switches in the radio are to set 1 of the 8 possible transmit frequencies. There is no information in the manual because this is not a user-selectable function. Our stores can set the frequency; you will need to bring in your FCC information regarding frequency allocation.
