Also, for those who want to mount the WM1 in their own enclosure or
behind a panel, the PCB layout also accommodates mounting the BNC
connectors and battery on the -rear- of the PCB. This then provides
clearance for the bar graph LEDs to poke through an opening.
The LEDs can also be turned off under computer control for when the
meter is used just as a remote sensing device.

To answer some of your questions:
- Our new mini-modules, like the others, are intended as low-cost,
easy-to-build station accessories for experimenters. Any of them can
be built into a case or used with the supplied rubber feet.
- The AT1 step attenuator provides attenuation of up to 41 dB. Thanks
to careful PCB layout, leakage around it will not be an issue for most
bench-test applications, especially at HF. It can also handle up to 2
watts -- more than most attenuators -- useful for QRP transmitter
testing. I've found the small size of the AT1 to be very convenient
during my own lab work.
- We've had many requests for a traditional analog audio filter that
would work with any rig, especially those with simple receivers that
have little filtering of their own. The WM1 is ideal for this.
- The WM1 wattmeter provides fast-response, high-visibility forward
power and SWR bargraphs, which some operators prefer to analog meters
or digital-readout wattmeters. It also has some unusual features for
its price class, including autoranging and computer I/O.
I'll be happy to answer any other questions about the application or
technical details of these new mini-modules. Feel free to post your
questions or e-mail me directly.

Wayne
