Last year, while the COVID-19 pandemic continued, the total number of visitors to Ham Fair was 35,000, with 25,000 on the first day and 10,000 on the second day, according to the official Japan Amateur Radio League (JARL) data. However, this year, after the disease was reduced from a category 2 infectious disease to a category 5 infectious disease, 31,000 visitors came on the first day and 12,000 on the second day. The total of 43,000 visitors over the two days was the same size as in 2019, before the COVID-19 pandemic occurred.

The opening ceremony was attended by The Japan Amateur Industrial Association (JAIA) President Kenichi Kojiyama, JH3SED, The Japan Amateur Radio Development Association (JARD) President Tetsuya Miki, JA1CIN. The International Amateur Radio Union (IARU) President Tim Ellam, VE6SH, Korean Amateur Radio League (KARL) President Choi Hyeong Moon, HL4CFN, and representatives from 15 wireless federations as guests from Japan and other countries.

8J1HAM Special Anniversary Station

The 8J1HAM special anniversary station was set up at the event site and attracted a large number of visitors who wanted to operate it even before the event opened. Reservations were closed in no time at all. In addition, a quota for youth and female hams was set up. About 100 people operated the station over the two days.

A booth was also set up to introduce the 8J1RL Antarctica Showa-Base Station. A presentation was titled "Antarctica! Meteorites, Ice, and 8J1RL," and iceberg ice, rocks, and meteorites collected in Antarctica were on display. Visitors could actually touch the ice and rocks. The meteorites were displayed in a case because they were valuable and were being exhibited for the first time.

Visitors were also able to talk directly with former Showa-Base personnel who had been assigned to the base and ask questions about the base and the exhibits.

JAIA booth area

JAIA has several member companies that supply products related to amateur radio. Each company exhibited their ingenious ideas in the JAIA booth area. The following is an introduction in order of the booth number.

Icom exhibited the IC-PW2 HF/50 MHz 1 kW linear amplifier, and the IC-905 144-5600 MHz (optional 10 GHz) transceiver. which began shipping just before the fair. While last year’s, visitors consulted with engineers and asked questions through robots, this year, engineers were stationed at the booth to talk directly with visitors and answer their questions. As a surprise announcement, a prototype IC-R15 handheld broadband receiver was on display.

The IC-905 is displayed on the left side of the booth and the IC-PW2 on the right.

The IC-PW2 was demonstrated in combination with an IC-7851 and SO2R with two IC-7610s. The IC-PW2 release date was not given, but a booth staff member explained that the design was in the final stages of development.

In addition to the IC-905, which was launched in Japan just prior to the ham fair, a prototype 24 GHz transverter, parabolic antennas, and a proprietary Cavity BPF (for 10 GHz and 24 GHz) were also on display.

・JVCKENWOOD Corporation
JVCKENWOOD exhibited their TS-990 TRIO logo marked model HF/50 MHz band transceiver, as well the TH-D75 144/430 MHz dual band transceiver, which was announced at the Dayton Hamvention held in the May 2023. They also set up a small van in the booth to resemble an outdoor operation.


The limited-edition TS-990 TRIO model was announced for sale by lottery at JVCKENWOOD stores in Japan in a limited number of three units. According to a staff member, the application process began on 8th August, and the number of applications has far exceeded expectations.

The AZR-5002 144 MHz band 500 W linear amplifier and the AZT-1000 antenna tuner were on display.

HF-50 MHz 1kW linear amplifier AZR-1000 and antenna tuners on display.

The AZR-5002 144 MHz band 500 W linear amplifier is capable of 500 W output with a single FET and supports CW/SSB/FM/FSK/PSK. A staff member said that although a prototype model was displayed, it is scheduled to be released at the end of 2023.

In addition to whip antennas for the 144 MHz and 430 MHz bands, Yagi antennas and aluminum elements for antenna tuners, CPATU and ATE350 were also exhibited.

Diamond Antenna booth.

Two types of antenna for outdoor-mounted antenna tuners were exhibited: The CPATU is a 4.6 m-long aluminum antenna with three trap coils in the middle. It covers frequencies from 3.5 to 50 MHz and has a 200 W (SSB) input rating. The company plans to release the product, but the timing has not yet been determined.

The other type for antenna tuners is the previously marketed as the ATE350, a 6.5 m long aluminum element without a trap coil. This was also prototype since it is not a current product. Both models were connected to Icom AH-730 and AH-705 ATUs and displayed as if they were actually installed.

Four types of whip antennas were on display.

The first is a 1.9 MHz band option to be added to the SD330 screwdriver antenna. The model’s name has not yet been decided. The overall length is approximately 2 meters when combined with the SD330, and the input rating is 200 W (SSB).

The second is the HF217, (tentative name) a 7/21 MHz dual-band antenna with an overall length of approximately 1.67 meters.

The third is the CR627S, (tentative name) a 50 (FM)/144/430 MHz band mobile antenna with an overall length of approximately 1.4 meters. It is an updated version of the CR627 that was once sold.

The forth is the EL2E, (tentative name) an updated version of the EL2E, which was sold about 30 years ago. The EL2ER is a 7/8λ whip antenna, while 5/8λ whip antennas are currently the mainstream.

All of these four types of whip antennas are still under development, and their models and specifications are subject to change.

The DJ-X100 digital multi-mode receiver, released in mid-April of this year, and 144/430 MHz FM mobile and handy equipment were exhibited. The DR-DPM62W, a 351 MHz band digital simplex radio was also on display.

ALINCO booth

Not only radio equipment, but also the company's power supplies, were on display.

The DR-DPM62W is capable of communicating using the "Air-InCom." application software, and digital simplex radio operation on the 82 newly allocated channels.

The DR-DPM62W has three call modes.
(1) Digital Convenience Radio direct calls
(2) Calls between application radio users (LTE to 5G)
(3) Gateway calls between Digital Convenience Radio and App Radio (direct wave + LTE to 5G)

In areas where direct signals are received, the system operates as a simple digital radio, In areas outside of direct wave coverage, it can be used as an application radio using a smartphone paired to the unit with Bluetooth. Both ways can be used to make calls by pushing the PTT on the radio's hand microphone.

General Exhibits

The Club booth area had a total of 145 booths, including 86 general exhibition and sales booths and 59 other exhibition and presentation booths, a slight increase over last year's 137 booths. In the general exhibition booths, there were booths selling kits and booths selling parts and junk items, where people lined up immediately after the start of the event, Booths selling parts and junk items were very crowded with people looking for bargains. There were many displays of elaborate productions and activities. This year, the booths were spaced widely apart to allow for exhibits and sales of goods, but at busy times, the aisles were filled with people, making it difficult to pass through the booths.

General booths on the first day

The monthly FB NEWS also participated in the exhibition. The "Twitter & Facebook New Followers Campaign" and "Communication Experience Corner" were held as booth events, all of which were well-received. CDs by Masaco, JH1CBX, a singer and songwriter were also on sale. Since this was her first international event after COVID-19, she autographed CDs purchased by visitors all over the world.

As a member of JL3ZGL (FB Girls Radio Club), Masaco operated 430 MHz FM at the monthly FB NEWS booth at the event.

The opening ceremony and some of the event areas were broadcast live on YouTube. An archive is also available, so those who missed it can watch it there. However, the video is in Japanese, and is not translated into English.
