new mini-modules: applications

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. 73, Wayne N6KR --- http://www.elecraft.com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Hi,
Please post a sample of the output from the Wattmeter together with supported COM port speeds etc. Those of us who pound the keyboards every evening will no doubt be asked to add support which is not so easy when you don't have one.

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. 73, Eric WA6HHQ ---------- wayne burdick wrote: > 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.

Is moving the BNCs and the battery box to the back of the board enough
to allow it (WM1 or Audio Filter) to mount cleanly in an enclosure or will other components on the board prevent the LEDs or pots from poking the right distance through the enclosure wall? - Keith KD1E - -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Eric Swartz - WA6HHQ, Elecraft Sent: Wednesday, September 27, 2006 1:07 PM To: wayne burdick Cc: Elecraft Reflector Subject: Re: [Elecraft] new mini-modules: applications 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.

Kieth,
If the LED height over the other components is a concern, one could even mount the LEDs on the back side of the board and the other components on the front, although I suspect there is plenty of room - the transverters and KAT100 front panel combine the LEDs with other (lo-profile) components on the front side of the board. I believe the real answer is: if it is too tall, move it to the back side, each enclosure choice may have its own considerations to deal with. 73, Don W3FPR > -----Original Message----- > > Is moving the BNCs and the battery box to the back of the board enough > to allow it (WM1 or Audio Filter) to mount cleanly in an enclosure or > will other components on the board prevent the LEDs or pots from poking > the right distance through the enclosure wall? > > - Keith KD1E - > > -----Original Message----- > From: [hidden email] > [mailto:[hidden email]] On Behalf Of Eric Swartz - > WA6HHQ, Elecraft > Sent: Wednesday, September 27, 2006 1:07 PM > To: wayne burdick > Cc: Elecraft Reflector > Subject: Re: [Elecraft] new mini-modules: applications > > 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.

You could use the nut on the threaded bushing on the switch to mount one end to a front panel. You'd want to support it at the other end. Of course, there are four holes in the corners of the PC board for mounting screws, etc. Pots with long shafts are provided so the knobs are all about the same height above the board. BTW, check out the last page of the AF1 manual at www.elecraft.com under Manuals and Downloads. The response plots are quite impressive! There's a low-pass filter and a bandpass filter. When in bandpass mode, the low pass filter can be adjusted to further improve the high-frequency attenuation above the passband. WM1: With the battery pack on the back of the board, the highest part is the data jack at 12mm. Next are the electrolytics at 10 mm. Mounted directly on the board, the top of LED's are at 8 mm. One way to handle that would be to provide cutouts in the enclosure so the FORWARD POWER, SWR and RANGE LEDs just below them are visible. A bit of clear plastic would seal the enclosure to keep dust, dirt and rain out as well.

Alternately, the LEDs could be mounted higher off the board if your
enclosure demanded it. There are lots of possibilities if you choose your enclosure before building and put the creative mind to work. I personally see no need to have an enclosure at all on some equipment, but each to his own - if used at the operating position, then enclosures make stacking boxes easier, but on the workbench, no enclosure is needed in most situations. 73, Don W3FPR > -----Original Message----- > Keith KD1E wrote: > > Is moving the BNCs and the battery box to the back of the board enough to > allow it (WM1 or Audio Filter) to mount cleanly in an enclosure or will > other components on the board prevent the LEDs or pots from > poking the right > distance through the enclosure wall? > > ----------------------------------- > > AF1: > With the battery pack on the back side of the board, the highest > part is the > rotary switch.
