Didn't Realize QRP Could Be So Fun!  Time owned: 0 to 3 months
Ordered an RS-918 look alike from Shengda Electronic Technology which they rebranded as an SD-109G but it appears to come from a common manufacturer as the RS-918. Paid $420 including shipping and trade assurance from Alibaba on August 15th and received it on August 25th and have been playing with it ever since. This model appears to have the v0.5 boards since the resistor location on v0.6 boards for R43b near the mini USB port is missing. Not a big deal as this optional resistor is used to supply +5v on that port and is not needed nor desired. After looking around the internet for mcHF Transceiver, I found lots of information (manuals, quick start up, firmware updates etc.) on the M0NCA and GITHUB websites. This model will not let you start it with the USB cable connected to a computer (gives you a white screen and wonít boot) but itís not an issue to turn on the radio and then plug the USB cable from the computer into it. It came with a recent bootloader (3.1.4) and older firmware. Updating to the most recent boot loader and firmware from the GITHUB site was easy and added RTTY with on screen decoding via a keyboard plugged into the large USB port. All features and controls are adjustable via firmware menus and, once the parameters are set, you rarely need to adjust from the menu. I like that you get FreeDV as an option. The radio connects up to Ham Radio Deluxe using the USB cable with the Mini USB connection and selecting FT-817 as the radio. Able to easily work digital modes. Played with the settings and get 10-20 watts out on full power setting (max power on 40 meters less on other bands) and 5 watts at the 5 watt setting for all bands. Hooked it up to my 40 meter full wave vertical loop and easily worked the western US from my QTH near Sacramento, CA. Audio reports were very favorable with mic gain at 15 and compression at 4. You donít need to overdrive this rig as the mic is sensitive and crisp. Touch screen is a nice feature but really donít use it and it does lack some response when selecting a feature. Compared the receiver against my Kenwood TS-590S using an A/B Coax switch. The 590, as expected, was able to pull signals out of the noise better than this rig but I probably would not be able to work those stations on 15 watts anyway.

Conclusions: The price is right, features comparable and in some cases better than my TS-590S, small, lightweight, works off a $20 4.8 AH LiPO battery for hours, fits into a small laptop bag with my Superantennas MP-1, coax, key, and wire with room to spare. This is not a plug and play, appliance operator radio but if you like to adjust, upgrade and experiment, this is one neat radio.

I never thought QRP could be so fun (previous philosophy: Life is too short for QRP) but this has changed my mind and introduced me to a fun, new facet of my ham radio experience.

It's good!  Time owned: 0 to 3 months

I bought an RS-918 (clone mcHF M0NKA) on the Recent (Quanzhou Risen Electronics Co.). The attached short instruction on one page without additional information from the Internet is insufficient for use. When checking the parameters, it was found that the enterprise was not configured, the main parameters are set by default. The transmitter power indication (Full - 5W - 2W - 1W - 0.5W) is not configured in the received device. When trying to turn on the RS-918 connected to the laptop, a white screen is displayed and the power is not turned on. This fault is described by users, but the Recent is not fixed. The primary view of the transceiver is a semi-finished product for an experienced user. Correspondence with the enterprise was limited to general recommendations from the manufacturer.
††††Verification of the declared parameters in the laboratory before adjustment. The transmitter power is 9-15 watts on different bands, the sensitivity of the receiver on the favorite range of 20 m is 0.11 μV (-126 dBm). The real reception of RS-918 signals JT65 and FT8 with the FT-450D transceiver in the same conditions (one antenna, the same versions of the WSJT program) is compared. In fact, the RS-918 accepts more stations than the FT-450D. The signal quality of the SSB transmitter is estimated by correspondents as excellent. For coordination with the antenna used a Chinese QRP tuner self-assembly. Convenient connection of the transceiver to the computer with just one USB cable! The quality of the transceiver's operation corresponds to the declared, except for the defects mentioned above.
††††Detailed instructions on the machine's settings are available at https://github.com/df8oe/UHSDR/wiki/
††††Many thanks to M0NKA! I wish to respect the radio amateurs, we are many!
I apologize for the machine translation into English!

Impressive Radio!  Time owned: 0 to 3 months
Received my RS-918ssb on Aug 10, 2017 and it worked perfectly right out of the box. Worked 5 countries in the first hour on 40m CW with 5 watts into a random wire. SSB QSOs brought excellent audio reports later the same day.

The Good: Very sensitive receiver, many DSP filter settings, peak/notch filters, noise blanker, two VFOs and split operation, built-in keyer, variable tuning rate, USB connection for computer control, SSB/CW/AM/FM/DigitalVoice, spectrum display. It has almost all the features you find on a modern SDR radio.

The less than good: No internal antenna tuner, no internal batteries, clunky menu system, no manual, no memory banks, touch screen is difficult to use, headphone volume can be too loud on audio spikes.

The good far outweighs the less than good. This is a super QRP radio. The software appears to be the same as the mcHF radio, but I have not tried to update the software via USB. Well worth the price.

Good value Fun to use  Time owned: 0 to 3 months
Just got this nice QRP rig...and so much Fun to use.. The reciver works as good as any of my Hi end radios and in a very small package..
Bought mine from China (QUANZHOU RISEN ELECTRONICS CO., LTD) and the cost was $350 plus $30 ,,shipping/tracking DHL..got it in 5 days..
The mcHF project kits have some strong following..and this is a completed unit by a radio manufacture in China..
This is one of the coolest radios I have ever had...full of features..
