True, but they do not typically reveal a lot of details about their communications gear, nor of details of suspected attacks. (Full disclosure -- I lean heavily into the mass(ish) hysteria explanation, I just don't think it tells us much that government entities are not open about some aspects of embassy operations or security!)
I recommend going back a few months to this post and the one after it, and studying the JASON report.
"It is a byproduct, like the sound of a gun, which is not what does the harm." I understand what he's going for, but actually loud noises like gunshots do damage, with symptoms similar to the Havana syndrome, ironically.
Obviously unreliable (could all be Russian disinfo agents), but still...

This happened to a civilian I know in his own home around 2017, in Ohio suburbs. Mid 20’s male, otherwise healthy. It nearly killed him and has taken years to recover (mostly) from. I wonder if this isn’t happening to people in general at a similar rate to that of federal employees. Seems if someone was nefariously targeting these 1000+ people who reported this, some physical evidence would have been collected. I believe the symptoms are very real.

I have experienced same symptoms in 2019 and 2020, and I am not and have never been a USA government employee. That raises a question on the truth whether its targeted towards US service personnel or it's simple a wide spread phenomenon that hasn't been well identified yet

Link to paper (also one of several):A new interdisciplinary study on the “Havana Syndrome” led by Dr. Alon Friedman M.D. of Ben-Gurion University of the Negev (BGU) in Israel and Dalhousie University Brain Repair Center in Nova Scotia, Canada, points to overexposure to pesticides as a likely cause for neurological symptoms among Canadian diplomats residing in Havana, Cuba in 2016.
Based on the results of these three lines of inquiry, most IC agencies have concluded that it is “very unlikely” a foreign adversary is responsible for the reported AHIs. IC agencies have varying confidence levels, with two agencies at moderate-to-high confidence while three are at moderate confidence. Two agencies judge it is “unlikely” an adversary was responsible for AHIs and they do so with low confidence based on collection gaps and their review of the same evidence
Excerpts:
There's also a helpful overview on the meaning of "likely" or "confidence" as used by the intelligence agencies:The IC pursued three separate lines of inquiry: the first encompassed work determining whether available data points to the involvement of a foreign adversary in the incidents; the second focused on the feasibility and existence of deliberate mechanisms that an adversary might use against US personnel to cause AHIs; and the third evaluated whether medical analysis can help determine if an outside actor is involved in the broad range of phenomena and symptoms associated with AHIs. Based on the results of these three lines of inquiry, most IC agencies have concluded that it is “very unlikely” a foreign adversary is responsible for the reported AHIs.
• Agencies employed an array of collection and investigative efforts that spanned hundreds of reported incidents—within the United States and abroad—and explored a range of potential indicators of hostile activity, from identifying suspicious persons near incident sites to searching for a pattern among affected personnel. These efforts could not identify an adversary as being responsible for any incident and in some key cases, IC agencies and partners had comprehensive information on the location where an AHI occurred but found no evidence of adversary activity.
• A review of intelligence reporting, open-source information, and scientific and medical literature about foreign weapons and research programs, as well as engagement with researchers inside and outside the US Government have led IC agencies to judge that there is no credible evidence that a foreign adversary has a weapon or collection device that is causing AHIs. [...] All agencies acknowledge the value of additional research on potential adversary capabilities in the RF field, in part because there continues to be a scientific debate on whether this could result in a weapon that could produce the symptoms seen in some of the reported AHI cases.
• IC agencies assess that medical analysis of AHIs has evolved since the first reported incidents in ways that point away from adversary involvement. While initial medical studies concluded AHIs represented a novel medical syndrome or consistent pattern of injuries similar to traumatic brain injury (TBI), a combination of medical and academic critiques pointed to methodological limitations in that work. Furthermore, the JASON panel’s review of preliminary data from a National Institutes of Health (NIH) longitudinal study on AHIs in 2021 does not convey a consistent set of physical injuries, including neurologic injuries such as TBI. This shift is notable because the initial medical opinions formed a central part of the IC hypothesis that US personnel had sustained injuries that were unlikely to be explained by natural or environmental factors and shaped the IC’s approach to AHIs.
