The problems included: water damage, antenna failure, damaged antenna (QBG), dropped and broken due to star connection issues, damaged during disassembly, and general mishandling.
I can accept various types of defective GX8500 units.Limited to one unit
For circuit reference and technical research.
Main research areas include: amplifier architecture, pre-amplifier parameters, operational amplifier (op-amp) adjustment parameters, heat dissipation structure, etc.
I do not accept new machines; I will not buy any new models.
FundamentalsRequirements: The operational amplifier (op-amp) circuit should not undergo significant modifications, such as completely removing the bias resistor or disconnecting a resistor without knowing its location.
MyselfOffer of 100 RMB, depending on the extent of damage; price negotiable.
NegotiationNegotiable range: x ∈ [0, 180] (Unit: Chinese Yuan/RMB)
Statement:
1. To reduce research and learning costs, the purchased radios are to be returned after the research is completed.It may be re-sold in the used market after undergoing repairs., detailed repair information will be provided at the time of sale.
2. This acquisition will be cancelled at any time as progress is made, and a notice will be posted on this thread to inform everyone.
