 ======= Icom IC-7100 =======
-An older offering from Icom, this is a great little radio. For us UK hams we get HF/2m/70cm including 5MHz and 70MHz. It's architecture is the older IF DPS design so it's hackable to include IF / RF taps if you want to add a panadapter. KV5R has [[https://kv5r.com/ham-radio/2018-projects/7100-panadapter/|done a great write up]] on IF tapping the radio. The IF is apaprently pretty high at 124.487 MHz, making it slightly less than trivial to use a buffer amplifier, but his process appears to give a reasonable IF output without dragging down the stage too much.

 ===== Low transmit power on SSB =====
-Some of these radios appear to have a problem with their ALC circuit (and / or possibly the compressor) causing them to put out low-ish power on transmit. The radio I have doesn't do this, but there are two potential solutions to this, according to the interwebs.

 . Upgrade the firmware, there are reports that Icom fixed this by changing ALC / Compressor parameters \\
