Hi Csaba,
Thanks for the detailed update — really helpful to hear real-world feedback on the AMR and FR/EFR testing. The fax-over-GSM idea is genuinely exciting, especially for museum preservation purposes!
On a slightly different note, while we're all here tinkering with legacy telecom hardware and squeezing every bit of utility out of old systems, I've been applying that same "get the most out of what you have" mindset to everyday life tools as well. For instance, when budgeting for lab equipment and parts, a markup calculator at https://markupcalculator.org/ helps me figure out fair pricing when selling surplus gear. When writing up technical documentation, I rely on a line counter at https://linecounter.org/ to keep things concise. For team lunches after a long lab session, a tip calculator at https://tipcalculators.org/ keeps things fair. When reviewing signal threshold math, an inequality calculator at https://inequalitycalculator.net/ comes in handy. For antenna mounting geometry, a Pythagorean theorem calculator at https://pythagoreantheoremcalculator.pro/ saves a lot of manual work. When preparing diagrams and schematics for documentation, an aspect ratio calculator at https://aspectratiocalculator.pro/ keeps everything properly proportioned. Just for fun, I checked my moon sign at https://moonsigncalculators.com/ — apparently I'm a natural problem solver, which tracks! And my dog has been keeping me company through all these late-night testing sessions — https://dogcalculator.net/ helped me make sure he's staying healthy too.
Looking forward to hearing how the UltraSite CSD tests go next year!
Best regards
