XTS5000 UCM how many keys can you load?

[saberthree]

I was screwing around with the UCM stuff on the XTS5000 and noticed that you can load up to 48 CKRs in CPS on hardware mode, however out of academic curiosity I decided to see how many keys I can actually load into the radio. It looks like each key set has a slot for 48 keys, I was able to load 3 key sets of 48 or 144 keys without any error codes. Using the same CKR numbers in each key set but individually labeling each key ID. Of course, it didn't actually work as far as being able to switch keysets and using the same CKR with a different key ID, it seems to just default to the first key set. Anyone have any insight to this? I was a bit surprised the radio didn't give me an error code when I started the keyfill. As an experiment, I deleted CKR 1 key on keyset 1 but it seems to delete the other key on CKR 1 slot in key slot 2 as well. Unfortunately, I'm still playing the waiting game for a KVL cable on for my other radio I want to test further asides from, using ADP with only 8 slots.

How is the key set supposed to actually work? How is it managed?
How does index work? i noticed in the manual as well, but It seems I don't have the ability to add it to the screen menu
Is it safe to assume I can only load 48 keys? I mean yeah I get it, how many keys do you really need in a radio?! Thanks to otar for the bigger companies and agencies.

I guess it's safe to assume you can only load 48 keys? I mean heck, if you use one key a month, that's enough keys for 4 years.

I know I have more than 48 keys loaded in mine...

were you able to confirm with another radio that your second keyset isnt defaulting to the first key set? I loaded over 140 keys in mine but it seems like its not actually letting me use the other keys in my other key sets

I've already seen that picture. It was one of the reasons why I decided to try and load 3 key sets of 48 keys each initially to see if I could do it. I tried using the second key set and it just ends up defaulting to the 1st key set, so I'm probably doing something wrong. I'm hoping someone here will enlighten me and show me how it's done. I've made individual key IDs for each keys and reused the CKRs for each key set. I assume when you switch key sets and use the CKRs, it should be fine with the key IDs being different. I tried deleting the keys in key set one but it seemed to delete the keys of the corresponding CKR in keyset 2 as well which I find strange. I don't know much about KVLs and UCMs, I'm just the user wanting to learn.

After reading the KVL4000 manual, I've come to a conclusion that to load more than 48 keys, you would most likely have to use a KVL in PID/ASN mode. I am using the KFD, which doesn't support the PID/ASN mode. The KFD only supports astro25/CKR mode, so I am limited to only 48 CKRs. I'm sure down the road PID/ASN will be supported on the KFD. I believe the mystery is solved

I think I figured it out, I was reading the KVL4000 manual, it says it can load 1024 keys but only in ASN/PID mode which unfortunately the KFD I am using is not supported (yet)
