Tecsun PL-660: A simple hack to scan the air band

8 Replies

Many thanks to SWLing Post contributor, Bruce F, who writes:

HI Thomas, I thought I would put this idea out to your site – in case it isn’t already there. It’s a brilliant solution to the apparent lack of a working Air Band scan function on the Tecsun PL-660.  Note – I did not come up with this idea, but came across it in a Yahoo group.

It IS possible to scan the Air Band on the PL660, as long as you have picked out WHICH Air Band frequencies are in use in your area. There are websites which list these frequencies for each airport:

Here’s how to set up the PL-660:

  1. Pick an empty page in the Memory.
  2. Put in a shortwave frequency in the first empty space; the “00” slot.
  3. Then fill in the succeeding spaces on that page with the Air Band frequencies you’ve chosen.
  4. Now go back to the “00” slot and hold down the scan button.

Works on my set!

What a cool trick!  I’ve lent my PL-660 to a friend, but as soon as I get it back, I’ll also try this trick by setting up a page dedicated to my local aviation frequencies!

Thanks, Bruce!

Inside the Post: A new perk for Patreon Patrons

6 Replies

Quite often, I’m privy to information that has yet to be refined into a public post here on the SWLing Post. In the past, I’ve simply kept the new information and/or evolving posts to myself.

But as a small perk for supporting the SWLing Post via Patreon, I’ve decided to share this informal information privately through Patreon’s website.

If you’d like to be privy to the background processes and that go into the making of the SWLing Post, you can enjoy them (or ignore them!) here, simply by supporting us through Patreon. What I’ll share is raw, random, and unedited information in the form of progress reports, tips, and even partial reviews. These logs and notes happen when they happen, depending on my time availability, and are off-the-cuff and ever-evolving.

This private “behind-the-scenes” access to the SWLing Post is available to Patreon Patrons at any pledge level.

As I’ve mentioned before, if you don’t have the means to give through Patreon, no worries, friend: we’re always here for you free of charge at the SWLing Post. If you would, however, like to support the SWLing Post through Patreon with a monthly contribution, we welcome you as a Patron.  Your support helps keep the site going, and means I can do more of what I enjoy most––sharing my love of all things radio with you.

Thank you !

Through 11:59 P.M. on 12/13/17, C. Crane is offering 50% off their popular SoftSpeaker & SoftSpeaker2.  These are “pillow speakers” with soft, washable covers – great for listening while drifting off to sleep.

For the SoftSpeaker, use this promotional code: PS17

For the SoftSpeaker2, use this promotional code: SSV17

I must admit, I don’t own either but I’ve often thought about purchasing version 2 because it has in-line volume control.  This would be a great time to try them!

Pete reports new developments with the uBITX transceiver

Many thanks to SWLing Post contributor, Pete Eaton (WB9FLW), who writes:

Last March, Ashhar Farhan (VU2ESE) the designer of the very popular BITX20 and BITX40 series of mono-band HF Transceivers announced a new low cost rig called the uBITX (micro BITX) a full blown 80-10m 10 Watt SSB/CW Transceiver. Now comes word that after many months of very hard development work by Ashhar this much anticipated Rig will soon be available.

For those not familiar with the project this is *not* a kit, rather like its sibling (the BITX40) it consists of two assembled and tested Circuit Boards. The RF board measures 5.5 x 6 inches and a second small plug in daughter card that takes care of the digital portion of the design including the 2X16 LCD, Arduino Nano, and Si5351 which are used in the VFO.

Add a cabinet, knobs, and connectors and you have a full blown HF Rig! An added plus is that except for the Gerber PCB files everything else (including the firmware) is Open Sourced!

The original description can be found here:

Farhan has just released the Firmware, Schematics, and Wiring Diagram for the production version on GitHub

Wiring Diagram:

https://github.com/afarhan/ubitx/blob/e481ea2a2457fc4e7be7a6a4bc9a0fba12bf2cde/ubitx_wiring.png

Farhan has a social conscience as well giving several local ladies much needed employment for final assembly and checkout of the Rigs.

There are still a few final tweaks being done to the design so pricing is still to be determined. But if it’s offered at a similar price point as his earlier Transceivers it should sell like hotcakes!

Wow!  Amazing project!  Thanks for the tip and updates, Pete!
