In rare cases, the TX monitor On/Off status is not backed up.
Updated items : (Version 1.22 1.23) Īfter directly entering the frequency, the bandscope marker position might not be updated correctly under certain conditions. Updated item : (Version 1.23 1.24) Īn error message (ERR:005C) may be displayed due to false detection, even though there is no failure in the transmitter circuit (FETs, ICs, Relays, etc.). Revises the expanded memory channels (E0~E4) default values according to the band plan.

Reduces TX/RX switching noise in CW full break-in operation in the sub band. Improves the power supply circuit control in order to reduce the standby power consumption at transceiver power turned OFF when Advanced Menu No.22 "Standby State Low Power Consumption" is "Off" from 20W (approx) to 12W (approx).

TS-990S owners can update the transceiver’s firmware by using a USB flash drive (or a PC connected via a USB cable) as detailed below. Charging: Built-in-In the lithium battery charging port, only the included charger can be used! It is forbidden to use other chargers!-Switch: off, Bat: built-in battery power supply, 13.8: external power supply-DC13.The TS-990S firmware has been updated from Version 1.24 to Version 1.25 as follows. Three switchable analog faders independent of the front receiver (0db, -13db, -20db, -33db, -53db, -60db, -73db)-Mds receiver noise level: -135dbm (200hz bw) at 28mhz-Front receiver selectivity: steep frequency adjustment -45db/ten times roll-off +/- 2khz -blockingDynamic range: 20khz offset 123db, 2khz offset 78db-Cw decoder, straight / iambic-a /b keying -Vfo a/b + rit and frequency division, and switch the corresponding relay with filter through i2c-Cat support (TS480 subset), can stream audio, keystrokes and display text via cat

Key shaping circuit pa)-All-digital and software-based sdr receiver stage (optional): sample the i/q signal (complex) from the quadrature sampling detector digital mixer, and perform a 90-degree phase shift (Hilber transform) in software And remove a sideband by adding Lightweight, low-cost transceiver: Thanks to the eer electronic level transmitter, it has high power efficiency (no need for bulky heat sink) and simple design (no need for complex balanced linear power amplifiers)-Ssb transmitter phase based entirely on digital and software: control the phase of the si5351 pll (via a small i2c frequency change exceeding 800kbit/s) and the amplitude of the pa (via from pwm to pwm) to test the microphone input and reconstruct the ssb signal. Open source firmware, built into ide allows experimentation, can add new features, can share contributions through github, software complexity: 2000 lines of code-V-based software can be used for fast complete rogue operations (qsk and semi-qsk), or auxiliary execution in digital mode (without cat or ptt interface) for rx/tx switch, with tx/pa delay control External ptt output-Simple installation and modification, 8 component changes and 8 wires

Eer e-level drive ssb launch stage-13.8v power source about 10w ssb pep output-Full mode support: usb, lsb, cw, am, fm-dsp filter: 4000, 2500, 1700, 500, 200, 100, 50hz passband-dsp function: control automatic gain (agc), noise reduction (nr), voice trigger, voice trigger xmit, attenuator rx (att), tx noise gate, tx driver control, volume control, dbm/s-meter-Ssb reverse sideband/carrier suppression transmission: better than -45dbc, imd3 (dual tone) -33dbc, reception: better than -50dbc -Multi-band support, continuously adjustable in the 160m-10m frequency range (with loss of 20khz performance ).
There is no need for complicated transformer windings, and no wiring procedures, the most cost-effective and easy to construct. The original qcx circuit is greatly simplified, and the installed components are reduced by 50%. Aluminum laser shell marking, all aluminum buttons, translucent silicone keys.4. Can be used to connect the antenna (meter base).3. This QRP SSB/CW shortwave transceiver has a 1602 screen, built-in battery, equipped with a charger, built-in microphone, speaker, can be connected to an automatic key, and can also be CW decoded.ġ.
