TS-570D - CAT

At the first, i was manage to buy the Cat cable but when i tried to homebrew the cable & finally i success to make it..so now & so on my ts570d was control by computer..using DB-9 straight cable to com port at computer..the ts570d can do a very good job..can work well using Hams Radio Deluxe or RCP control..you can look video at below to 'walk through' the inspirations..

Recording on 40m

With Tx EQ 'Bass Boost'

Audio record done by 9m2bal, thank you very much..after i heard my own audio, i was realize the audio not enough energy & weight..right now i have to do some adjustment on the 'audio chain'..i need to workout on this matter to make sure the audio nice to hear outside there..hi hi..may be a few adjustment on EQ to suit with the current rig (only 2.4kHz bandwidth)..hope after this can get nice audio report from all of you there..

Isolation

Messy wiring

RFI Choke

There are many solutions for reduce/cut Mr. Ruffy (RFI) from enter to the transceiver..at the first step, i just make turn & put Toroid Snap at the turn to make RF/humming choke..& the result i got, RFI no more coming into my rig..so, i apply same method to each connections..below are the solution can be use for RFI/humming problem :

1. add Mix #31 Ferrite cores to the Microphone cable at each end, and in the middle..

2. mic cable is wired in a Balanced configuration..

3. change the microphone cable to a good quality cable like Canare or Mogami Starquad.. Whatever brand, be sure to get the Starquad..

4. shorten the mic cable to the minimum length necessary..

5. add a .001uf cap from the #2 Pin to #1 Pin, and a .001uf cap from the #3 pin to the #1 in the XLR connectors of the mic cable for RFI bypass..
