Handheld that can receive 600 mHz range?

Sorry. Not paying attention. By 0.800 MHz does he mean 800 KHz, because that's what THAT would be or am I wrong again?

The Kenwood TH-F6 will cover the 600 mhz range for the microphone. Can be priced high unless you get a used radio on Ebay.

What you're thinking is correct, .800 mega-hertz would be 800 kilo-hertz. Normally the k is lower case though. You'd think that those with a positive power would all be capital and those with a negative power would be lower case, but not in this world. The abbreviation "M" indicates 1,000,000 while the lower case version "m" indicates 1/1000.
With these you just have to memorize them and hope for the best. At least with radio frequencies, it pretty much doesn't matter what case they use, it's pretty easy to tell what they were trying to say since frequencies rarely go into the negative powers.
I wondered if anyone was going to elaborate on the whole issue of using m vs M ... as I knew it went over the head of many reading here. Don't get me started on the proper use of the language; using ' when they are not needed; your vs you're; their, there & they're; or calling the number zero an oh. This is actually something listed as a no-no in one of the stickies.
I knew what the OP meant, even with the the use of mHz because we are talking about wireless mics and I know that many use the TV band. That's what matters.

As long as I know (or is it mnow, now 
) that mHz means Khz, I'm cool. I hope you still SAY KHz when speaking, because saying "small m Hertz" or something like that would just sound dumb. It bothers me that people state a zero as an oh, too. With years - like 1906 (nineteen oh six) - it is easier and I except that one. My biggest one about numbers is when people state a decimal as a plural, like saying 0.6 miles (point six miles) instead of 0.6 mile! I also state decimal digits as singles so you don't think it is a whole number, like with 1.12. I say one point one two, not one point twelve. I also add the preceding zero, as you have seen with decimals (0.6 not .6) so the demimal is noticed.
Anyway, I have seen a scanner on Scanner Master that receives the "regular" AM radio band which starts lower than 800 mHz at 540 mHz (as we all should know). Unfortunately, I can't remember which one.

Milli is a submultiple. Multiples, not submultiples, are the commonly used SI units, which is why there is a general lack of understanding of mHz and MHz.
The academic community takes some of the blame, as any institution of higher learning that claims to have any scientific credibility, will have it's students use multiples every time. Stupid, and not very clean looking, IMNSHO, especially when I can write out something much shorter by using a combination of submultiples and multiples rather than just multiples and have to add useless digits.
Also, I think the 330T is the scanner you're thinking of. AFAIK, Scanner Master is the last place to still have them

Cliffnotes: A scanner is not the answer (for a variety of reasons) Baby (or in this case priest) monitor or a hard wired speaker to the rectory is the way to go. Far less money involved, low tech, and more reliable and effective. Simple and cheap is always a plus.

I don't know how the SI world can consider KHz - there, I said it! - as a submultiple when everthing is a multiple of the hertz ... 1000, 100 000, 1000 000 000 etc. I would say this forum website is the only place I am likely to see "mHz" rather than "KHz".
Thank You for the 330T reference.

I also may have messed you up in my original post because I was wrong. Sorry about that.
800 mHz = 0.800 Hz (m = "milli")
800 MHz = 800,000,000 Hz (M = "Mega")
I am not aware of any scanner on the market that covers 0.6 Hz (600mHz) or 0.8 Hz (800mHz) for that matter.
An Icom R10 handheld should work. IIRC, it has a wide FM mode. The audio might sound a little funky given that the transmitted audio was compressed and the R10 won't expand any of it. It may sound compressed but you should at least be able to hear it.
Good luck.

I have the same or similar book. From the table, I can't see how millihertz (mHz) is the same as kilohertz (kHz), which is the way it seems to be used several posts earlier?

The correct abbreviation for megaHertz is mHz, with the H capitalized because it's a person's name. Some style books, ARRL's among others, use MHz but that's their choice, not necessarily correct but the way they want to do it. What WAS incorrect in the post above was calling 0.800 mHz the same as 800 mHz, which it obviously is not.
Back to the subject at hand, understand that the reason the wireless microphone engineers design their systems with compression is so that they can have high fidelity AND narrow transmit bandwidth, and that's what will give you problems if you try to reproduce the transmitter's signal with an improper receiver.

sennheiser makes 600 MHz units...

I don't understand what Sennheiser has to do with this thread. The OP has a Shure UHF system. Different manufacturers use different compandoring techniques, as well as different frequencies, even in the same bandsplits. Sennheiser, along with SONY, is also one of the most expensive lines of wireless microphone systems, plus their stuff all has to come from overseas. I've been there and done it all with the wireless guys and found that the smart people stick with Telex and Shure, to name just two of the "good guys" in the business. There are a few others as well.

Wrong, Wrong, Wrong.
Even the Regulatory Authorities eg., FCC, ITU, etc., use M for Megahertz, and k for kilohertz.
