Backlog Report. Another month has come and gone. Surprisingly, I only have one singular game to talk about this time around.

Harvestella

This game had the unfortunate start of being announced when the Switch was already being flooded with farming simulators, so a fair amount of people wrote it off by virtue of over saturation. Those that were more interested in it mostly looked forward to it as “Final Fantasy Meets Stardew Valley.” However that comparison is mostly because people don’t play RPGs or Farm Sims, so it’s really just the first example they can list off the top of their heads. I feel like “Rune Factory x NieR x Etrian Odyssey” is a much more accurate comparison.

I’ve played a fair amount of Rune Factory, but it’s never really been an obsession for me. I’m not too deeply motivated to keep farming and greeting villagers daily for their own sake. I prefer more meat and density to my games than wide sandboxes. To that end, Harvestella fit my tastes to a tee, as it places a much higher focus on narrative compared to RF. It has a very unique take on fantasy/sci-fi fusion, and doesn’t take too long to set up its mysteries and hooks. I’m a sucker for ‘Seemingly medieval world swerves hard into science fiction’ type of stories.

As for presentation, it’s absolutely gorgeous. The environments are varied, appropriately themed, and bursting with color and personality. (Except for the places where they don’t, but that’s no purpose.)

Here are a few screenshots to illustrate:

However, there is one problem with the presentation: No Voice Acted Dialogue. Not every game needs voice acting, mind you. It’s just as much a consideration as a capped frame rate, or a pixelated art style, or cel shading. Not every game will run at 120FPS at 2160p resolution, or use Star-studded industry legends in its cast. However Harvestella is odd in that the playable characters do have voice acting, but only in battles. It hampers the cutscenes a bit because the models rely on reusable animations a lot, and without any kind of snappy voices, cutscenes can feel stiff. There’s also the shock of taking a character into battle and Wow Brakka sounds exactly Nothing like what I was reading him. It’s just odd to me because more than enough games at least use a ‘character is [blank] emotion’ type of sound bytes as extra character-specific punctuation marks. They had enough budget to give all their characters battle lines, but couldn’t extend that to include an ‘AriaShockedGasp.mp4”?

The gameplay is a little bit basic. It’s not particularly innovative in its farm sim or job-changi action rpg halves, but it is very solid, with a sizable amount of customization and a satisfying loop of rewards. Hell, there were moments where I shunted story progress entirely just to do all the sidequests I could. The bosses in particular are some highlights to me, as the unique Break system makes each and every one of them a puzzle in how to maximize damage, and when to press your advantages.

In summary, Harvestella by no means reinvents the wheel. It does, however, provide a smooth and fun ride while it lasts. It has a demo on the eShop, I highly recommend you play that and see if it hooks you.

EDIT: Oh yeah, I forgot to mention: the music kicks ass so hard.

ROKAF F-4E Phantom Fires Live AIM-7M Sparrow Missile

March 15, 2024 Military Aviation

ROKAF F-4E

The last South Korean F-4Es took part in a live firing exercise that saw one Phantom fire an AIM-7M Sparrow Air-to-Air Missile.

Between Mar. 11 and 15, 2024, the Republic of Korea Air Force (ROKAF) conducted live air-to-air and air-to-ground firing training that involved about 40 aircraft of all types, including the F-35A, F-15K, KF-16, F-16, FA-50, and F-4E, as well as U.S. F-16s.

The exercise saw the aircraft tasked with the interception of low-flying cruise missiles launched by the enemy and then with precision air strikes on the origin of the enemy’s firepower: a scenario that simulated the possible escalation of the long standing crisis between South and North Korea.

When the “air-to-air missile live-fire training target”, acting as an enemy cruise missile, was launched, the F-15K, F-35A, FA-50, KF-16, F-16, and F-4E each launched air-to-air missiles to hit the target. The F-35A fired the AIM-9X so as the F-15K fired; the KF-16 fired the AIM-9L and the AIM-120B air-to-air missiles; the F-16 employed the AIM-120B; the FA-50 used the AIM-9L whereas the F-4E fired an old AIM-7M air-to-air missile.

After the enemy launched long-range artillery, ROKAF F-15K, KF-16, and F-16 jets launched air-to-ground missiles and dropped PGMs against the enemy launch sites: the F-15K used the AGM-84H air-to-ground missile and the GBU-31/38 JDAMs; the KF-16 fired the AGM-65G Maverick, the SPICE-2000 air-to-ground bomb as well as the GBU-31/38s; the F-16s dropped the GBU-31; the FA-50 fired the AGM-65G.

The video below shows the South Korean fighters employ a wide array of weapons during the drills. Remarkable, is the segment showing the Phantom firing an AIM-7M, the latest variant of the radar-guided, air-to-air missile Sparrow introduced in 1982 and featuring improved reliability and performance over earlier models (dating back to the mid 1970s) at low altitudes and in electronic countermeasures environments.

