Wild guess is it is a power supply issue. But, regardless of the cause some flag bit is set when it fails and that bit is checked on startup. Powering completely down resets the bit.

If you can't hear the repeater on the regular 675 channel, then you must be running tone squelch, or "Private Code" on that channel that is not the same tone as the repeater. ...otherwise you would hear it. 675 is 462.675 on receive whether you are on repeat mode or not. That is exactly what tone squelch is for... so you DON'T hear anything but other radios with your selected tone.

Negative, DXCC entities and sovereign nations are 2 different lists. Lookup current DXCC Entities for the complete 325 recognized entities. These include islands/territories that are controlled by major nations but are not geographically located in those nations - i.e. - Guam, Samoa, USVI, BVI, Easter Island... My count of 300 is the total combined multipliers from all 6 bands. The main bands averaged 70 mults with 20m having 91.

I built a 1/4 wave ground plane antenna using some stiff bus wire and a PCB style BNC connector after doing some simulations with EZNEC to check the bandwidth. The elements were just soldered on. The bandwidth I achieved was 430 to 470 MHz with an SWR of 1.6 or less. The SWR dropped to around 1.1 or so around 450 MHz. I wanted a cheap antenna to use at the Dayton Hamvention good for Ham and GMRS/FRS. I mounted it on top of a baseball cap while keeping the power at 1 watt or less. The elements were only 6 inches long and held it on top using a zip tie through the fabric. Worked far better than the rubber duck antenna with the radio hanging on my belt because the antenna was up in the clear. I tried several of those clip-on type antennas where you use an HT antenna on them and clipped to a hat etc. I see a lot of people using them. None were worth the effort that I tried. Really poor match when I checked them.
