I have a VHF spectra Model #: D43KXA7JA4AK

I tested the radio prior to installing/wiring. After installing and wiring, tested again, original information was in radio. Read the radio---re-wrote with new information---after self check, all the info was there and working fine.

Antenna was not yet screwed into main---the mic was accidently keyed, after shutting down the radio and turning back on, the following error code is displayed " fl 01/90 " and the radio shuts off and tries to self check and the error comes up and repeats the following procedure. I disconneted the remote head, disconnected the power supply from battery---still no luck. Tried to read the radio, get serial bus error, tried to write the saved codeplug---same bus error.

Is this radio fried? What can I do to recover the radio??

Thanks

fail 01/90 can be caused by a blown fuse or disconnected dc power + lead what control head are you using? I forgot to put a fuse in the main power when I installed my 900 spectra got the same error also what size fuse is in the main power lead? my radio is a system 9000 with an A9 head.

I found the inline 4amp fuse blew----would that be due to no antenna being hooked up or do I have something else going on?

Was this fuse on the power line to the radio deck or to the control head. If to the radio deck it should be a 20 amp. The fuse for the control head is the 4 amp. It's possible, if you pruchased the radio from someone else, that the fuses were switched. If this is the case then I assume that you never tried to trnasmit when it was hooked up on the bench.

Make sure the fuses are in their correct locations. If they are I don't think the transmitting power is sensed anywhere in the control head circuitry so it may be a faulty control head but you only see the fault when transmitting

cduda, I know we talked offline but I wanted to keep the thread going also.

As I said in my reply there should be 2 fuses if you are using a remote head. Actually since it is a spectra there should be 2 fuses no matter what. One, the main fuse for the radio itself, is a 20 amp. The other, for the control head operation, is a 4.

The 20 is in the mainline and is usually close to the battery. The other should be on a single red wire that eventually leads to a DB9 connector. If it is a remote head then is will mate with a pigtail from the head. If it is a dash mount radio then the DB9 goes right into the 9 pin accessory connector on the back of the radio.

Hope this helps.

For a remote mount you should have 3 fuses. For the model mentioned there should be a 15A fuse for the main power lead, and two 3A fuses for the control head orange and green leads.

Also the accessory connector is a DB15 not a DB9 the remote mount spectra has 2 wire green & orange green goes to battery the orange gotos to a point that is hot only when the key is on both the orange and green are fused seprately with 4 amp fuses.

That's right it is a 15 pin His model, D43KXA7JA4AK, should be a spectra. The Astro Spectra uses the green and orange wires and the fuses on those you usually have to install yourself. They are also not the auto type fuses but the glass/ferrule type.

Sorry about the confusion on the connector but I think the only problem is someone switched the fuses or thought they should both be 4 amp

Jack IS correct.
Main power fuse is 15A MAX (for a mid power drawer).
The IGN fuse on a A4, A5 or A7 Spectra IS 3A... or on an A9 the 'Orange' and 'Green' leads are each fused at 3A MAX.

Reason: The circuit traces, reverse polarity diode, ect, can not handle any more than the three amp fuse before burning the circuit traces, ect..

I'll point out again that I believe the OP is working with an analog spectra. The model number he posted was D43KXA7JA4AK which I believe is a spectra and thus will not have the orange and green wires.

Is there such a thing as a low, mid, high power difference now? From what I can see there are up to 11 different power ratings ranging from 0-.7 to 61 to 110 for an Astro spectra.

And why have I received all my astro spectras with a 20 amp fuse installed in the main line fuse? I suppose it is because we ordered the 36-60w model, D04JKF9PW5AN, but in the install manual it shows a 15 or 40 amp fuse. I'm confused now.

To get back to the original question, the mainline fuse should be something larger than 4 amps.

Yes, we're talking regular Spectra, not Astro.

An A4 remote mount Spectra most certainly will have the orange and green wires.

This is the setup I am referring to. As I deal with the military this may be something that only they use.

Jack that is the later so-called X9000 cabling. Later X9000 Spectras came with the cabling shown in the diagram.

The one shown in the photo is the standard style Spectra.


These are AKA "mid" power like the one in misawatech 's photo:

VHF 10 to 20 watts x33xxA series short heat sink
VHF 30 to 50 watts x43xxA series
UHF 6 to 15 watts x34xxA series short heatsink
UHF 20 to 40 watts x44xxA series
800 15 watt short heatsink
800 35 watt
900 12 watt short heatsink
900 30 watt

Hmmm.. I've never seen the old style, all of the remote mounts I've dealt with (mostly x44xxA models) have been the 9000 style with the HKN4356B cable (which is what is listed in my service manual for the model in question), new one on me...
Now I'm curious to know which one cduda has, perhaps he'll post back.

I'd like him to post again also. It seems we took over the thread and he hasn't been back.

I wonder if you haven't seen this model, and he may not have it, due to the encryption box? It seems that the other spectras we have, none of them remote mount though, have the encryption installed in the radio unit not a separate piece of equipment.

I'm new to radios and limited in the equipment I see, although it is a lot, so I just assumed this was the norm.
