ANAN-G1 100 W KV and 6m SDR transceiver

Introduction

In the world of amateur radio broadcasting, Apache Labs strives to push the boundaries of technology performance and availability SDR (Software Defined Radio). One of their interesting products is ANAN-G1, 100 W HF/6 m SDR transceiver, ktorý je určený pre rádioamatérov, ktorí chcú kombinovať moderné digitálne spracovanie signálu s vysokým výkonom a spoľahlivosťou.

Architecture and main features

Jadro prístroja tvorí 16-bitový AD/DA prevodník, ktorý poskytuje pôsobivý dynamický rozsah a pomáha minimalizovať skreslenie pri príjme aj pri vysielaní. FPGA jednotka, konkrétne Intel Cyclone 10, zaručuje dostatočnú výpočtovú kapacitu pre DSP operations, management and multireceiver operation.

Preamplifier with a high dynamic range and filtering (e.g. TX bandpass filtering, BCB reject high-pass filter) ensures resistance to interference and strong signals. The entire device is housed in a robust aluminum construction, which also serves as a cooler, providing good thermal stabilization.

Performance and operating characteristics

Na KV a 6m pásmach dosahuje výstupný výkon až 100 W (for CW, SSB, FM, digital modes), while for AM mode it is possible to transmit in the range of 1–30 W.

Zariadenie podporuje štyri nezávislé softwarové prijímače (receivery), which can work simultaneously from one antenna (antenna sharing). Each of these receivers can display a spectrum with a width of 48, 96 or 192 kHz.

Okrem toho je možná plne duplexná prevádzka (with the possibility of different RX/TX in the entire range of 160 m to 6 m).

Immunity to unwanted signals is loosely expressed as imperceptible signal compression (gain compression) should not occur at levels below the overload threshold ADC.

Vysielací IMD (intermodulation distortion) at 10 W at 20 m typically reaches values ​​below –50 dBc (third order), which in practice means decent purity of the transmitted signal.

Technical specifications and parameters

• Pokrytie príjmu: 10 kHz až 55 MHz (in some versions up to 60 MHz)

• Architektúra: direct sampling DDC/DUC (direct sampling)

• Power supply: 13.8 V DC, maximum current in reception approx. 3 A, in transmission up to 25 A

• Dimensions: approximately 10.4″ × 3.11″ × 10.87″

• Weight: about 15.8 lb (about 7.2 kg)

• Receiver sensitivity: with built-in preamplifier and typical noise floor in the 500 Hz band -135 dBm

• Input attenuator: software adjustable from 1 to 31 dB in 1 dB steps

Software, control and extensibility

The device is controlled via Ethernet rozhranie, pričom FPGA firmware (kód) je možné aktualizovať cez TCP/IP sieť.

Podporovaný softvér zahŕňa OpenHPSDR platformu, najmä populárny balík Thetis (and also PiHPSDR) for control, spectrum visualization, DSP effects and control functionalities.

In addition, the G1 has seven user-configurable open-collector outputs that can be independently configured by band or TX/RX mode. These outputs are often used to control relays, switch antennas, switch power stages sequentially, and the like

Mikrofónne PTT (Push-To-Talk) can be jumpered to tip or ring cable and power is also provided for the electret microphone via a jumper.

Comparison of ANAN-G1 with the competition

1. Apache Labs ANAN-G1 vs. FlexRadio FLEX-6400

• Performance: oba ponúkajú 100 W na HF a 6 m.

• Architecture: G1 využíva FPGA Cyclone 10 a 16-bit AD/DA s direct sampling, FLEX-6400 má podobnú architektúru, no s väčšou integráciou a úzkym prepojením s proprietárnym softvérom SmartSDR.

• Receivers: ANAN-G1 zvládne 4 súčasné receivery, FLEX-6400 len 2.

• Software: FLEX je jednoduchší na použitie (SmartSDR, vzdialený prístup cez internet), ANAN je otvorenejší a flexibilnejší (Thetis, OpenHPSDR), no vyžaduje viac znalostí.

• Price: FLEX je drahší, G1 je cenovo dostupnejší pri podobnom výkone.

2. Apache Labs ANAN-G1 vs. Elecraft K4

• Performance: Oba ~100 W na HF/6 m.

• Receivers: K4 má modulárny koncept – základný model má 1 RX, rozšíriteľný na viac, G1 má hneď 4 RX.

• DSP and SDR functions: Elecraft K4 má moderný dotykový displej a lokálne ovládanie (bez nutnosti PC), G1 potrebuje počítač alebo externý klient.

• Flexibility: G1 je viac orientovaný na experimentátorov (otvorený softvér, community-driven), K4 je komerčne ladený s dôrazom na užívateľský komfort.

• Price: Elecraft K4 je výrazne drahší (dvojnásobok až trojnásobok).

3. Apache Labs ANAN-G1 vs. Apache Labs ANAN-7000DLE MkII

• Architecture: 7000DLE používa výkonnejší FPGA a má 8 RX, G1 je kompaktný model so 4 RX.

• Performance: Oba 100 W.

• Target group: 7000DLE je high-end pre contest a DX-ing vo veľkom štýle, G1 je menší brat – cenovo dostupnejší, ale stále veľmi výkonný.

• Dimensions and weight: G1 je ľahší a kompaktnejší, čo ocenia portable a menšie hamshacky.

Advantages, use and focus

ANAN-G1 it is designed to provide high performance and advanced SDR features at a price that is relatively competitive in the SDR world. It is the ideal device for radio amateurs who do not need more than 100 W of power, but want to use the modern advantages of SDR - flexible DSP on-the-fly, multiple receivers, software filters, automatic updates and advanced control.

Je vhodný na DX prevádzku, súťaže (contest), experimentovanie so slabými signálmi (weak-signal work), ako aj bežné denné používanie v KV a 6 m pásmach. Vďaka dobrej odolnosti k rušeniu a čistému výstupu môže byť aj v prostredí s množstvom signálov či silných blízkych vysielačov.

Potential disadvantages may be associated with the requirement for a powerful computer, a good network connection and familiarity with SDR software. Also, the packaging and cooling must be properly designed, as the power stages and internal components produce heat.

Conclusion

ANAN-G1 is a powerful and competitive SDR transceiver with a power of 100 W for KV and 6 m bands. Thanks to advanced hardware (16-bit AD/DA, FPGA), support for multiple independent receivers, full duplex operation and reliable construction, it is an interesting choice for radio amateurs looking for a sophisticated platform capable of growing with their requirements.
