k6jm: I am curious how many people who follow the Round Table have higher-power hotspots and which modems they are using. The xxxSPOT combined modem/miliwatt-level radio boards (like ZUMspot) are popular. But how many people are instead running 5-20 watts?
k6jm: For higher-powered hotspots or repeaters, which modem do you use? ZUM Radio's MMDVM-Pi Board www.hamradio.com/detail.cfm?pid=H0-016486 ? Repeater Builder RB_STM32_DVM www.repeater-builder.com/products/stm32-dvm.html ?
k6jm: Or the Nano TEENSY www.micro-node.com/index.shtml ? Or something else?

VA3TWT: I am using a DVRPTR v1 on my public facing hotspot. Running at 25 watts.
k6jm: Thanks K6FED, KJ6OOV, N7PGI, WB5EKU and VA3TWT for your reports about the modems and higher-power radios you are using. I personally have a ZUM MMDVM v1.0 modem vintage 2016, firmware on connected Arduino Due into a Pi 3, with Kenwood D700 at 10 watts.
k6jm: IC-9700 -- have not done a price search, but notice Universal Radio will sell it for $1,900. Remember it supports D-Star digital data similar to the old ID-1 on 1.2 GHz.
N0RSR: SSTV can be encoded and decoded with android or PC apps, The ISS will be transmitting SSTV within the next week or two
k6jm: With increasing combo of ham radio and computing, many modes now automatically display info from callsign lookup sites like qrz.com. We can or will be able to configure to display callsign, name, location.
N0RSR: as an additional thought after seeing a few of the 2019 RSA conference videos, I'm almost scared to connect to any other internet hotspot

k6jm: Regarding attempts to tie radio id to location, note the DMR id tried to have the 1st 3 characters identify the country, but that has run into problems. See www.radioid.net/
N0RSR: VPN use still tosses out your MAC address and wireless connection, also Bluetooth even in non discoverable mode basically shouts out to anyone listening "I'm not discoverable"
k6jm: Regarding easy ways to connect a DV hotspot to a WiFi system (e.g. in a hotel, cruise ship etc.) -- check out products like HooToo's travel router. See www.hootoo.com/hootoo-tripmate-ht-tm05-wireless-router.html
N0RSR: The video that made the most impact for me was this one: youtu.be/pJXCZ1kAOGA
k6jm: Mike -- yes lasers can go through walls. You do have to deal with the new holes in them, though.
