AX2Product no.: AX2AX2 MINATURE 20-METER WHIP ANTENNA.
The AX2 is small enough to take anywhere - just in time for light outdoor use during the new solar cycle. Use it HT-style with a handheld tripod like the KX2, on a picnic table with an AXB1 whip tripod, or with a camera tripod and the AXT1 tripod adapter. The AX2's rugged nylon housing is waterproof, wind resistant and features our new anti-wobble design. Experimenters will appreciate the AX2's versatile design. A removable cover allows access to the high-Q inductor. Simply remove the windings and re-solder a wire to cover your favorite ribbon. Clip-off tabs are provided for ribbon identification. SPECSResonant Frequencies AX2: ~14 MHz (20 m) AXE1: ~7.2 MHz (40 m) Resonant frequencies may vary +/- 400 kHz or more due to variations in terrain,antenna height, body capacitance, and length of radial(s). Supplied Radial Wire AX2: 13 ft. (4 m). AXE1: 33 ft. (10 m). Includes spade lug. Max. Power 15 Watts. If RFI symptoms are observed, reduce power or move the antenna farther from the transceiver. Construction Corrosion-resistant whip and hardware; Lexan outer tube; high-Q inductors using #20 AWG high-temp enamel wire. Dimensions (approx.) Whip: 6” (15 cm) collapsed, 45” (115 cm) extended. Base unit: 2.5” (6 cm). AXE1 extender: 6” (15 cm). Weight AX2: 3.2 oz. (90 g). AXE1: 2.0 oz. (55 g).

SDT21 simple digital transceiverProduct no.: SDT21simple "digital" monoband transceiver SDT21
The goal of this project was the development of a simple to build CW monoband transceiver based on the direct superheterodyne principle with crystal control a la "PIXIE" or "Rockmite", but with much better technical data. To minimize the circuit effort, the concept should be as highly integrated as possible and realizable without hand-wound coils. Furthermore, for the SMD phobics, SMD placement was completely omitted this time. Despite these specifications, it was possible to fit the entire circuit on a double-sided PCB with dimensions of 69x52mm, which allowed it to be installed in the small TEKO A2 package. The main focus of the circuit is based on the little known fact that digital inverters or gate devices of the 4000 CMOS series can be operated as analog amplifiers by a circuit trick, important here is the use of the unbuffered IC variant (index UB).
Please order the desired "set of band specific parts" according to the desired frequency! |
Schurr-Profi MProduct no.: Schurr-Profi MSchurr Profi M by Stefan Bergsiek Schurr-Profi M Stainless steel polished V2A Niro Dimensions 100x80x28mm Special edition stainless steel
The paddles are mounted backlash-free with hardened cylindrical pins in brass plain bearings. Due to this connection the bearing is absolutely maintenance-free! The advantage of this paddle bearing is that, unlike a ball bearing, no gumming up can occur over the years and the bearing can fail or become stiff. Any adjustment of this paddle bearing is not necessary. Hard silver contacts as well as fine thread are standard. 319€ Christmas offer |

SOTA Schurr Wabbler designed by Stefan BergsiekProduct no.: SotaWabblerSOTA Schurr Wabbler by Stefan Bergsiek small portable key from Schurr / Bergsiek gold plated about 170g No springs are installed. The paddle reset is made by magnets The paddles are mounted without play with hardened cylinder pins in brass sliding bearings. Due to this connection, the bearings are absolutely maintenance-free! The advantage of this paddle bearing is that, unlike a ball bearing, no hardening over the years can occur and thus the storage can fail or become difficult. Any adjustment of this paddle bearing is not necessary.
