[Amps] Amp for 444 mHz

[tz4am at aol.com]

Thanks Roger. All good questions. Base station like net control. Duty cycle not more than 30%. Others have suggested remoting amp to the rooftop location near the antenna.  With that, I think even 100 watts would be fine.

SSB? FM? Digital?  What kind of duty cycle?  Mobile or home station?I'm assuming (which is never safe) you want SS.If you are willing to go new there are a number of  SS amps available for FM.  A quick search should turn up quite a few in the 10 to 50W drive and 160 out range. There are a few in the 200W range and it "seems" as if I remember seeing one with 300W out.Back in the 70s I had a complete, self contained, 600W out SS amp.  Wish I'd kept it.Now if you want AB1 for SSB, there are some new SS amps that run up to a KW out, but they are definitely not inexpensive.There are also tube amps that run from 800 to the legal limit. Again a search might find some, new and/or used.There are the Old Henry tube amps that use a 3CX800 that occasionally show up for sale.Availability in EU?  Import duty, VAT, and shipping might make one from the US pretty expensiveIIRC there are several companies in the EU building tube and SS high power VHF amps. Again, not cheap.Good Luck.73, Roger (K8RI)On 2/27/2018 Tuesday 3:02 PM, Jeff Dorsey via Amps wrote:> Dear All:>>> I need an amp for 444 mHz band, somewhere between 100 and 400 watts output, preferrably from EU but also possibly from USA.>>> With kind regards,>>> Jeff>>>> tz4am at aol.com>> _______________________________________________> Amps mailing list> Amps at contesting.com> http://lists.contesting.com/mailman/listinfo/amps>-- Roger (K8RI)---This email has been checked for viruses by Avast antivirus software.https://www.avast.com/antivirus_______________________________________________Amps mailing listAmps at contesting.comhttp://lists.contesting.com/mailman/listinfo/amps
