Re: 125 watt VHF Quantar randomly drops TX
When Quantars do random things it’s time to check the EEPROM in the SCM. Check if it’s the problem Xicor part or the good Atmel version.

No hack is presently possible as the APX radio itself refuses the frequencies even when CPS is hacked to allow entry.

Re: APX 8000 and MPL plus 900MHz
The 800/900 Mototrbo radios (except the e series) work very well on the 900 MHz ham band, no hardware mods and you get DMR which is excellent at 900.
The receivers drop a tad at the low end but above about 915 you’re golden. The XPR repeaters also work really well.

Re: Difference between DR3000 8MB and 32MB
The main difference I remember is that remote IP programming is not available on the 8MB. This prevents you from doing codeplug changes and software updates remotely.
Also, some of the 8MB builds are old and include a strange heating pad on one of the chips to allow operation at cold temperatures.

Re: XTS3000 Programming Issue
It will work well enough on 469.99375 MHz, that's only 1.25 kHz off. Some radios drift that much anyway.
The reason you can't enter 469.9925 MHz is that the synth only does 5 and 6.25 kHz steps, your frequency would need a radio that can do 2.5 kHz steps. AFAIK the 5K can do this OK.
