thanks; I guess that explains it - for SLP mode an upper limit of 5:41; too bad. All the other modes have larger capacity for HSD than RTD and about the same as RTR.
Walmart has raised the price of the 533 and 535.
Now $218 and $248.
537 still $279.
Now, all are $30 apart. Had "always" been at least $40 apart. They were selling many more 533's than the others, although they were adding stock of all models at ~same high levels every few days before Xmas. I suspect they *may* be running low on 533's and trying to create more interest in the higher-capacity units to even out inventory. This is just a SWAG since we can't see their inventory levels anymore.
Use the Channel > Manual Channel Preset menu to get rid of that bad 1.103 so it doesn't "interfere" with op of the Mag.
Tuning Interference problems and solutions are described here.
What model do you have now?
You might want to check your FW and see if your 515 might have the very firs BE FW, 724V, and if so, consider updating to SuperFW 727V?
Can't hurt and just might help.
