HPSDR PennyWhistle

PennyWhistle Kit

PennyWhistle is a compact RF power amplifier stage that can be used with Penelope and Alex to make a complete 16 to 20 Watt transmitter. This amplifier can quickly and inexpensively be used to get an HPSDR on the air, either barefoot, or as a driver for a larger linear. It covers the same 160 Meter through 6 Meter bands as the rest of HPSDR.

It is 10 cm by 8 cm (half Euro-board size.)

The output stage is a single stage amplifier that uses a pair of TO-220 "16 Watt" Mitsubishi RD16HHF1 parts in push pull and has approximately 19 dB gain, depending where you bias it, so it will deliver 16 to 20 watts output with 1/4 watt drive.

More detailed information is available on the OpenHPSDR Wiki or in the assembly manual.

PennyWhistle Warranty

The PennyWhistle Kit IS SOLD ON AN AS-IS BASIS WITHOUT WARRANTY OF ANY KIND.

This is a low volume production, experimental item. TAPR is a small, not- for-profit organization of volunteers who have helped facilitate this project because we believe it is a cool thing to have. In order for TAPR to be able to offer this board at all, we must rely on the support of all users in the HPSDR community.


Support

Support will be provided via the HPSDR Discussion List.

Because TAPR is not staffed to provide support for PennyWhistle, and because the knowledge to support users resides with the developers and users on the HPSDR Discussion List, buyers should participate in that forum for support.

Firmware and software will be available for download from the HPSDR website.


Ordering Information

The price for the PennyWhistle Kit is:

  • $ 77 US for members of TAPR

  • $ 85 US for non-members

Shipping and Handling

Shipping and Handling within the US will be by USPS Priority Mail.

International shipping costs are calculated as closely as possible. If the actual cost exceeds the estimate by more than $5.00, TAPR will contact you to get approval for the additional funds. TAPR uses insured Priority Mail International, unless the purchaser requires something else.
