Versatile DC-DC converter, works from 4 volt to (at least, what I tried) 20 volt. Output is clean DC voltage from low to high; adjustable. One technical minus point: the output can peak up to 45 volt, unwanted, when input voltage is lower than 4 volt. Minus point for this individual case: I had to pay "inklaringskosten" because the EU customs say that Banggood did not pay that. Despite their promise. I think Banggood will solve this problem.

Q: How do I set an offset of for example 10.7 MHz in a receiver to display not the oscillator frequency but the actual receiving frequency? Do I need a pic programmer for that or can it be done without changing the program?

This is a real receiver with the Russian software! Software version 1.0C is an improvement over the more standard demosoftware! Low interference from internal electronics is also a positive point. One negative point is the low sensitivity of the touchscreen and some misalignment in the touchscreen positions. Over-all: good receiver.

In the product description missing: "Is the program present in the delivered hardware?". Answer: yes, the tuner works out of the box, after the diy soldering etcetera. One very important remark: the connection between tuner board and display unit is with four wires (plus, minus, clock and data). ----> The clock and data wires need a cross-connection in the wires (the sequence of the wire connections on the board is different on the display unit). I had to look for this, because the display was not working initially.

Good amplifier, clear sound. High efficiency. Use this with a 19 volt laptop supply with max current of 3.5 ampere and output power of two times 25 watt is easily possible thanks to the high efficiency. Remarkable low radio interference on medium wave and other AM frequencies! Stays cold/cool with higher output. Good choice also for Li-Ion (4 cells in series) and portable use. Frequency range 19 Hz to 25 kHz zero dB when loaded with resistor. Some deviation of frequency response with complex load, up to max plus and minus 2 dB in the 10 to 16 kHz range with some speakers. Happy with the small size too. Recommended.

Brightnoise Just for your information: the delivered firmware for my tuner was version 3.0 (up to date) and works as explained in the manual by N7DDC.

Incredible good product. Also selective measurements can be done (fieldstrength). Helpfull in finding interference sources. I am very happy with this spectrum analyser. Accuracy without calibration is already within a few dB. Actual lowest frequency in my spectrum analyser is 25 kHz!

Easy to use and accurate. Resolution 0.1 degrees celsius. Narrow measurement bundle to measure temperature at ceiling: very usable for leakage of heath in a house.

Well performing. One outside temperature transmitter can be received on two of these units, in different rooms. That was important for me. Display is clear and easy to read.

Q: Missing in the specifications is the input impedance on the connector: resistance and capacitance. For table-top oscilloscopes this is standard 1 Mega Ohm and 100 pF in parallel. With ten-times attenuating probe the input impedance CAN be 10 Mega Ohm inparallel with 10 pF, requiring a special probe. Please add the input properties to the specification.

Today I received the spectrum analyser for 2.4 GHz. Incredible small. The analyser works, but can't be used as a sniffer. I am very disappointed in the sensitivity: I have not seen more than a few millimeters line lengts. My router is 300 mW and even close to the antenna(s) there is only a small output on the display. In 3 meters distance there is NO display frequency occupation visible . Appearance is good but display is mounted under an angle and glued; can't be corrected. It is a spectrum analyser: what a pity that the sensitivity is so poor that it can't be used as sniffer.

Accurate and sensitive device! According specification. Power supply voltage is not critical (no offset from Vcc-variation!). Really accurate measurement device! Can also be used as receiver: connect antenna to input and audio amp to output: audio from strongest AM-signal is audible; LOG-conversion works as automatic gain control. With antenna tuner (for selectivity) it is a nice monitor receiver. I am very happy with this power meter.

Brightnoise Google Translate: "Do you strengthen the mobile phone network because the network connection I have thin (?)" What are you asking exactly? This equipment has no network or mobile phone connection. There is a USB-connection with a computer.

Usable solder wire, but flux is smellling different from usual and tin wire is not as good as top brands. Good price performance, but not for all applications.
