Delivery of converter box was reliable (On time and in good condition). Apparently, it did not work so I contacted seller. They responded quickly and carried and sorted out the issue without fuss (refund).

I wish I had found this tuner sooner! I tried other products that are targeted to help people like me setup/aim an antenna, and this works better by a wide margin.Learned about this item from Tyler the AntennaMan (YouTube). I live in a area with less than great OTA coverage and aiming antennas correctly is critical to obtain acceptable TV reception. The tuner in this unit is more sensitive than my 4 tuner Tivo DVR or my TVs (Samsung and Panasonic). So I use this inexpensive tuner as part of my tool kit for antenna setup and tweaking. It is small, light and has a signal strength meter. I can duct tape the tuner to a small PC monitor and take it up into the attic so I can freely move around the attic to find the best spot and direction to aim the antenna.The unit is inexpensive, and the build quality reflects this fact. The remote is functional, but I would not want to use it everyday, the buttons are too close and feel too flimsy. I don't plan on using this remote for any length of time. If you are planning to use this TV tuner on a daily basis, I would investigate using a different remote.

I have been using the Mediasonic HW130STB for about 5 weeks. Here are my observations so far.The device runs hot & it conducts a lot of heat to the USB stick I have plugged into it. There are vent openings on the bottom and sides but not on the top. I have it propped on edge with the USB port toward the bottom to help keep it cool. I hope it doesn't cook my USB stick.The device is very light and it it difficult to get it to lay flat with a 75 ohm antenna cable and an HDMI cable attached. I will probably stick it to a vertical surface with double-face tape to resolve both issues.The manual that comes with the device has VERY small print & is hard to read. I downloaded the user manual PDF for the Mediasonic HW-150PVR. The case layout is different but all of the user functions appear to be identical & it is a lot easier to read on a computer screen.The PVR programming functions are accessed through the Electronic Program Guide. I didn't find it intuitive, but it worked well once I read the manual.The HDMI output aspect ratio and resolution (1080 to 720, 480, etc.) can be changed via the menus (I have not tried the CATV or composite outputs). However, the PVR function ONLY records 1080p in the MTS format, and the files occupy about 8GB per hour of recording. Correction: The PVR records at the resolution of the incoming signal (720x480 for a 480i channel).The manual states that USB flash drives and HDDs can be formatted either FAT32 or NTFS. FAT32 has a file size limitation of 4GB, so recorded programs will be split into multiple 30 minute files. NTFS does not have this limitation, so the entire program will record in one file.I have been using Shotcut to convert the MTS files into the more versatile MP4 or MKV format, edit out ads & cut down the file sizes. I also used it to stitch together the 30 minute video files before I formatted the USB stick to NTFS.Update: One other nice feature is the device turns itself back on after a power outage.

