This is a great HF receiving loop antenna. I'm using it with an RSPlay SDR and I'm shocked at how well it works. I have it hanging in a closet next to my home computer and run SDR Console v3 and it's much better than my old six foot dipole in the same closet. It is seriously comparable to my attic dipole connected to a Ham radio transceiver. I'm pulling in a bunch of Ham operators on 40, 80 and 160 meters using Lower Side Band. Short wave AM reception is also very good. Give it a try. 73 de K9OJ

This thing works well and is very comfortable to wear. I liked it so much I bought one for my wife too. I sleep with it so I can track my sleep quality. I have the hourly measuring turned on so it measures and logs my heart rate, blood pressure, fatigue and blood oxygen levels every hour. It also lets me know when my android phone rings. My wife uses hers with an iPhone and she loves it. I have accidentally showered while wearing this a couple of times but the unit is still running strong. It will run almost a week between charges and that's with the hourly monitoring turned on. Be sure and install the Wearfit2.0 app and not Wearfit 2.0 (note the space between the t and 2) Overall I'm very happy with the H5 Smart Watch.

This thing is freaking powerful. I run the laser at 10% power most of the time for typical engraving in wood and plastic. It really can cut wood at 100% of 20 watts. Setup was easy and the software is pretty easy to use. It can even be run by an Android phone using Bluetooth. I'm using USB for my desktop computer. Here's a hint for the software, right-click the "Control" tab edit window and select "Text" to type text and "Load Image" to input a picture.

It works on GPS, cell phones and 2.4GHz WiFi but it does not affect 5GHz WiFi. I confirmed the function by viewing the specified frequency slots for GPS, cell, Lo Jack and WiFi using an SDR receiver. The N8 Anti Tracker does not transmit in the 5GHz WiFi band. My Verizon LTE phone dropped a conversation as soon as the N8 was turned on. The 173MHz Lo Jack frequency was only slightly affected by turning on the #2 switch. Lo Jack was not affected by any of the other switches. In the manual, "BD" stands for BeiDou, the Chinese GPS system. The switch numbers and antenna numbers coincide. Flipping the 8 DIP switches on determine what is transmitted. Switch and Antenna # 1. 3G PHS ? (I could not determine what frequency was transmitted) 2. CDMA 800: 851-894MHz 2. GSM 900: 925-960MHz 2. LO JACK: 173MHz (weak signal) 3. DCS 1800: 1805-1880MHz 4. WiFi 2.4G/4G: 2400-2500MHz (does not affect 5GHz WiFi) 5. BeiDou Chinese GPS/LTE800: 791-821MHz 6. GPS: 1570-1580MHz 7. 3G1 WCDMA: 2110-2170MHz 8. 4G1 LTE2600: 2620-2690MHz I received the European style 240v converter instead of the US 120v needed but I had a spare 12v 2amp +center adapter so it was no problem. You might want to send them a note to remind them to send the correct adapter. The 12v DC in jack on the N8 is off center but the plug works and charges the unit. Overall I am impressed with the N8 Anti Tracker.

This HackRF One works great and it comes with a .5 PPM TXCO. I updated the firmware to the latest with no problem. I added a Banggood PortaPack H1 and case and the combo is very cool.

This PortaPack H1 works great. I paired it with a Banggood HackRF One and the combo is very cool. I updated the PortaPack firmware to the latest release with no problem. The "HackRF mode" works just like a normal HackRF One so you don't lose anything by pairing your HackRF with a PortaPack. This unit does not come with the case so purchase that separately.
