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!

Overnight I received the following email:

This is Sylvia from global radio store in Aliexpress platform, I want to inform you that XHDATA D-808 radio will start to selling at American time 2017/12/09 13:00. The sale price is $69.98[…]

I’m sure we’d all like to hear from anyone who takes the plunge on this unit.

The Wacky and Rare Toshiba RP-2000F Now on Ebay

7 Replies

Is this a receiver designed by MacGyver? The Toshiba RP-2000F was a portable radio designed for the 1970s Japanese BCL (Broadcast Listener) and is not often seen on the used market.

A fine example of this model is on the USA Ebay site right now: https://www.ebay.com/itm/TOSHIBA-RP-2000F-Shortwave-Radio-Full-88-108-FM-Dial-Great-Cosmetic-Condition/253300518829

 

The $495.00 starting price is steep, but probably inline with the radio’s rarity and condition. Do any SWLing Post readers have first-hand experience with this model? How does it perform? Let us know in the comments below!

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

Arduino Sketch:

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!

Keith is impressed with the Digitech AR-1780

Many thanks to SWLing Post contributor, Keith Batari, who shares the following:

I have just got the AR1780 and comparing with others I’ve had especially the PL-660 and PL-880 beats them both. Firstly the SSB does have an annoying mute when running, but the sensitivity and sound quality is fantastic, and that goes for all bands.

The airband sensitivity is also impressive with excellent squelch. Long wave sensitivity is low[…]. Tuning is without the quirks of the PL-880 and great on general coverage bands.

Headphones sound great. I’ve opened mine and the build quality is good with band trimmers and transformers.

If anyone has acquired the circuit diagram could the post it on the Google site.

If you want a radio with a lot of bang for your bucks, then look no further.

Agreed, Keith! The AR-1780 is certainly a value performer. Click here to read our comprehensive review.

I should add that while LW performance is not stellar on the AR-1780, it should suffice for LW listening in Europe, for example. The C. Crane Skywave series does not include longwave, so if you’re looking for a compact travel portable with LW service, the AR-1780 is a better bet.

Rocky is pleased with the CC Skywave SSB

Just got my new C. Crane Skywave SSB radio. Same size as my wife’s C. Crane Skywave. AM, FM, WX and Airband all work just as well on the Skywave SSB as the regular Skywave.

So far, I am very satisfied with the SSB reception on the new Skywave SSB. It has one strange quirk – when you press the SSB button, it takes about 3 to 4 seconds to go into SSB mode. Five dashes appear on the display during this wait. After that, it is great.

I enjoy aeronautical communications and I get good reception of San Francisco radio and aircraft flying between the west coast and Hawaii. This is on the built in whip antenna.

Also been tuning through the ham bands and it does a nice job. There is an extra 0.5 KHz bandwidth on SSB mode so it is possible to do some casual CW listening. I like how the “Band” button works on shortwave.

When in AM mode, it cycles through the shortwave broadcasting bands. In the SSB mode, it cycles through the ham radio bands. It even selects LSB on 160-30 meters and USB on 20 through 10.

The only other receiver I have to compare it with (other than my wife’s Skywave) is my 18-year old Sangean ATS-909. The ‘909 is a bit more sensitive on MW AM broadcast band but selectivity is as good or better on the Skywave SSB.

FM sensitivity is great and the FM selectivity of the Skywave SSB beats the ‘909 hands down. Using the built in whip antennas, the Skywave SSB is more sensitive than the ‘909 on shortwave. Haven’t tried the included roll-up antenna on the Skywave SSB yet.

Having a squelch is really nice for monitoring the VHF Airband. One thing the Skywave SSB does that the regular Skywave does not do – you can scan 10 VHF Airband frequencies on the Skywave SSB.

So far, I am very satisfied with this new, tiny shortwave receiver.

Many thanks for sharing your mini review, Rocky!

I’ll also post a CC Skywave SSB review here hopefully by the end of next week–after Thanksgiving travel. My review has been delayed a as my CC Skywave SSB production units have had some QC issues: a very slight internally-generated noise in one and subpar sensitivity in the other.

My pre-production CC Skywave SSB is as Rocky describes: a gem of a compact receiver with sensitivity equal to that of its predecessor and relatively good noise characteristics.

C. Crane engineering is looking into the issues with my early production units and dispatching a replacement. I’ll post an update and review when I receive the replacement.
