The new Yaesu FTDX10: Yaesu’s latest hybrid SDR HF transceiver

I’ll admit it: I like what I see here.

Yaesu has announced their latest compact 160-6 M transceiver: the FTDX10. Based on the specifications, it looks like it borrows heavily from the FTDX101 series, which is a very good thing.

At 5″, the color TFT display is larger than that of the IC-7300 & IC-705. The specifications appear to be benchmark with excellent dynamic range (3rd IMDR quoted at “109 dB or more”).

We’ll post more details as updates become available. Wimo has listed a pre-order price of €1,550.00 w/out shipping or VAT.

Here’s the full press release via WIMO:


We are pleased to introduce the FTDX10, a new long-waiting compact HF/50MHz 100W SDR Transceiver!

Hybrid SDR Configuration
Like the FTDX101 series, the new FTDX10 utilizes the Yaesu Hybrid SDR configuration – Narrow Band SDR and Direct Sampling SDR. The Narrow band SDR receiver emphasizes excellent receiver performance, while the Direct Sampling SDR provides a Digital Processing Real-Time Spectrum Scope.

Narrow Band SDR with 3 types of Roofing Filters and Phenomenal Multi-signal receiving Characteristics
Like the FTDX101 series, the Down Conversion type receiver configuration with the first IF at 9MHz has been adopted. It makes it possible to incorporate excellent narrow bandwidth crystal roofing filters that have the desired sharp “cliff edge” shape factor. Thanks to the Narrow Band SDR with the latest circuit configuration including 500Hz, 3kHz and 12kHz roofing filters and lownoise oscillator, the RMDR (Reciprocal Mixing Dynamic Range) reaches 116dB or more, the close-in BDR (Blocking Dynamic Range) reaches 141dB or more, and 3rd IMDR (third-order Intermodulation Dynamic Range) reaches 109dB or more, in the
14MHz band at 2kHz separation.

250MHz HRDDS (High Resolution Direct Digital Synthesizer) affords Quiet and Clear Reception
The local circuit of the new FTDX10 uses 250MHz HRDDS method same as the FTDX101 series. Thanks to its characteristics that improve the C/N (carrier to noise) ratio and the careful selection of components in the design, the phase noise characteristic of the local signal achieves an excellent value of -145dB or less in 14MHz at 2kHz separation.

3DSS (3-Dimensional Spectrum Stream) on the 5-inch Full-Color TFT Display with Touch-Panel Functionality
The 5-inch Full-Color panel shows the 3DSS display. By touching the frequency display, the numeric keypad is displayed, and the active band and frequency adjustment can be set by direct input. Frequency setting and adjustment can also be performed by turning the MAIN dial or touching the scope display. Similar to the FTDX101 series, the MULTI display, RX operation status display, Center, FIX and Cursor modes are available at WiMo.

Front Panel Designed for Superior Operating Efficiency
MPVD (Multi-Purpose VFO Outer Dial), is a large multi-purpose ring around the outside of the VFO dial that enables control of
Clarifier, C/S (custom selection function) and recall of memory channels.

Remote Operation with optional LAN unit (SCU-LAN10, see WiMo Website)
Remote operation of the transceiver is possible with the optional SCU-LAN10 and SCU-LAN10 Network Remote Control Software. In addition to controlling the transceiver basic operations, the versatile scope displays enable sophisticated operation such as monitoring the band conditions on a large display at a location away from the ham shack by connection to a home LAN network.

The features of the new FTDX10 include:
– 15 separate band pass filters
– Effective QRM rejection with the IF DSP (IF SHIFT/WIDTH, IF NOTCH DNF, DNR, COUNTOUR)
– High-quality and super stable final amplifier utilizing the new push-pull MOSFET RD70HUP2
– Aluminum Heat Sink with 80mm low-noise axial flow cooling fan
– High Speed Automatic Antenna Tuner with a large capacity 100-channel memory – RF & AF Transmit Monitor
– Microphone Amplifier with Three-stage parametric Equalizer (SSB/ AM mode)
– QMB (Quick Memory Bank)
– Band Stack Function
– Optional speaker – SP-30 designed for the new FTDX10
– Optional roofing filter (300Hz) – XF-130CN available

The new FTDX10 will be available in early December 2020 at WiMo.

CHA MPAS Lite: A proper quick-deployment field antenna

Chameleon Antenna recently sent me a prototype of their latest antenna: the CHA MPAS Lite.

The MPAS Lite is a compact version of their MPAS 2.0 modular antenna system and designed to be even more portable.

Chameleon Antenna is a specialist antenna manufacturer that makes military-grade, field portable antennas that are low-profile and stealthy. Chameleon products are 100% made in the USA and their customers range from amateur radio operators to the armed forces.

Their antennas are not cheap, but they are a prime example when we talk about “you pay for what you get.” In all of my years of evaluating radio products, I’ve never seen better quality field antennas–they’re absolutely top-shelf.

