Radio Shack HTX 10 Conversion

[crkfngr]

Can a Radio Shack HTX 10 be converted to 11 meters? I have read it is the same as a Magnum 257, except The HTX 10 does not have variable power.

Thanks

no it can not be modified. the very 1st ones that came out could but they only put out a very few then made them where you could not modify them.

Yup that's the only way I know of. In stock trim they are a very FCC pleasing radio.

It can be converted just have to find where they blocked it on the front board. The chip is the same as the ones that can be modded. Lc72322n chip behind the face. The titan 2 has the exact main board & face board. It can be done I just don’t want to damage my Htx10. I’ve had one in its package forever because I’d like it to cover all those bands. I think mine is one of the first ones, date on it is 09-99.

This is incorrect.

Regardless of the marking on the chip, the FIRMWARE IS DIFFERENT ON A HTX-10. It does NOT include the firmware required for anything except 28.000 to 29.699.
Anyone who tells you otherwise has no idea what they are talking about and does not understand how these radios work, OR the significant differences between all of these rigs that "look" the same on the outside.

Unless the PLL chip is changed for one with a different and complete firmware (from a Dragon, Magnum, Titan, Albrecht, etc), or a crystal is swapped out to move the master reference, then the HTX-10 is not able to be modified. And even then, it's literally not worth the trouble. It's not a small job, for a less than perfect result.

It amazes me how long this silly rumor has been circulation. Decades now, and not one single HTX-10 has appeared outside of the 10m band in all that time (with some simple "resistor mod", or similar). And that is for good reason.