IC agencies assess that symptoms reported by US personnel were probably the result of factors that did not involve a foreign adversary, such as preexisting conditions, conventional illnesses, and environmental factors. IC confidence in this explanation is bolstered by the fact that we identified medical, environmental, and social factors that plausibly can explain many AHIs reported by US officials.
The IC considered a range of other possibilities we deemed less likely, and identified types of information that, if found, would prompt us to revisit our assessment, such as new medical analysis that identified a syndrome linked to affected personnel or the identification of a specific device that both caused the harmful effects described in AHI reports and was fielded by an adversary during the timeframe of the incidents.
Article: The Army in September awarded Wayne State University in Michigan a $750,000 grant to study the effects of radio frequency waves on ferrets, which have brains similar to humans, according to information on the grant posted on USASpending.gov. The aim is to determine whether this exposure induces similar symptoms to those experienced by U.S. government personnel in Havana, Cuba, and China, the documents show.
DoD has also recently tested pulsed radio frequency sources on primates to try to determine whether their effects can be linked to what the government calls “anomalous health incidents,” according to one former intelligence official and a current U.S. official who were briefed on the effort. Both were granted anonymity to discuss sensitive work. It is not clear whether these studies, which were done internally, are ongoing.
Article: Exclusive: Declassified report suggests "Havana syndrome" could result from energy weapon
Full intelligence report contradicts official claims that strange cluster of ailments wasn't caused by attack
March 29, 2023
A newly obtained declassified report prepared for the director of national intelligence by a panel of experts appears to show conclusively that "Havana syndrome" is not a naturally occurring health problem. It does not reach any conclusions about who or what may be responsible, but suggests that an unknown device or weapon using "pulsed electromagnetic energy" remains a plausible explanation.
The document was declassified after the James Madison Project, a nonprofit dedicated to reducing government secrecy, sued to obtain further information on "Anomalous Health Incidents" or AHIs, the official term used to designate the syndrome.
"The U.S. government is covering up evidence as to what AHIs are," said James Madison Project attorney Mark Zaid, who also represents a number of Havana syndrome patients. "This report differs from the summary released earlier this month and previous statements from the intelligence community. It is becoming apparent that these events were perpetrated either by foreign actors, or it is an experiment gone horribly wrong."
...
Some published reports have suggested that the symptoms were characteristic of "mass psychogenic illness," but the declassified report rejects that, finding that the AHIs "do not fit criteria for mass psychogenic illness."
The declassified report even outlines one possible method of causing AHIs, using small devices that consist of "commercial off-the-shelf technology, use mature technology, are easily portable and concealable, and can be powered by standard electricity or batteries. Parametric acoustic arrays — also referred to as directional loudspeakers or acoustic lasers — are the most plausible technology, although other ultrasound technology may be at play."
No line of sight would be necessary, according to the report:
Thank you, that's interesting.
The summary says, maybe such an RF weapon is possible, but we don't have evidence for it.This accurately reflects the full report.
"Some credible evidence that it was technically and practically feasible" ("feasible" is a fancy word for "possible") is a standard a science-fiction writer might employ when coming up with fictional future technology, in effect meaning "does this break any laws of physics?" It's not a hard enough standard to make it plausible that this technology already exists.Article: 
Perhaps a conclusion could be explained by this sentence from the post by @Agent K :
He is not an impartial commentator.The U.S. government is covering up evidence as to what AHIs are," said James Madison Project attorney Mark Zaid, who also represents a number of Havana symptom patients.
He didn't write the article or the report, he just sued to get the report declassified.
Article: (U) Findings
(U) The Panel reached six main findings. Some are limited by knowledge gaps or assessments that could be resolved or tested through implementing the Panel’s recommendations.
(U) The signs and symptoms of AHIs are genuine and compelling. The Panel bases this assessment on incident reports, medical data from affected individuals and interviews with their physicians, and interviews with affected individuals themselves. Some incidents have affected multiple persons in the same space, and clinical samples for the small number of affected individuals who were tested within an appropriate time period have shown early, transient elevations in biomarkers suggestive of cellular injury to the nervous system. The reported signs and symptoms of AHIs are diverse and may be caused by multiple mechanisms, but no case should be discounted. Prompt medical evaluation and care are particularly important; most individuals who were treated soon after an event have improved.