Zeta

I’m currently in my hometown doing a little caregiving for my parents. I’d only planned to be here for a couple of days, but when I saw that the remnants of Hurricane Zeta would pass directly over us with tropical storm force winds and rain, I stuck around to help the folks out.

Zeta struck quite a blow, in fact. No injuries reported, but over 23,000 of us have been without power for over 34+ hours in Catawba county. With saturated grounds, the winds toppled a lot of trees and damaged power lines.

Yesterday, I wanted to take advantage of the power outage and get on the air. I couldn’t really do a POTA activation because I needed to manage things here at my parents’ house. Plus, why not profit from the grid being down and bathe in a noise-free RF space–?

I decided to set it up in their front yard.

CHA MPAS Lite

I had never deployed the MPAS Lite before, so I did a quick scan through the owner’s manual. Although the MPAS Lite (like the MPAS 2.0) can be configured a number of ways, I deployed it as a simple vertical antenna.

Assembly was simple:

  1. Insert the stainless steel spike in the ground,
  2. Attach the counterpoise wire (I unraveled about 25′) to the spike
  3. Screw on the CHA Micro-Hybrid
  4. Screw the 17′ telescoping whip onto the Hybrid-Micro
  5. Extend the whip antenna fully
  6. Connect the supplied coax (with in-line choke) to the Hybrid-Micro
  7. Connect the antenna to the rig

Although I had the Icom IC-705 packed, I wanted to keep things simple by using the Elecraft KX2 I’d also packed since it has a built-in ATU.

Important: the CHA MPAS Lite requires an ATU to get a good match across the bands.

I wasn’t in the mood to ragchew yesterday, but I thought it might be fun to see how easily I could tune the MPAS Lite from 80 meters up.

I checked the Parks On The Air spots page and saw NK8O activating a park in Minnesota in CW:

He was working a bit of a pile-up, but after three calls, he worked me and reported a 559 signal report. Not bad at 5 watts!

I then moved to 40, 18, and 20 meter and called CQ a couple times to see if the Reverse Beacon Network (RBN) could spot me. I like using the RBN to give me a “quick and dirty” signal report. I was very pleased with the bands I tested:

Those dB numbers are quite good for an op running 5 watts into a vertical compromised antenna.

The KX2 very effortlessly got near 1:1 matches on every band I tested.

Of course, after working a few stations in CW and SSB, I tuned to the broadcast bands and enjoyed a little RFI-free SWLing. Noting 13dka’s recent article, I’m thinking on the coast, the MPAS Lite will make for a superb amateur radio and SWLing antenna.

Durability

Although the remnants of Zeta had effectively passed through the area three hours prior, it was still very blustery outside. I was concerned gusts might even be a little too strong for the 17′ whip, but I was wrong. The whip handled the wind gusts with ease and the spike held it in place with no problem.

One of the things I have to watch with my Wolf River Coils TIA vertical is the fact it’s prone to fall in windy conditions and many ops have noted that this can permanently damage the telescoping whip (the weak point in that system).

I’m pretty certain this wouldn’t happen with the Chameleon 17′ whip–it feels very substantial and solid.

Ready to hit the field with the CHA MPAS Lite!

I’m a huge fan of wire antennas because I believe they give me the most “bang-for-buck” in the field, but they’re not always practical to deploy. I like having a good self-supporting antenna option in my tool belt when there are no trees around or when parks don’t allow me to hang antennas in their trees.

I’ve got a park in mind that will make for a good test of the CHA MPAS Lite: it’s a remote game land with no real parking option. I’ll have to activate it on the roadside–an ideal application for the MPAS Lite.

FCC’s AM digital order did not include DRM

This news item expands on our previous post.

(Source: Radio World)

No Luck for DRM in the AM Digital Order

Digital Radio Mondiale was hoping that the Federal Communications Commission would consider allowing its technology as an all-digital option for AM stations in the United States, along with HD Radio. But the FCC disappointed it.

[…]“Many commenters agree that all-digital AM broadcasting should be allowed but object to HD Radio as the sole authorized transmission technology,” it wrote.

“Specifically, commenters urge us to consider the Digital Radio Mondiale all-digital transmission technology on the grounds that it: (1) offers equal or better sound quality to HD Radio at lower bitrates; (2) can transmit metadata as well as emergency alerts, multicast subchannels, and a data channel; (3) is energy- and spectrum-efficient; (4) uses a superior audio codec; (5) is not susceptible to interference; (6) is not owned or controlled by a single company; and (7) has been used successfully in other countries and is the approved technology for shortwave broadcasting in the United States.”

But the FCC said the request was “beyond the scope of this proceeding.”

It said it needed to move expeditiously on this all-digital proposal; and that if parties believe that it should re-evaluate HD Radio and consider alternative technologies, “we would need to evaluate a fully developed proposal including data such as laboratory and field testing, similar to the petition for rulemaking that formed the basis of this proceeding.”[]
