The SW300 AM Field Strength and Modulation Monitor

Schlockwood's SW300 is a compact and economical portable field strength meter and modulation monitor for medium-wave AM broadcast applications.  It meets needs ranging from those of Part 15 operators and hobbyists to commercial AM broadcast stations.


The SW300 is supplied with our calibrated Goldring antenna and an AC mains power adapter.  In the field the SW300 may be powered by an optional, readily-available and inexpensive battery pack.

Please download the SW300 data-sheet for application details, features and specifications. Additionally, upon request we will happily email you  a  PDF of the SW300  Manual, the illus-

trated Setup and Operating Guide, that even more thoroughly details SW300 applications and operation.

SW300 UPDATE

"Coming Soon" has finally arrived!

With the industry now catching-up on component supply issues, we are finally able to schedule and build the first formal production run of the SW300 Field Strength and Modulation Monitor.  Barring unexpected surprises, pro-duction units will be ready to ship around the first week of February, 2023.

Limited Time Offer!

We do have a few of the pre-production SW300 units for sale from our field-test program.  These have been brought-up to current production circuitry, and are functionally and cosmetically identical to the final pro-duction design.  They come with our standard Warranty and return privileges and are offered at $400.  Drop a note if you're interested.

And the price?

Despite supply-chain, shipping-cost and inflation-related increases, we're able to hold our initially-predicted selling price at $780.  This includes the SW300, its AC power adapter and the calibrated Goldring antenna.  USPS Priority Mail shipping to US destinations runs $25 or less depending on distance.  (Please see Sales and Shipping Notes below for further shipping stipulations.)

Sales and Shipping Notes:

For the present, the SW200 is sold exclusively on a factory-direct basis.  We are able to accept PayPal, Zelle, money orders, cashier's and personal checks (shipment pending clearance of personal checks).  We ship by USPS Priority Mail, insured by default as er explain below.

As the public turns increasingly to Internet sales, the instance of 'porch piracy' of home deliveries has become rampant.  Once shipped, neither we nor the carrier can be responsible for items pilfered from your porch.  We seriously recommend delivery to a residence with someone at home, to a business address that can accept your shipment, or to specify that the parcel be held for pickup at the post office.

Factory-direct sales to a residential address bear the additional modest expense (at just our cost) of insurance for the full amount of the sale and 'signature required upon delivery,' unless the buyer opts-out of this protection in writing when the order is placedThanks for your understanding toward our mutual protection, and please consider options and implications carefully before opting-out. 

Technical or application questions will be answered promptly, and sales inquiries quoted individually.
