DRMNA: Interview with Mike of PantronX, maker of the Titus II

titus 2 big

Those of you following the upcoming Titus II receiver will enjoy reading this interview with Mike of Pantronix. Here’s a short excerpt taken from

[DRMNA] Can you tell us a little about the process taken to develop the new receiver?

[Mike] We became aware of the need for a digital capable receiver by a visit from TWR representatives about three years ago. Having designed RF products and receivers in the past, it intrigued me that there were no low cost method to receive DRM. This began research into the problem. Initially we envisioned and designed what we call an ATU (Antenna Tuner Unit) that plugged into a ‘standard’ Android tablet. Unfortunately as time and testing proved, ready made tablets had varying problems from vendor to vendor, model to model. The decision was made about a year ago that we had to do our own Android ‘tablet’ and integrate the ATU into it. Hence the Titus II was developed.[…]

Radio Eritrea and Radio Ethiopia jamming intrudes on amateur frequencies


Many thanks to SWLing Post contributor, Vlado (N3CZ), for sharing the following story from the South African Radio League newsletter:

Broadcasters, jammers wreak havoc on amateur radio frequencies

The ARRL reports the battle in the amateur radio 7 MHz band continues between Radio Eritrea and Radio Ethiopia, which is said to be jamming the Eritrean broadcaster with broadband white noise

The problem for radio amateurs is that the battle is taking place in the 40 meter phone band 7,145 and 7,175 MHz with the jamming signal reported by the IARU Region 1 Monitoring System (IARUMS) to be 20 kHz wide on each channel.

The on-air conflict has been going on for years; Ethiopia constructed new transmitting sites in 2008 and is said to use two or three of them for jamming purposes. The interfering signals can be heard in North America after dark.

According to IARUMS Region 1 Coordinator Wolf Hadel, DK2OM, Radio Eritrea is airing separate programs on each frequency. He said in the IARUMS September newsletter that telecommunications regulators in Germany, Austria and Switzerland have been informed, so they could file official complaints.

Dave’s review of the MFJ-1026/1025 and regulated AC adapter recommendations


Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who shares the following reply to TomL’s post More Anti-Noise Ideas:

My VERY NOISY Sony CRT TV has gone to the great electronics recycling bin in the sky thank goodness. But I still have a MFJ-1026 here and need to use it when the neighborhood gets noisy. Intermittent power line noise is the main issue these days for me.

[Note that] my Monitoring Times review from April 2007 on the MFJ-1026 (and 1025 model without the preamp, but is best to have it) is still available here :

(is also linked on my web page, with many other of our other favorite ones : )

jameco-ac-adapterI still power it with a analog REGULATED Jameco 170245 12 volt (1 amp) ac adapter.

Last batch I purchased a few years ago were still 100% clean and analog regulation. As I have covered in the past, SOME of Jameco excellent REGULATED AC adapters have gone to using switching regulator devices inside (and these no longer clean for any radio use).

DX Engineering is about to come out with a improved version of the premium priced NCC-1, called the NCC-2. Mid late November Delivery ?? Never had our hands on one the pricey NCC-1 critters as the MFJ gets the job done for us (let alone affording it).

You make an excellent point: it’s important to power your noise-canceling device with a quality, clean, regulated AC adapter.

Thank you for sharing the links to your review and the AC adapter recommendations, Dave!

Shortwave Radio Recordings: Voice of Korea

north_korean_propagandaMany thanks to SWLing Post contributor, Paul Walker, who shares the following:

This is the English service broadcast for The Voice Of Korea to “Latin America” from Kujang, North Korea. Recorded 0430-0530UTC October 17, 2016 using a Tecsun PL-880, Wellbrook ALA1530LNP, EmTech ZM2 antenna tuner and DXEngineering HF Preamp.

Listening location is Galena, Alaska. A village of 500 people in the rural central interior, 300 miles east of Nome and 300 miles west of Fairbanks.

I would give this a SINPO Rating of 66666!

Check out this image taken of the front of the Tecsun PL-880 while listening to this broadcast, showing just how strong the signal is.


I was a bit surprised, never seen something this high before, especially on shortwave!
