It’s always a pain finding the manuals for test equipment. You might use it for a little while then you don’t need it for 6 months. The perfect solution is to put it where you can always find it quickly. Hmmmm.

FG085 miniDDS Function Generator

This generator is almost entirely based on the kit that is sold all over on EBay. The manufacturer, JYE Tech, and Spark Fun seem to be the only source of information including schematics.

Icom IC-7300 HF/VHF Transceiver

This image has an empty alt attribute; its file name is IC-7300-FrontPanel.jpg

HF and 50 MHz RF Direct Sampling 100 Watt Transceiver with Touchscreen. An amazing radio with a sensitive receiver range from 30kHz to 75MHz.

Kenwood TM-V71A 144/440 MHz Transceiver

This image has an empty alt attribute; its file name is TM-V71A-e1587929455612.png

Mobile 50W dual band transceiver. Can set both receivers to same or different band since they are independent. Wide reception from 118-524MHz and 800-1300MHz – excluding cellular blocked frequencies. Has EchoLink capability – as if I had time for one more thing. The model is Type K.

NanoVNA-F Vector Network Analyzer

  • Manufactured by KKmoon – one of the many enhancements/clones of an open source project using the Si5351 for a VNA up to 300 MHz or so.
  • GitHub source (displayed on startup screen – but it lies) and documentation at /github.com/flyoob/NanoVNA-F
  • VNA/SWR/Smith chart/Group Delay display
  • Bandwidth: 50 – 1000 MHz
  • 4.3 Inch IPS TFT Digital Display Touch Screen
  • MF/HF/VHF Antenna Analyzer
  • Standard aluminium housing to protect SMAhead and reduce the interference of external electromagnetic wave to instrument. The RF front end is designed with a metal shield that allows the S21 to have a dynamic range better than 60dB over the full frequency range.
  • The NanoVNA-F measurement range is 50k-1GHz. Use the harmonic of the clock chip SI5351 to measure frequency up to 1000MHz. At 600M-1GHz, the S11 has a dynamic range of 40dB (the standing wave ratio is less than 1.02)
  • Switch to a large capacity 5000mAh/3.7V lithium battery, longer standby time, and expand a USB interface. Usually, it can be used as a power bank when the instrument is not used.
  • The LiPo charging IC to be changed to IP5306 (with 2A high charging current), making the charging time shorter. Upgrade the user program by virtual U disk (16MB SPI flash memory inside).
  • NanoVNASaver (PC software to control/view NanoVNA)
  • NanoVNA-F Quick Start Guide
  • Related manual (translated from Japanese)
  • Early device block diagram and schematic
  • NanoVNA is able to be controlled via USB serial interface from Python
