A1. We have 1 year warrantee, If any quality problems on our side occurred in this period, we will take on replacement.
Q2. What is the difference between super regeneration and super heterodyne?
A2. There is advantage and disadvantage no matter it is super regeneration or super heterodyne.
Super regeneration is more economic on the cost, and its sensitivity is high, but its frequency will flow up and down affected by the temperature, and its anti-interfere capacity is not so good as super heterodyne. While super heterodyne is stable on its frequency, and its capacity of anti-interfere is better than super regeneration, and its working with the MCU is more stable, but its sensitivity is not so good as super regeneration, and the cost is higher too, besides, it is possible signal jam in short distance when the signal is strong.
Q3. What is ASK and FSK?
A3. ASK is Amplitude Shift Keying, FSK is Frequency-shift keying. Simply speaking, ASK uses different amplitude to represent 0 or 1, while FSK uses different frequency range to represent 0 or 1. The anti-interfere capacity of FSK is better than ASK, and its range is longer than ASK too.
Q4. What attention need to pay when order the remote?
Q4. Need to make clear which IC is need, because it concerns the pair with the receiver. The same plastic case can have different IC inside.
Q5. What attention need to pay when order the receiver?
A5. Need to clear if super regeneration or super heterodyne is needed.
Q6. What is the payment term?
A6. For samples, paypal is more economic, for order, we can accept T/T or Western Union.
Q7. What is the shipping method?
A7. FedEx/DHL/UPS/TNT for samples or light parcel, Door-to-Door
By air or by sea for heavy parcel or batch.
Q8. What is the Delivery time?
A8. 3-5 working days for samples, and 15-20 working days for orders.
