A look at the new ICOM IC-7760 HF & 6m transceiver

At the 2024 Dayton Hamvention in the USA in May, ICOM gave away some details about a new product called the 'X-60'. I covered this in an earlier post HEREΒ 

In late August 2024, it was finally revealed by ICOM that the new product was the IC-7760, a fully featured HF & 6m transceiver with a 200-watt output power.

As can be seen above, the radio comes in two parts... a control head and a RF deck. These are the dimensions...

RF Deck - 425 Γ— 149 Γ— 442 mm (16.7 Γ— 5.9 Γ— 17.4 in)

Control Head -Β 340 Γ— 118 Γ— 103.5 mm (13.4 Γ— 4.6 Γ— 4.1 in)


The radio has two receivers which allows for the monitoring of one band while tuning another. The two receivers can also be locked to each other allowing diversity reception. It's possible say to listen to one receiver with a horizontal antenna and the other receiver to a vertical antenna. You can listen with headphones and hear the received signal with one polarization in one ear and the other polarized signal in the other ear.


The rear of the Control Head has a number of connections including a RJ-45 socket to connect a LAN cable to the RF Deck. This could be a few metres or up to 100 metres. The obvious attraction here is that the RF deck could be placed at the bottom of a mast and doesn't need to be inside the house. This obviously reduces the need to run coax cables into the house.

There is also provision for an external monitor to show the displays in more detail if required.


The front of the RF Deck is pretty bland while the rear panel has a host of connections.

The unit is mains powered which eliminates the need for a high power 13.8 volt supply. There are multiple RF sockets as well as multiple other connections.


There's no doubt that it's a superb looking radio with a lot of features but what about the price?

The current guideline seems to be around the $6,000 mark. In the UK, it seems to be about Β£5,700. WIMO in Germany are saying €6,600.

I suspect for most, this is an eye-watering price that is just way too expensive. After all, it is at the end of the day just a HF & 6m transceiver and any good operator could work 99% of the stations with a radio costing a quarter of the price.

I'm sure there are a minority though that could justify the price for a fully featured radio with a fully rated 200-watt output.

Over the weekend, WIMO Germany released this video previewing the new radio.

Remote Operation... One thing that is not totally clear is whether remote operation is possible?Β 

The one obvious thought is that someone might want to say put the RF Deck in a holiday home while keeping the Control Head at home and connecting the two over the internet. Apparently this is not possible due to latency issues.

ICOM's solution is to use their Dualwatch compatible IP remote control software to control the remote radio. As the chart shows below, the IC-7760 is a supported radio.


I would assume that this has more limited functionality as compared to a direct connection from the Control Head to the RF Deck.

Version II of 15-10 Rig -- Updates on Bal Mod, AF amp, and RF Amp, DX

Version II of the 15-10 rig is mostly done. I did a lot of work on the AF amp, balanced modulator, Mic amp, carrier oscillator, and filter. Dean KK4DAS and I continue to test and measure the RF power amplifier. I describe the brutally simple, non-sequenced T/R switching arrangement, and the spread-out open air construction style.

Version I of this rig is on its way to the Dominican Republic. Version II will stay in Virginia. I have already worked a lot of SSB DX with this rig, including, Thailand, Taiwan, China, India, Kenya, Australia, American Samoa, and others.

This video was inspired by the recent work of Nick M0NTV and Charlie ZL2CTM. And of course, Pete Juliano N6QW.

The DL2MAN / PE1NNZ (tr)uSDX: A Pocket-Sized 5 Band QRP Transceiver

Are you looking for a super compact, portable QRP transceiver for your BOTA, POTA or SOTA ham radio operations? Then read on and watch DL2MAN’s video about his (tr)uSDX non-clone QRP transceiver.

Introduction:

Since I recently got a Venus-Tech SW-3B, I had not paid much attention to the (tr)uSDX rig from DL2MAN/PE1NNZ until now. YES! I am a BIG sucker for QRP stuff and just had to add one of these pocket sized rigs to my QRP stable. So, I pulled the trigger and placed my order for an assembled rig with AliExpress. AliExpress was listed as one of DL2MAN’s Where to Buy recommendations.