The F-4Es are about to be retired from active service after a 47-year career within ROKAF: the first of 94 Phantoms were inducted into active service in 1977. The service also operated the F-4D and RF-4C which have already been retired, respectively in 2010 and 2014. Both the F-4E and the F-5 fleets will be replaced with F-35A Lightning II, FA-50 Golden Eagle and KF-21 Boramae combat aircraft.

The ROKAF F-4Es are based Suwon Air Base located about 20 miles to the south of Seoul. Suwon is the homebase of the 10th Fighter Wing, the parent unit to the 153rd Fighter Squadron, flying the F-4E Phantom.

Only a dozen F-4Es and about 20 F-5s were still in service at Suwon AB last year.

Pyramidal vs. Wedge Absorbers: Which Is Best for Your Application?

In the field of electromagnetic compatibility (EMC) testing, antenna measurements, and radar systems, radio frequency (RF) and microwave absorbers are critical components. These absorbers reduce unwanted reflections, absorb stray signals, and create controlled environments for accurate measurements. Among the most widely used absorber shapes are pyramidal and wedge-style designs. While both serve the same general function, their structure, performance characteristics, and ideal use cases differ significantly. Choosing the correct type for your setup can directly impact your testing accuracy and overall efficiency.

This article explores the core differences between pyramidal and wedge absorbers, highlighting their strengths, limitations, and most suitable applications. Whether you're designing a new anechoic chamber or upgrading your current RF shielding system, understanding these distinctions will help you make an informed decision.

Understanding the Role of RF Absorbers

RF and microwave absorbers are materials specifically engineered to absorb electromagnetic waves. By converting RF energy into heat through conductive and resistive processes, these materials reduce signal reflections in test environments. This is especially important in high-frequency applications like EMC testing, radar cross-section measurements, and wireless communication evaluations.

Absorbers typically come in various geometric configurations, each designed to target specific frequency ranges and spatial constraints. Two of the most prevalent shapes are pyramidal and wedge, which differ in design approach but serve similar foundational purposes.

Pyramidal Absorbers: Precision in a Broad Spectrum

Pyramidal absorbers are characterized by their sharp, pointed tips and gradually sloping sides. Constructed from carbon-loaded foam, these structures work by providing a gradual impedance transition between air and absorber material, which significantly reduces signal reflection. Because of their shape, pyramidal absorbers perform exceptionally well over a wide range of frequencies, often from 30 MHz to well above 100 GHz.

One of the most appealing features of pyramidal absorbers is their broadband performance. Their tapering shape makes them effective at absorbing lower-frequency signals, which tend to reflect more in conventional environments. As a result, pyramidal absorbers are commonly used in full-size anechoic chambers, military radar systems, and advanced antenna testing facilities.

They also offer considerable flexibility in size, with height options ranging from a few inches to over three feet. The taller the absorber, the better its performance at lower frequencies. This scalability allows users to tailor the setup based on frequency requirements, budget, and available space.

Advantages of Pyramidal Absorbers

Wide frequency absorption range, including low frequencies

Ideal for high-precision testing environments

Effective in minimizing reflections in 3D test spaces

Scalable sizes to match application needs

Meets demanding performance standards (e.g., NRL 8000 I-III)

Wedge Absorbers: Compact and Directionally Efficient

Wedge absorbers are another widely used type of RF absorber. Unlike the pointed structure of the pyramidal variety, wedge absorbers feature a gradual slope that narrows to a thin edge. This design helps direct incoming electromagnetic waves into the absorber’s depth, where they are dissipated as heat. The tapered profile provides excellent control over signal propagation, particularly for targeted applications.

These absorbers are especially useful in situations where space is limited, or where side-lobe suppression is a priority—such as in antenna pattern testing or radar simulations. Their shape allows them to reduce reflections coming from off-axis angles more efficiently than pyramidal absorbers in certain configurations.

Additionally, wedge absorbers are easier to install in tight or irregularly shaped chambers. Their lower profile makes them suitable for use on sidewalls or ceilings, especially in smaller enclosures where space economy is essential.

Advantages of Wedge Absorbers

More compact design, ideal for limited space

Efficient at suppressing side lobes and indirect reflections

Suitable for controlled, directional test setups

Customizable to specific shape and size requirements

4-Element Yagi antenna for the 2m band

This blog post discusses the engineering design, construction, and performance evaluation of a 4-element Yagi-Uda antenna specifically optimized for the 2-meter amateur radio band, focusing on the frequency range of 144MHz to 145.5MHz. The project was initiated to establish strong and reliable communication with distant VHF repeaters of the RSSL (Radio Society of Sri Lanka), which are located approximately 58km and 96km from my location.

The primary objective was to develop a high-gain, directional antenna with a superior front-to-back ratio. This directionality is essential for maximizing signal capture from the desired repeater while minimizing interference and noise from unwanted directions, ultimately improving the SNR and the quality of the communication link.

VHF communication at these distances typically relies on line-of-sight propagation, making antenna gain a critical factor in overcoming path loss and achieving reliable signal levels.

