Ventura County - Purple EV-20, NAC: EE6

Thank you everyone for your excellent recommendations! I think I'll try the remote operation first to see if the radio is functioning normally. I am fearful of using vinegar on the radio even though it's a mild acid (to neutralize the alkaline battery leakage). I have not separated the circuit...

Darn! I cleaned up obvious areas of corrosion in the capacitor areas, but no joy (yet). Super sad! I can see where the battery corrosion has migrated into areas under the painted warning label. I will have to really try to clean it up. Maybe a bad investment on my part, not knowing how...

Well, I opened the unit last night and hate to say, that I "think" I see some possible corrosion in the area of C383, C361, C365, C355 and only maybe in the area of C394, C388, and C395. I may take a mini q-tip with alcohol to see if I can clean the area at all... The microprocessor...

Thank you tvengr! I will give this a try too. I just wanted to see if there might be a smoking gun that could have caused the sudden loss of contrast but will give your suggestion a try too!

Hello 737mech! Many thanks for your reply! I have not verified if the previous owner opened the radio or not. I will start my exploratory tonight. I need to first see if any traces on the double-sided PCB on the battery compartment side (Linear Board?) might be damaged from the corrosion...

I purchased a supposed used in excellent condition PSR-500. It had minor battery leakage damage inside the battery compartment in the middle-upper left side (on the black printed warning inside the compartment. Looks like the previous owner scratched some of the leakage corrosion away. I am...

I tried the Hyperterminal test (WinXP) using COM1 and COM19 (the USB-RS-232 adapter) and did not have any luck. I will try another computer (Win10) today. Frustrating!

I still need to run the test sequence that you provided, but thought I'd report the operation of the USB-to-Serial adapter with the CPS. When I install the drivers and run CPS, the CPS recognizes the adapter and new available COM port (in this case COM19). Sadly though, I still get the "radio...

Thank you for the info. I will give it a try. As another parallel effort, I am going to try a USB to RS-232 adapter to see if that opens up the communication between laptop and radio. I will keep you posted... Steve

Hello! I am looking for programming help with a mid-power XTL5000, O3, Remote Mount radio with the HKN6061B cable. For some reason I am getting a Radio Failed To Acknowledge error, reading or writing to the radio. I have the Serial Port at 9600 baud (N-8-1), and the CPS set to COM1. I know...

Hello EFJ Experts! Is there a way to edit an existing PC Configure (5100ES) codeplug to append Zones from another codeplug? I am trying to minimize my programming effort by essentially "cutting and pasting" Zones from another codeplug into another radio with a different codeplug. I thought I...

Update - New ICIS system members Ooops! Where have I been!?!? I just saw that Santa Monica recently joined ICIS... Got it! Thanks!

Does anyone have the current Santa Monica PD and FD frequency list and NACs? I seem to be hearing multiple modes on some of their 'channels' and was curious if they might have different groups using the same frequency but with different modes (analog, P25, DMR?). I tried 'sniffing' the...

WTB: MA350ED I have an old OAR (Ocean Applied Research) receiver that has the VHF only version antenna that I believe has the same interface as the MA350ED. Works great on VHF - I'd like to get the UHF band covered. Steve

Curious if anyone has seen any surplus MA350ED (or similar) RDF Adcock style antennas for sale. I have an old DF receiver with a VHF only antenna array and I was hoping to find an MA350ED antenna to expand my capabilities into the UHF bands also. Just curious if any have surfaced recently. I...

Surprised at this sad news... I also missed this sad announcement. "Ditto" on all the great things folks have said about Ko. He and I did some radio 'horse trading" over the years, and every transaction was a pleasant one. What a sad surprise to see this announcement about one of the good...

China Lake NAWC Ground Comms Last time I visited the site, I brought my Pro-96 and scanned around the low portion of the VHF band. I did find some conventional analog traffic there, and also found some P25 comms there too. There were some P25 comms in the clear, and some that were encrypted...

Curious where the previous conventional VHF China Lake NAWC / NAWS communications went. Used to listen to the activity on the base bu now not a peep. Did they go to a P25 trunking system possibly? Thanks very much for any help! Steve KC6IJM

I sent Anthony, EMS1983, a new leather holster for his Jedi radio, a new Jedi speaker mic, and a new VHF antenna for same. He said he was going to send me an EF Johnson Radio Programming interface box in trade. Once I sent my package to him, he stopped responding to any of my e-mails. Do you...
