Isnt long wave where amateur radio got its start anyhow? We've come full

I'm surprised the Flex-5000 is so deaf. My 1500 receives perfectly well down
to about 480 something kilohertz, then the bandpass filter clicks out and all
heck breaks loose. Lots of room to hear most of the 600m band. I guess
there's something different in the hardware...well, there's a ton
As I have mentioned, I and many other hams have the desire to listen down at
those frequencies with our Flex radios. What I have not heard is an official
comment on the specifications are at below 1.8 mhz. From what I have heard it
is best just to use an upconverter that will output at a

Yeah, probably. Heinrich Hertz' initial experiments were in the microwave
spectrum but Marconi ended up going for longer and longer
Ken, I was likewise surprised by your statement about successfully using the
Flex-1500 to receive 600 meter ham beacons. I've read Flex discussion
boards for several years. To the very limited degree that users comment on

I bet Flex has or, or plans to do, some market research to determine if it
is viable to develop an upgrade, accessory, or new product that is capable
of 600m. I imagine being first-to-market with a radio that can cover the
new band could be good for business.

Exect for Heinrich Hertz, whoes work was at about 1 meter (300 MHz), long
wave is where EVERYTHING started.

My Flex-5000 is utterly deaf below the U.S. AM broadcast band. Can't even
pick up local airport Non-Directional Beacons.
My F5K has RX2 installed. I have noticed that the sensitivity of RX1 is 37
dB poorer than RX2.
AT 7 MHz, the gain difference between the two receivers is only 1 dB.
And
Decided to take a look at the 60M band capability of the Flex 5000A. Not sure
what I am doing wrong but I get no power out on Channel 1. The other four
channels appear to work fine. What am I missing?
Thanks,

Hi Jeff,
I bought the Flex-1500 to use mainly as a mediumwave DXing receiver. The fact
that it transmits is a bonus. Our local ham dealer said he has sold many 1500s
to SWLs. As a DXing receiver it's $250 cheaper than the SDR competition and
does the job very well. The 3000 and 5000 have
I just checked on my 1500 and what I notice is that when I change frequency
from 481 kHz to 480kHz whatever filter is currently in the front end is
removed/bypassed because and the receiver front end is wide open to everything
from mediumwave stations to hams participating in the ARRL DX
Surprised at your observation, I checked my 5000a and noticed that if
RX1 preamp is off, I get same results on both RXes at 485 KHz, but if
RX1 preamp is on, the baselines are different and I see an apparent
difference of 30-something dB.
Are you using the same settings on both receivers?

One other thing that would be nice is to have an option to bypass the
built-in front-end filters thus allowing selection of an external
filter.
It's not an option, but that's what my 1500 does right out of the box. The
front end filters (appear to) cut out when I tune down from 481 kHz. All
The FLEX-1500's low frequency hardware band pass filter starts to roll
off @ 490 KHz very rapidly.

Look to see of the DRIVE setting is different on that channel as opposed
to the others.
You can also try a reset to Factory defaults in the Setup form.

Hi,
I have a Flex3000, when I plug a straight key in the front panel, with the

If I pull the key plug part way out of the key jack, it works normal. what do I