My new Mediasonic Homeworx replaced an older version of ATSC box that I bought directly from Shenzen on eBay several years ago. I really liked the old box until the flash memory stopped working. When new, the old box would let me create up to about nine DVR schedules. Then after about three years it went to zero. All the functions of the old box are still good, except for the DVR schedule. I am still using a second old version ATSC box where the DVR schedule capacity has gone from about 14 entries to four. I replaced the ATSC box with zero DVR schedule with a new Shenzen model. I expected it to be like the one it replaced. Instead the DVR schedule has an eleven day week and zero working flash memory to hold schedules. I am really hoping that the new Mediasonic will have better quality flash memory. Ask me in three years how the flash memory is holding up. Right now it looks very good.I have been using old model USB 1 Western Digital disk drives for DVR storage. They worked great on the old model ATSC box and work just as well on the new Mediasonic box. I assume that the new box will support USB 2, but have not tried it. The old boxes do not support USB 2. The old model Western Digital units arrived formatted as fat32. To use them for DVR storage I had to reformat them to NTFS. I suspect the reason thumb drives do not work is that they are formatted as fat32. I bet that after reformatting to NTFS, they would work. I noticed that the Mediasonic has a disk format feature in the menu. I did not need to use this, the USB 1 Western Digital drives transferred to the new box without a hitch.I had two boxes because I had two outdoor antenna. I’ve been experimenting. The first antenna has stopped working. I suspect it is because it is now pointing to the sky rather toward the horizon. I have it clamped to a plumbing vent that is now bent over after the last wind storm. I wanted two working ATSC boxes, one to watch while the other records or record different channels at the same time. I tried using the RF output on one box to the second box. That works, but there is significant signal attenuation especially when the first box in the series is working. I installed a Channel Master signal-splitter amplifier. Now both boxes get the same signal strength. I have two antenna on the roof on the same mount with a Wineguard signal combiner feeding a Channel Master antenna preamp. That feeds into the signal-splitter amplifier inside the house. All this gets me about 40-60 over the air channels depending on atmospheric conditions. The antenna mount once held a Direct TV satellite antenna.I’m thinking of another type of antenna to try. I might replace the antenna on the bent plumbing vent with something on a tower next to the house. We will see how much ambition I have.Some things to note. The Mediasonic menus are identical to the old ATSC box. The remote controllers have the same functions, but they are arranged very differently. With the two old model ATSC boxes, when I clicked the controller on/off button, one box would turn on and the other would turn off. That, I found, was a useful feature. I now have two separate controllers. I suspect, if I get another Mediasonic that this feature would return. I set my Mediasonic to the 24 hour clock. Please remember that it does not automatically switch between standard and day light time. I seem to get caught twice each year. The DVR scheduler assumes that a digit placed in one of the two hour slots means that a zero should be in the other. Why? The old model didn’t do this. I like that the Mediasonic DVR scheduler starts with the working channel. The old model did not do this.The old ATSC box DVR scheduler has an annoying bug. When more than two shows are scheduled to record where each starts on the same hour that the previous show ended, there is about a 20-30 second additional delay that adds up. This delay pushes the start time and end time forward by that amount. This means that after several iterations the start and stop times are out of sync with the shows being recorded. This is a real issue when recording one of those marathons where 10+ episodes are broadcast back to back. Making the stop time a minute earlier than the next start time seems to help. Except when the scheduler is turning on the unit before starting to record, then it turns off on the ending minute and back on at the starting minute. Fortunately there tends to be a lot of advertising between each iteration to absorb the slop in the time. I haven’t used the Mediasonic enough yet to check this on the new model. I noticed that the Mediasonic initial boot goes a lot faster than the old ATSC boxes. Otherwise there is no difference. -- It is now official: The bug described above is present in the Mediasonic.Here is instructions to reformat a thumb or disk drive to NTFS:Put the following in a Windows Shortcut Target: %windir%system32cmd.exeStart in: %HOMEDRIVE%%HOMEPATH%Use the following commands in the Microsoft Command PromptType "DiskPart" in the command prompt.Type "List Disk” (make note of the disk number of the target USB drive).Type "Select Disk X”, where X is the target USB drive noted above.Type "Clean”.Type "Create Partition Primary”.Type "format FS=NTFS”.Type "Active”.Type "Assign".Type "list volume".Type "Exit"Be real careful with this. As soon as you type “clean” the target disk is wiped clean. If you want to get rid of a disk drive and hide your data, use the above procedure. I suspect a well-equipped forensic lab can still get at your data, but not easily.The format can take a long time. A 1TB disk drive can take 8+ hours to format. Like those Western Digital disks noted above.

I tried this out since the Youtuber Antenna Man uses and recommends it, and he has solid antenna related content, and has helped me many choices with many Amazon purchases for my OTA set up. He apparently uses it to test all the Antennas he reviewsI don't know how a professional Antenna installer like himself would use it, especially when reviewing products in conjunction with it.It loses channel signal if it drops below what the tuner deems as 40% strength, yet both my tvs will still hold the exact same signal as long as it stays over 20% signal strength (a newer non 4k Insignia, and a older Emerson).I tested it both without this box connected, and with the cable going in and coming out the other end of this box with the RF out.With the box powered off, I picked up the channels signals pretty much the same. So it's not as if the box itself is causing a significant loss of signal, the tuner is just so crappy that it losses a signal that both my TV's built-in tuners will pick up just fine.Avoid using this tuner.
