Deep Dive Into The RigExpert AA-2000 ZOOM Antenna Analyzer, SWR/TDR/Cable Loss And MORE

9 hours 56 min ago

Here is the Rigexpert AA-2000 Zoom, their flagship antenna analyzer. This is SO MUCH MORE than checking SWR. This is a complete analysis in your hand. Check antennas for resonance and see every aspect of the antenna and system. Using the TDR feature, you can map out your feedline and check for shorts or faults within your coax or antenna. Measure cable length, calculate velocity factor and see the loss of your length of coax at different frequencies.

RigExpert AA-2000

The RigExpert AA-2000 is a powerful antenna analyzer designed for testing, checking, tuning or repairing antennas and antenna feedlines.

Graphical SWR (Standing Wave Ratio) and impedance, as well as Smith/polar chart displays are key features of these analyzers which significantly reduce the time required to adjust an antenna.

Easy-to use measurement modes, as well as additional features such as connection to a personal computer make RigExpert AA-600, AA-1000 and AA-1400 attractive for professionals and hobbyists.

The following tasks are easily accomplished by using these analyzers:

  • Rapid check-out of an antenna
  • Tuning an antenna to resonance
  • Antenna SWR and impedance measurement and comparison before and after specific event (rain, hurricane, etc.)
  • Making coaxial lines or measuring their parameters
  • Cable testing and fault location
  • Measuring capacitance or inductance of reactive loads

Senator Blumenthal Supports Amateur Radio at Senate Confirmation Hearing

Mon, 12/06/2021 - 4:53am

Senator Richard Blumenthal (CT) received an affirmative reply from FCC Chairwoman Jessica Rosenworcel when he asked her to commit to providing his office “an update on the steps that the FCC is taking to support amateur radio operators.” The Senator posed the written question as part of Rosenworcel’s renomination hearing conducted by the Senate Commerce, Science, and Transportation Committee.

Blumenthal took note specifically that “Radio amateurs voluntarily provide an array of public services, especially emergency and disaster-related support communications when infrastructure has been destroyed by a hurricane or similar disaster. Their contributions in this area are regularly recognized by local and state authorities.”

“ARRL is grateful to Senator Blumenthal for his support and recognition of radio amateurs,” said ARRL President Rick Roderick, K5UR. Blumenthal has previously co-sponsored legislation supporting amateur radio, and his staff was recently briefed by ARRL on pending amateur radio matters at the FCC. Roderick added, “We need the partnership of the FCC and Congress to ensure our rules and spectrum continue to support the march of technological innovation in our vibrant Amateur Radio Service.”

Multiple proceedings to update or change the FCC’s amateur Part 97 rules to account for changes in technology and operating practices have been languishing at the FCC, some going back five or more years. ARRL is hopeful that these will be addressed soon.

The Senate Committee approved Rosenworcel’s renomination with a bi-partisan vote on December 1, 2021. She has served on the FCC since 2012, and the Committee’s vote to approve her nomination for an additional term sends it to the full Senate for final consideration.

Expert Electronics MB1 Prime 2021 HF – Ham Radio Livestream

Thu, 12/02/2021 - 8:00am

Is the MB1 Prime 2021 an HF Ham Radio or a computer? Or both? On today’s lunchtime livestream, I will hook up this radio and attempt some POTA chasing, after we go over all of the details of this feature RICH ham radio!

Expert Electronics MB1 PRIME (2021 Version)

The MB1 PRIME transceiver is a game-changer, it’s a transceiver and a PC in a single package. It has a classic design, developed over several decades, with the most advanced DUC/DDC SDR technologies – Direct Down Conversion (DDC) and Direct Up Conversion (DUC) and a fully-featured high-end personal computer with an Intel Core i7 processor onboard.

The main advantage of the MB1 PRIME 2021 over its predecessor has improved TX IMD3 AND all-new PC hardware:

  • GIGABYTE GA-IMB370TN Industrial ITX Motherboard
  • Intel Core i7-9700 3.00GHz 8-Core/8-Thread CPU (4.70GHz Turbo Freq)
  • 16GB DDR4 RAM
  • Samsung 970 EVO 500GB SSD (Solid State Drive)

Transceiver Features:

  • Independent RX path based on DDC(Direct Down-Conversion) architecture
  • Independent TX path based on DUC(Direct Up-Conversion) architecture
  • 2software RXs + SubRX for each of them (4 slices total) + independent wideband Bandscope up to 80 MHz
  • ExpertSDR2 software in two styles: Desktop style and MB1 display (for integrated GUI)
  • Remote controloperation, using it, you connect PTT and CW-key to the E-Coder panel. Microphone and E-Coder are connected to the remotely set up PC
  • TCI interfacefor seamless connection with third-party software
  • Professional TX processing moduleprovides the most advanced tuning capability for voice operation
  • High-quality IPS 7″ touchscreendisplay with a 1280×800 resolution
  • Supports any software applicable for Windows 10 OS
  • ExtCtrlconnector to control external devices with 8 powerful keys with open collector
  • COM-portfor connection of external devices, like PA, antenna switches etc.
  • ALCconnector for external power amplifiers*
  • Has a special XVTRconnector for VHF transverters** (SMA connector)
  • 4separate programmable PTT outputs for external power amplifiers
  • An opportunity to use the transceiver as a signal generator via DAC OUTconnector (SMA connector)
  • An opportunity to use external filters in the middle of the RF path, using RX INand RX OUT (SMA connector)
  • Monitoringdelay in CW mode is about 5-6 ms
  • Input for external 10 MHz reference oscillator
  • An opportunity to use the transceiver in SO2Vmode
  • Full duplexor half duplex modes***
  • 4 HF (UHF (SO-239) connector) and 2 VHF(N-type connector) antenna connectors
  • Internal power-meter for HF and VHF bands and SWR-meter for HF band
  • Recordand play on air fragments (IQ files) with a bandwidth of up to 312 kHz
  • Internal ATU(Automatic Tuner Unit)
  • The embedded power supply unit

* ** *** These functions are supported by the transceiver’s hardware but is not implemented in the ExpertSDR2 software. They will be supported in the future ExpertSDR2 software releases.

PC Capabilities:

  • Installation of digital modes software
  • Installation of HAM and Contest logs
  • Two CW Skimmers may be used on different bands
  • The transceiver can connect to the LAN and the Internet
  • Use of Internet applications (e.g., e-mail, Skype, ICQ, TV, etc.)
  • Play video and audio files
  • Watch TV via USB-receivers
  • An opportunity to connect two external displays, keyboard, mouse
  • An opportunity to connect external speakers to the PHONES jack on the front panel

Application area 

  • Full-function radio amateur transceiver
  • Mobile contest-station
  • Remote receipt point for the contests and other applications
  • Spectrum analyzer with the bandwidth up to 80MHz
  • Work with the external programs of digital connection types, CW Skimmer, etc.


A version of ExpertSDR2 software with adapted GUI for 7″ display was specially developed for the MB1 transceiver. At the present time software works in RX/TX mode and supports two independent receiving channels with the bandwidth up to 312 kHz. A DSP library developed by company Expert Electronics allowed improvement of receiving quality and higher the stability of the software.
