Official release of VU2ESE’s Antuino


Ashhar Farhan VU2ESE, the designer of the BITx range of kit transceivers marketed through HF Signals has launched his next design: the Antuino.

The website states that:

“Antuino is an accurate instrument that can be used in the field to measure SWR, field strength, modulation, etc. In the lab, it can be used to sweep filters, measure gain, distortion, frequency response, etc. It works upto 150 Mhz. On the third harmonic, it is usable on 435 Mhz band as well (with reduced sensitivity).

“The Antuino, unlike simpler instruments is based a superhet architecture that measures the response of the antenna or circuit at exactly the tuned frequency. It is based on Analog Devices’ Lograthmic Amplifier, the AD8307 to provide accuracy of 1db in your measurements. It is tuned with a crystal locked PLL based on Si5351 oscillator chip.”

Ashhar has confirmed that this is not a kit, but rather is a fully tested unit in an all metal case. It has an internal battery case to hold 6 AA cells. It comes with two SMA connectors.
Steve G1KQH has opened a support group for the Antuino:
