[NLRS] [NTMS] FlexWire interface for the Flex-1500

[Ed WB0VHF]

Al, John,


I understand the ease of talking vs. typing, but I, too, am interested 
in the end result. I hope to get 6M through at least 3456 on my 5000. My 
initial thoughts were to use XVTRs for 6M-70CM, then use the internal 2M 
of the 5000 to drive the rest of the XVTRs. Not sure if that is the best 
choice. I guess for John, the equivalent would be to have a second 2M 
XVTR to drive the high band XVTRs.


As for programming the transverter page, I thought it was a matrix of 
which relay(s) get activated for a given band. If that is the case, then 
you could have one output for the 2M XVTR, and a different one for the 
2M amp. On 2M, both get set, one high bands, only the XVTR one for 2M 
goes, along with what you need for that higher band. At least that is 
how I thought it was supposed to work.


73,

I'm not ready to heat up the soldering iron yet, but while enduring this intolerable delay in getting the concrete foundation poured for my tower, I am trying to use the down time to "get all my ducks in a row" with respect to everything else I need to prepare for my re-incarnated station (move from Minnesota to Texas).

My configuration is going to be complex, because I am planning to eventually use the Flex-1500 on at least 6 bands, 902 through 10368, and possibly 10 bands if I choose to also use it for 50/144/222/432. There is not going to be a simple 1:1 correspondence between a band and a single relay. For example, if I run 2 meters on the Flex-1500, I will select the 2 meter transverter plus the 2 meter power amplifier, but if I select the 1296 band, I will need to connect the Flex to the enabled 2 meter transverter, but instead of going to a 2 meter power amplifier, the 2 meter transverter will connect to an enabled 1296 transverter instead. If I include the 4 lower bands also, it gets even more complicated because the Flex-1500 would either be talking to a single transverter on one of the low bands or to the 2 meter transverter and then the higher band transverter. I suspect it's something simple, just not written down in the documentation of the K3TUF board nor in the user manual for PowerSDR. Is the "UCB Address" on the transverter page simply a bitmapped value with ones in each position where a relay is to be activated? Or is it not possible for one transverter selection to activate multiple relays at the same time? (While annoying, that wouldn't be terrible, I'd just have to use one low-power DC relay's contacts to activate as many coaxial RF relays as necessary for a particular band...)