The (tr)uSDX is a 5-band, multi-mode transceiver that packs an efficient class E PA and supports CW/LSB/USB/AM/FM. It covers by default 80/60/40/30/20m (alternative filter setups possible). What sets it apart from the tons of clones is that every unit sold has its own serial number. To download the firmware upgrade you must enter your serial number and call sign into the web site. Your unique firmware will then be loaded into the radio, and your call will be displayed on the screen.

Sharing DL2MAN’s video about his design, operation and features of his (tr)uSDX transceiver might be valuable for those who want to learn more about it or considering one of these pocket transceivers for themselves. DL2MAN has a bunch of videos about his design on his YouTube channel.

Key Takeaways:

  • The (tr)uSDX transceiver is a compact, portable, and powerful 5-band, multi-mode transceiver that supports CW/LSB/USB/AM/FM.
  • Each unit sold has its own serial number, and you can upgrade your firmware only by entering your serial number and call sign into the firmware download website.
  • The transceiver is easy to use, and you can change various options in the menus to suit your needs, such as TX drive and noise gate.


Step-by-Step Firmware Upgrade Process:

  • Go to the firmware download web site and enter your serial number and call sign.
  • Download your unique firmware file.
  • Connect your (tr)uSDX to your computer via a USB cable.
  • Open the firmware update software and select your firmware file.
  • Click the β€œUpload” button to start the firmware upgrade process.
  • Wait for the firmware upgrade process to finish.
  • Disconnect your (tr)uSDX from your computer and turn it on.
  • Your new firmware and callsign should be displayed on the screen.

Resources:

  • DL2MAN web site – (Manual) The official website of the creator of the (tr)uSDX transceiver.
  • eHam.net review – A review of the (tr)uSDX transceiver on eHam.net.
  • DX Explorer article – An article about the (tr)uSDX transceiver on DX Explorer.
  • QRPer.com has a video review of the (tr)uSDX,

Conclusion:

The (tr)uSDX is a super pocket-sized QRP transceiver designed by Guido (PE1NNZ) and Manuel (DL2MAN) that has been widely anticipated by the amateur radio community. The transceiver boasts up to 5 watts output power, CW, SSB, FM, and AM modes, a built-in microphone, five bands (80, 60, 40, 30, and 20 meters), a super compact and lightweight form factor, and an open-source hardware and software design.

Based on the web search results, it is clear that the (tr)uSDX is a pocket-sized QRP transceiver capable of working multiple modes on 5 bands at 5 watts, and weighing less than 5 ounces. It has a Micro USB CAT and Programming Interface, and can create 0.5W Output from 5V USB Supply alone. It typically draws 80mA on RX and 500mA on TX at 13.8V with 85% PA Efficiency. The small size of the (tr)uSDX makes it excellent for portable work, and it can be used for CW, SSB, and digital ops as well.

One notable aspect of the (tr)uSDX is that it is an open source project and available for a very reasonable price. According to one review, the assembled transceiver is sold below the $150 price point, which is impressive given its capabilities.

Overall, the (tr)uSDX appears to be a powerful and portable transceiver that can be used for a variety of modes and bands, and is available at a very reasonable price point. Its open source design also allows for customization and modification, making it a popular choice among radio enthusiasts.

VHF Low Pass filter for DRA818V module

Β It is best to use the DRA818V VHF voice transceiver module with a low pass filter.

Since I'm building a VHF/UHF transceiver using the 818V and 818U modules, the VHF low pass filter was missing from the build.

Β 


This design was based from the one here and only some small values changes made , I placed adjustable cap's on the center elements (the 56pF), so used 10-60pF trimmer cap and used 32pF on the ends (10+22pF parallel).Β 

Schematic:


Β After build did some measurement on the spectrum analyzer:

Final iteration of the trimmers:


Β Attenuation at 200Mhz:


Filter shape from 100 to 300Mhz without normalization:


...now I need to finish the remaining of the transceiver..

Β 

Have a great day!
