Reviews Summary for Hamtronics model RWX NOAA Weather Receiver
Hamtronics model RWX NOAA Weather Receiver Reviews: 1 Average rating: 4.0/5 MSRP: $149.00
Description: Our model RWX is a very sensitive and selective commercial grade receiver to monitor critical broadcasts from NOAA/NWS or Environment Canada. You can depend on it for demanding applications for reliability and superior reception.

Excellent 0.15Áv sensitivity provides good reception even at distances of 70 miles or more with suitable antenna. No comparison with ordinary consumer radios or scanners!

Essential for airports, marinas, police, fire, and highway departments, rescue crews, CAP, RACES, SKYWARN, Coast Guard Aux., amateur repeaters, broadcast stations, state and local emergency managers, hospitals, nursing homes, schools - anyone needing a professional quality emergency warning receiver.

Automatic mode provides storm watch, keeping quiet normally, but alerting you by unmuting receiver and providing an output to trip remote equipment when the weather station broadcasts an alert tone. This could be an audible alarm device or something like the alarm circuit on our REP-200 Repeater. The hearing or visually impaired can use the RWX to trip strobe lights, pagers, bed shakers, PC's, etc. Storm Watch LED indicates that receiver is actively monitoring for warnings.

Listen mode allows you to manually unmute the receiver anytime to get up to date on weather conditions and then reset the automatic alerting circuit when done.

The RWX Receiver is small enough for emergency or portable use, and it can be modified to operate from a small 9-12V battery if needed. The receiver uses crystal control for accuracy, and all 7 channels are provided, including the new split channels. An internal switch allows you to select whichever channel you receive best from your location.

Channels supplied: 162.400, 162.425, 162.450,162.475, 162.500, 162.525, 162.550. Crystal controlled,
selected by internal DIP switch.

Solid Performer  Time owned: more than 12 months
I've had my RWX for about 3 years now and it continues to perform perfectly. I keep it on 24 x 7. The NOAA stations are selectable by a DIP switch internal to the unit, so it's not made for switching NOAA stations easily - it's really a commercial grade product. It also receives Cananda's equivalent to NOAA - Environment Canada.

The unit receives very well with a short antenna at the BNC input jack on the rear panel.

It DOES NOT have NOAA's SAME decoding function used by lots of other consumer receivers. This feature lets you program your weather receiver to unmute when NOAA issues a subaudible alert for your specific county - the codes used to program your receiver are on NOAA's website listed by state and county.

The unit unmutes every week when NOAA sends out it test tone. If your not home when that happens, you'll return to hear the RWX unmuted and playing away - not a problem for me, but I'd rather have the SAME decoding feature.

The only other gripe is the power cube that comes with the unit does not have a grommet at the entrance to the back panel - it seems for $149 we could afford a grommet where the +12 Vdc enters the case.

The speaker is mounted facing up in the top cover, so there's plenty of audio. Also there is an LED on the front panel which lets you know the unit is on, but muted. When unmuted, the LED is off, but of course you've got audio from the RWX. It also has a volume control, which provides plenty of audio.

In general I have no complaints - it does what it is supposed to do and is 100% reliable.

Looking at the circuit board inside, you can tell this is commercial stuff, and not a consumer product.

If I had it to do over, I'd probably find a similar quality product that included the SAME decoder included with the receiver, given the price I paid.

I called Hamtronics and they told me that this unit is used nationwide by TV news rooms since it's a "set it and forget it" type device.
