[TowerTalk] VA6AM triplexer and BPFs

[Tina Coker]

Hey Bill, I’ve got both triplexers from Pavel and 4O3A now for some different way’s I’m using my multi-mono’s with single feedlines. One set of 4O3A HPBPF’s too...
I’ve got them outside in a RubberMaid shed in So Cal. I’ve yet to run fans to any of them after hearing from a well known So Cal contest station that I guest op at that they haven’t had issues of overheating doing either SOHP or MSHP. I’m using mine doing SOHP with dual CQing.
Neither of the stations do serious RTTY contesting though... but if your shack is AC’d maybe it’s not all that necessary?
Then again you’re dealing with more humidity than us as we mainly deal with high temps.

Thanks to all who responded to my questions on triplexers and BPFs.


To the guys using the high power VA6AM...


I'll be solely SO2R, never M2.  So only one signal on the air at a time....legal limit (really)  The smaller fans are what I'm getting on the BPFs except for 10 M.  On 10 I'm getting the bigger one which I believe is 100CFM.  I know the smaller fans are pretty quiet, but the larger one is pretty noisy. 


Any thought s as to the necessity of the bigger fan for 10  and how noisy are the fans?  The whole set up will be under the operating desk in the kneehole.
