Standby problems with the TM-D710

Standby problems with the TM-D710This morning it occurred to me my car almost didn’t start. The battery seemed almost dead. It couldn’t be the battery itself since it is about a year old. When I was thinking about it, I did noticed a low voltage in my battery before. It had to be standby problems with some device in the car.

Update 23cm trx

23cm TRXDid a lot of work the other night at the 23cm trx. Build in the speaker (drilled a lot of holes!) and did the last mod to do more filtering in the VCO voltage. Also fixed the phantom power for the electret microphone. Modulation and LF-sound are now in an acceptable range. There is always room for improvement, but at least I can leave this little puppy running in the background without scaring up every time some one opens the repeater.
Now I have my ‘reference rig’ I found out the filtering of the 23cm TRX is indeed under average. The reference rig can easily hear repeaters from miles away and doesn’t have a S6 to S7 noise without an signal. I think the UMTS-antenna that is about 50 meters away must have something to do with this. I think the next to do for this trx is building a bandpass filter.
