Default VX-8r Bug?


One bug that I cannot duplicate is when just listening to the broadcast band (radio) and switching from FM to AM band, the knob would not tune the frequency.


Second bug:

Radio Setup:
APRS mode enabled (A12 blinking)
WX Alerts turned ON
Dual Recieve with A-Band scanning VFO (6) and the display set to show the frequencies.

As I was watching the 220MHz scan, the radio automatically switched to the MR weather memory (1). There was no audio, but the WX station was received full strength. From this state, I pressed the UP ^ scan button and the audio came on. It was then possible to use the dial to scroll through the 10 weather memories, but that is all. I tried to change the volume, but the volume showed 10 and would not change. Pressing A-Band or B-Band, or the MENU buttons had no effect. I was effectively locked in this state. I also noticed that the display would flicker on irregular intervals, sometimes the WX freq would flicker, sometimes both frequencies would flicker. I do not think I was receiving an actual weather alert, so I'm not sure why the radio switched to the WX stations.

I powered off the unit off and was able to get into the menu to disable the WX alerts. I tried the same setup again and the behavior was repeated. I also found out that I can get out of this situation by pressing F/W 9 to exit the WX stations. When not scanning, the radio does not switch to the WX stations, just when the scan is enabled.

Mine's broke!

While in single band just picking up APRS traffic, I decided to turn on the Spectrum Analyzer and find a repeater. After engaging the SPA:

the keys Menu, F/W, Moni, Band...actually, none of the keys do anything anymore, and there is no audio on strong stations.

I can use the dial and scroll through the frequencies and cycle the Menu key through the APRS screens, but I cannot scroll the station list and cannot enter any of the setup menus.

Wonder if this is indicitive of the radio and current firmware or if mine is just a lemon?

I haven't been able to replicate any of those problems. Of course, I don't have any weather alerts coming through, either. But I do have WX reports on channel 1.

I do note that some functions are disabled while using the Spectrum Analyzer, but I don't seem to have the problem you're having. Maybe you should take yours and exchange it?

That's actually good news as it means, you got a good one, but more so that it's not a problem with the design.

Mine recovered after doing a reset, so it just needs to be put it through its paces for a while.

I have an issue that may or may not be a bug. I can transmit on 6m with it plugged into the stock changer, but anything on 2m or above, it power cycles the radio. Is that by design? I unplug it and it can transmit freely on any band.

It is probably trying to use the charger as the power source, which does not put out enough power.

Try setting the power down to 1/2W or less and try it. I think mine would work on lowest and maybe 1/2W.

Is your 6m set to AM mode? I think it puts out less power in AM mode there.

That's not a bug, the supplied adapter is meant for charging and does not supply enough power to transmit, at least not on full power.

I have the same problem while scanning. It goes through the weather channels for some reason and then gets stouck on what ever it can pickup, then scans for about 4 seconds on 220 and does it again. I found if I turn off weather alerts memory #111 (I think) the problem goes away. Is your weather alert turned on?

My weather alert was turned ON. If I turned it off, I did not have this problem.