The antenna design was carried out using MMANA-GAL, a well-known and validated software suite based on the Method of Moments (MoM) for antenna analysis. While MoM simulations require significant computational resources, they deliver accurate predictions of antenna performance. This is achieved by breaking down the antenna structure into small segments and solving Maxwell's equations to determine the current distribution. This approach enables precise modeling of antenna impedance, radiation patterns, gain, and front-to-back ratio.

Key design parameters were iteratively optimized within MMANA-GAL to achieve the desired performance:

Target Frequency Band: 144MHz - 145.5MHz, encompassing the primary 2m amateur band frequencies.

Characteristic Impedance: 50Ω, to ensure impedance matching with standard RG-58 coaxial transmission line and transceiver equipment, minimizing reflected power and maximizing power transfer to the antenna.

Front-to-Back Ratio Optimization: Aiming for a high front-to-back ratio to minimize reception from the rear hemisphere, reducing interference and improving signal clarity, especially in noisy RF environments.

SWR Minimization: Achieving a VSWR as close to 1:1 as possible across the target frequency band. Low VSWR indicates efficient impedance matching and minimal power reflection back to the transmitter.

The simulation process involved adjusting the lengths of the elements and the spacing between them for the reflector, driven element, and directors of the Yagi antenna. This antenna operates on the principles of constructive and destructive interference of electromagnetic waves. The reflector, positioned behind the driven element, reflects waves forward, while the directors, located in front of the driven element, help to focus the radiated energy toward the main lobe. This arrangement increases both the forward gain and directivity of the antenna.

The optimized design, after multiple simulation iterations in MMANA-GAL, predicted the following performance metrics:

Simulated Gain: 13.1dBi. This represents a significant gain increase over a dipole antenna (approximately 2.15dBi) and translates to a substantial improvement in signal strength.

Simulated Front-to-Back Ratio: 15.35dB. This indicates that the power radiated in the forward direction is over 15dB stronger than in the backward direction, providing good directivity and rejection of rearward signals.

Simulated Input Impedance: Close to 50Ω across the 144MHz - 145.5 MHz band, ensuring a good match to standard 50Ω transmission lines.

The construction of the antenna focused on durability, lightweight design, weather resistance, and good electrical conductivity, all while keeping costs reasonable. We used 10mm diameter aluminum alloy tubes sourced from Lanka Aluminum. This diameter was selected because it is commonly available at many aluminum stores.

For the boom, we use a rigid 19.05mm (3/4 inch) square aluminum box bar, also sourced from Lanka Aluminum. This material is made from a similar aluminum alloy to ensure structural integrity and to serve as a common ground plane for the parasitic elements. The square profile enhances torsional stiffness compared to a round boom.

To effectively secure the components, we use 10mm ABS element holders. These holders are commonly utilized here to construct VHF/UHF TV antennas. Both the plastic holders and 10mm end caps are sourced from Kumarasinghe Radio.

The Polychrome junction box, measuring 85×85×50 mm and designed for outdoor use, is waterproof with an IP55 rating. This rating indicates that the box provides protection against dust ingress (although some dust may enter, it won’t cause harm) and shields against water jets from any direction. This makes it an essential choice for long-term outdoor deployment, ensuring the critical dipole feedpoint remains protected.

We used corrosion-resistant M3 stainless steel nuts, bolts, and washers to secure all elements and the IP box.

Precise assembly is crucial for achieving the intended performance of a Yagi antenna. All elements, except for the driven dipole, were directly and electrically bonded to the aluminum boom. This is a standard practice for Yagi antennas, as it utilizes the boom as a common ground, simplifying construction. Electrical connections were established using M3 stainless steel bolts that passed through pre-drilled holes in the aluminum tubes and boom, ensuring reliable electrical contact. The element holders provided mechanical support and maintained precise spacing between the elements, as well as a 90° angle with the boom, in accordance with the design specifications from MMANA-GAL.

The IP55 box containing the dipole was securely mounted to the underside of the aluminum boom using M3 stainless steel fasteners. To ensure consistent height with other elements, we used a strip of 10mm acrylic sheet.

Antenna VSWR and input impedance were measured across the frequency range of 144MHz - 145.5MHz using a VNA. The measured SWR of 1.1 at 145.025MHz confirms excellent impedance matching at the desired operating frequency. A Smith chart, generated by the VNA, visually represented the antenna's impedance characteristics throughout the band. It demonstrated that the impedance remained close to the target of 50Ω, indicating a broadband match across the intended operating frequencies.

The antenna was deployed at the designated operating location and oriented towards the target RSSL VHF repeaters. A subjective performance evaluation was conducted by attempting communication with the repeaters at distances of 58km (Yatiyanthota) and 96km (Piduruthalagala). 

Reports from repeater users consistently indicated an S9+ signal strength, showing a significant improvement in reception when compared to a baseline mobile whip antenna.

You can find the complete design of this antenna, including all dimensions, in the PDF linked here. The Fusion 360 design file for the antenna is also available here. Additionally, the MMANA-GAL design file (in .mma format) can be downloaded from this link.
