But, I am curious about the reception range from two international airports and one national airport. There are way too many variables to give a specific answer.
Car will need A/C recharged as the Owner never used it.
Feel free to call or text my friend as he can best describe the vehicle.
I would listen to the scanner using earbuds while on the train going into DC. Pretty much the only analog traffic is aircraft, backup frequencies that repeat a talkgroup from one of the digital systems, and the WMATA/Metro system, which is analog trunked, and has the worst audio quality (even under optimal reception conditions) of any system I've ever monitored.
Being inside metal cars makes for poor reception, and I found that the Diamond antenna helped considerably. I'd strongly recommend the BCD436HP because it has the best receiver, will receive the most digital formats, and the database will let you listen to the dozens of systems in the area without spending hours trying to program them all. Most law enforcement and government traffic in the DC area is on various P25 digital trunked systems that the BC75XLT will not receive.
I could care less about Metro, or any of the other transportation systems. There is also the Montgomery County Sheriffs Office, and Montgomery County Detention Center.
I came across this RR thread from 2011, dealing with virtually the same issue.
https://forums.radioreference.com/ra...There is a LOT of LE activity on the Metro system.
I rode Metro, so I listened to know why there were backups or the train stopped in the middle of a tunnel, especially after the lady died in the tunnel fire.

But the number people who have died by their own stupidity, running to catch the train. Because, While it is Metro's responsibility to keep the system safe.
Because more detail is given, as to the purpose of each frequency. OTOH, While Air Nav's most recent update was less than two weeks ago. I have tried cross-referencing the two, to help me understand Air Nav's details. If something changed but nobody notices the change and submits the correct data then nothing will be updated. It looks to me like Air Nav uses standard abbreviations that sould be listed in the Pilot/Controller Glossary or Aeronautical Information Manual.
If nothing changes then there is no reason to update it. Air Nav shows the current date of the FAA data for each airport, even though nothing may have changed for years.
When monitoring aircraft frequencies, it is common to hear aircraft at much greater distances than the control tower, because there is a clear line of sight to the aircraft but not the tower. I looked into getting a longer antenna but after research for a handheld. Except that an antenna that wasn't a 'rubber ducky' might have better reception. The diamond RH77CA works noticeably better than the factory antenna on most bands, but it is larger. I have my 436 sitting next to me right now monitoring air traffic from Harrisburg, which is about an hour drive away. I am only thinking of the Aircraft Band, Fire/EMS, and Law Enforcement. The local county airport comes in the best since it is only a couple miles from my house.
