Beware of cheap underperforming clones

As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

2026 SVHFS Conference Call for Papers

Papers and presentations are solicited on both the technical and operational aspects of VHF, UHF and microwave weak signal amateur radio. The deadline for the submission of papers and presentations for this year’s conference is March 2, 2026. Some suggested areas of interest are:

* Transmitters
* Receivers
* Transverters
* Beacons
* RF Power Amplifiers
* RF Low Noise Pre Amplifiers
* Antennas
* Construction Projects
* Test Equipment and Station Accessories
* Station Design and Construction
* Contesting
* Roving

* EME
* Propagation (Sporadic E, Meteor Scatter, Troposphere Ducting, etc.)
* Digital Modes (WSJT, etc.)
* Digital Signal Processing (DSP)
* Software Defined Radio (SDR)
* Amateur Satellites
* Amateur Television

In general papers and presentations on non-weak signal related topics such as FM repeaters and packet will not be accepted but exceptions may be made if the topic is related to weak signal. For example, a paper or presentation on the use of FM simplex in contests or on the use of APRS to track rovers during contests would be considered.

All submissions for publication in the proceedings should be emailed to SVHFS@downeastmicrowave.com ( SVHFS@downeastmicrowave.com ) in Microsoft Word (.doc) format. No Power Points will be accepted for use in the Proceedings.

Submissions for presentation at the conference should be in Microsoft PowerPoint (.ppt) format and can be delivered at the conference on a USB memory stick.

Paper: Size should be 8½ ´ 11-inches.

Margins: Top and sides should be 0.75 inches; bottom must be 1 inch.

Font: You may use any font you’d like. The font should be clean and easy to read (12 pt Arial, Helvetica, Tahoma, or similar sanserif are good choices).

Layout: Either a one or two-column format is fine.

Page numbers: DO NOT NUMBER THE PAGES. This will be taken care of in the Proceedings’ final layout at the ARRL.

Headers/Footers: do not use headers and footers. They can cause the book page breaks to be erratic and cause excessive editing later.

Drawings: Drawings should be embedded in the files. Place them where you’d like them to appear.

Photos: Color or black-and-white digital images and graphs should be embedded in the text where you’d like them to appear.

We do not copy edit (but will correct something if we notice it – or if you notice it and let us know). We do try to make all papers somewhat uniform, but we don’t edit each article.

The deadline for the submission of papers and presentations is March 2, 2026. Please indicate when you submit your paper or presentation if you plan to attend the conference and present your paper in person or if you are submitting solely for publication.  Papers and presentations are being handled by Don Woodward KD4APP, and should be sent to SVHFS@downeastmicrowave.com ( SVHFS@downeastmicrowave.com ).  Don can be contacted at dbwoodw@w-ent.com ( dbwoodw@w-ent.com ) if you have any questions.
