The new Mountain Topper MTR-4B V2 by LnR Precision

The venerable Mountain Topper MTR-3B

I’ve just noticed that LnR Precision has announced their new Mountain Topper MTR-4B V2.

They’ve released a few details with the promise of photos soon. Looks like the MTR-4B will of course sport four bands (80, 40, 30, and 20 meters) but adds two valuable tools its predecessors lacked: an SWR and RF power meter.

A full 5 watts output power is attained with a 12V supply, but the voltage operating range is 5.5 to 13volts.  The MTR-3B’s (photo above) has an upper operating range of 12V.

I look forward to checking out the MTR-4B and we’ll post photos as soon as they are available.

Here are the details from the LnR Precision Website:

Hamvention Photos: Hendricks QRP Kits

Another very active table at the Dayton Hamvention and Four Days in May is that of Hendricks QRP Kits.

Doug Hendricks (pictured right) and his team produce some amazing, affordable QRP kits that fill many a niche in the shack. Below, I have photos of a small selection of their offerings at the Hamvention.  Note that all of these kits are available on the Hendricks QRP Kits website.

Many of Hendrick’s kits are suitable for beginners. If you’re in doubt about your kit building skills, simply contact the folks at Hendricks and they’ll help guide you to the right kit.

The NUE-PSK Digital Modem

QRPers have long been fans of PSK. And why wouldn’t they? The mode is efficient and uses DSP technology to help discover low bandwidth digital signals.  What that means for the QRPer is: 1 watt + PSK = DX   Very effective use of the juice!

Thing is, PSK has traditionally required the QRPer to bring along some sort of computer and a handful of wires and cables to take PSK to the field.

The American QRP Club has made this easier with the introduction of their portable digital modem–the NUE-PSK. This modem, like other AmQRP products is a kit and requires some experience with surface mount kits.

Here’s the AmQRP description of their modem:

The NUE-PSK is a small 7″ x 4″ x 1″ standalone, battery-operated digital modem using a graphic display for transmit and receive text data, as well as for showing band spectrum and tuning. Just plug in a standard PS2 keyboard and connect to an SSB-capable transceiver like the FT-817 or the PSK-xx transceivers from Small Wonder Labs, and you’ll have an effective digital mode station that goes absolutely anywhere.
