What you will get installed in transceiver:

✔ complete and fully functional mcHF SDR TRx (rev. 0.4 PCB with all the changes mentioned below)

✔ rubber quality knobs (see product pictures, color may vary*), for all 3 x encoders (M1/M2/M3)

✔ Visaton genuine SC-4.7 ND speaker, for quality audio

✔ quality finished black aluminiu case with back-stand

✔ quality aluminium navigation-encoder knob

✔ LCD touch-screen activated

✔ full-power capability, over 10W in almost all hf bands (160-10m)

✔ robust construction, with genuine quality parts from EU distributors (Mouser, TME, Farnell, SOS Electronic etc.) – easy replacement, if necessary

✔ XTAL (30ppm) stability for freq. measurement and generation

✔ SW settings already implemented, upgrades possible via USB / Flash-disk

HW modifications implemented, in order to increase the overall performance:

All mcHF transceivers assembled, tuned and sold by roWaves have the HW mods implemented.

For UI board:

1. UI-04-N-004 HY28A Display vs. HY28B Display Changes
2. UI-04-N-025 / UI-05-N-025 / UI-06-N-025 Switch LCD to SPI mode
3. UI-04-N-026 Activate touchscreen (recommended to use actual FW features)
4. UI-04-N-006 Display Dimming Interference Reduction
5. UI-04-N-008 Better Power Supply Filtering
6. UI-04-N-020 Simplified Bootloader Reprogramming
7. UI-04/05/06-N-019 Fit/Replace U7 EEPROM
8. n/a – electret condenser microphone correct biasing and activation (supressed “click” and “thump” noise when PTT is pressed)

For RF board:

1. RF-04-N-001 PA Overshoot
2. RF-04-N-002 PA RX Quiescent Current Reduction
3. RF-04-N-005 I/Q Signal Phase Improvement
4. RF-04-N-018 RX Sensitivity Improvement
5. RF-04/05/06-H-029 – relay switching for PA/Rx path (replacement for PIN diode switching)
6. RF-04/05/06-N-023 SWR Meter Operation Improvement
7. RF-04-N-011 Reduce standby current
8. RF-04-N-012, RF-04-N-022 Correct unsymmetrical ADC in the SWR measurement
9. F-04-N-015 – replacement for T5 transformers
10. RF-04-N-016 Replace RFC5 and RFC6
11. S53DZ status report 01 – T2 & T3 transformers central turn changed from CuEm wire to RG-316 coax wire for better SWR measurements
12. S53DZ status report 02 – replacement of old T7 transformer, from 1 x BN43-202 to 2 x BN43- 202, PRI & SEC with teflon wire, 270pF in parallel with PRI, decoupled by 100nF
13. S53DZ status report 03 – LM2931 resistor mod. (2.2kΩ between pin 1 & 4) for correct biasing of PA MOSFETS
