NAVTEX Pad

This program is not stand alone. A navtex radio signal must be broadcast from a separate radio then the program listens and decodes it.

Clunky and not reliable. Does not work as advertised in my experience and I’m dissatisfied

Downloaded this as it says it also decodes RTTY. When you open the app, even with ZERO audio input, the very cartoonish 1980s spectrum display dances like it’s on fire. (Not even close to accurate.) This program decodes garbage with ZERO signal being injected/received. The SETTINGS are extremely rudimentary, and the FAQ is a joke. I have not tried the other stuff, nor NAVTEX functions, but I wish I had read the other reviews before I wasted $8 on this package. Don’t make my mistake.

Fails to copy even small fragments of 45b/170Hz rtty correctly under pristine (lab) conditions.

Would be worth more money to Black Cat if they gave it away for free and charged for a user manual. A total POC! Do not buy this!

Used this app along with their HF fax program. Neither were able to decode. Not worth the money.

The least they could do is deliver it configured for US Navtext stations which are like most of the world, or with instructions for same, but no. The instructions just list the settings with barely enough detail that someone knowledgable about the technicalities of Navtext could figure the rest out. Does it work? Yeah, sort of, if you ever figure out the settings and are having a good day on the radio. But if you’re serious about receiving Navtext broadcasts, which means you’re offshore 200 miles or more, you wouldn’t want to be depending on this app for your weather. So far I’ve managed to receive about 50% of a Navtext broadcast and the novelty has worn off.

Great tool for DXing! My first night with this app, I logged 5 different NAVTEX signals on the east coast!! Directions on Black Cat's website may be a little easier to understand than the ones contained in the app. Also the app records broadcasts as text files - just remember to select "create a new file" and to clear what youve already received from the main screen for each instance otherwise it all ends up in one text file. BRILLIANT!!

Works perfectly. I am using a communications receiver on a longwire and it decodes weak signals easily.

I am using a Grundig G3 radio at 517 khz ussb, the program settings at 930 center frequency and invert audio signal on and it decodes Navtex perfectly. I just set it near my radio speaker. Even with a local thunderstorm the day I was wrinting this, the program decode the Navtex transmission.