(U) A subset of AHIs have a unique combination of core characteristics that cannot be explained by known environmental or medical conditions and could be due to external stimuli. Although some signs and symptoms of AHIs are common in known medical conditions, the combination of the four core characteristics is distinctly unusual, is unreported elsewhere in the medical literature, and so far has not been associated with a specific neurological abnormality. Several aspects of this unique neurosensory syndrome make it unlikely to be caused by a functional neurological disorder. The location dependence and sudden onset and offset, for example, argue for a stimulus that is spatially and temporally discrete. The perception of sound and pain within only one ear suggests the stimulation of mechanoreceptors, a specific cranial nerve, or nuclei in the brainstem, all of which mediate hearing and balance as well as the sensation of pressure. The lack of other symptoms also helped rule out known medical conditions as well as stimuli that are known to affect other sensory or motor systems.
(b)(3) Electromagnetic energy, particularly pulsed signals in the radiofrequency range, plausibly explains the core characteristics, although information gaps exist. There are several plausible pathways involving forms of electromagnetic energy, each with its own requirements, limitations, and unknowns. For all the pathways, sources exist that could generate the required stimuli, are concealable, and have moderate power requirements. Using nonstandard [redacted] antennas and techniques, the signals could be propagated with low loss through air for tens to hundreds of meters, and, with some loss, through most building materials
(b)(3) Ultrasound also plausibly explains the core characteristics, but only in close-access scenarios and with information gaps. The required energy can be generated by ultrasonic arrays that are [redacted] portable, and produce a tight beam. Ultrasound propagates poorly through air and building materials, restricting its applicability to scenarios in which the source is near the target, [redacted]. It could couple to the body through the external auditory canal, interstitial spaces, or the vestibular apparatus of the inner ear. Ultrasound is used to open the blood-brain barrier in medical procedures, and ultrasonic stimulation of the aforementioned anatomical areas could produce symptoms consistent with AHIs. Studies of “ultrasound sickness” and related audio-vestibular symptoms have reached mixed conclusions, but the Panel was presented with independent accounts in which individuals were exposed to high-power ultrasound beams and subsequently experienced the core characteristics.
(U) Psychosocial factors alone cannot account for the core characteristics, although they may explain some other reported incidents or contribute to long-term signs and symptoms. No known psychosocial factors explain the core characteristics, and incidents exhibiting these characteristics do not fit the majority of criteria used to discern mass sociogenic illness. However, psychosocial factors may compound some of the incidents with core characteristics. Incidents that do not possess all or some of the core characteristics could be due to hypervigilance and normal human reactions to stress and ambiguity, particularly within a workforce that is attuned to its surroundings and trained to think about security. Some of these reactions could lead to functional neurological disorders or worsen the effects of existing conditions.
(U) Ionizing radiation, chemical and biological agents, infrasound, audible sound, ultrasound propagated over large distances, and bulk heating from electromagnetic energy are all implausible explanations for the core characteristics in the absence of other synergistic stimuli. These mechanisms are unlikely, on their own, to account for the required effects or are technically or practically infeasible. Ionizing radiation, for example, produces known biological effects that are easily measured and inconsistent with the core characteristics, and chemical or biological agents alone would not explain the reported location-dependence or directionality.
But he made the simple declarative sentence, "The US government is covering up evidence...". His representation of the patients is not impartial. The report uses many uncertainty phrases like "knowledge gaps", "may be caused", "could be due to", "could produce symptoms", etc. The extrapolation to "covering up evidence" is, as yet, fact-free.
Ultrasound also plausibly explains the core characteristics, but only in close-access scenarios
"Close access scenario", in the only example given in the report which is checkable by us, means sitting in a chair with the ultrasound transducer (the "transmitter") being in contact with ultrasound gel applied to the subject's scalp.Ultrasound is used to open the blood-brain barrier in medical procedures

and yet they summarize it as "plausibly explains", same as with EMF
Lots of diplomats visit my local, due to its "friendly" opening hours (and for business-development attaches, one of their points of contact living only 2 doors away). There's a much simpler explanation for some of the "strange" experiences, and it ain't nothing to do with the dodgy Russians and their embassy only 4 doors away.
