[Repeater-Builder] exec I vs exec II
Anyone have a "short version" of the differences between an exec I station and an exec II station? Are the innards swappable? Thanks for your time. Chris Kb0wlf
Re: [Repeater-Builder] exec I vs exec II
Basically the name and the general form factor are the only similarities. The hardware is completely different. 2 different generations of design. Nothing interchangeable except the microphone and that is only on some of them. Later mics on exec II were different Doug At 05:06 PM 3/3/2009, you wrote: >Anyone have a "short version" of the differences between an exec I station >and an exec II station? >Are the innards swappable? > >Thanks for your time. > >Chris >Kb0wlf

I think the exec I had a tube final RX was solid state looks nothing like an exec II so I would say no. tom > [Original Message] > From: Chris Curtis > To: > Date: 3/3/2009 5:06:57 PM > Subject: [Repeater-Builder] exec I vs exec II > > Anyone have a "short version" of the differences between an exec I station > and an exec II station? > Are the innards swappable? > > Thanks for your time. > > Chris > Kb0wlf > > > > > > > > Yahoo!

Correct.The exec 1 had totally different innardsthe exec II is similar to the Mastr II The exec 1 had three tubes8106, x 2and 7984 PA John VE3AMZ - Original Message - From: "Thomas Oliver" To: Sent: Tuesday, March 03, 2009 5:29 PM Subject: RE: [Repeater-Builder] exec I vs exec II >I think the exec I had a tube final RX was solid state looks nothing like > an exec II so I would say no. > > tom > > >> [Original Message] >> From: Chris Curtis >> To: >> Date: 3/3/2009 5:06:57 PM >> Subject: [Repeater-Builder] exec I vs exec II >> >> Anyone have a "short version" of the differences between an exec I >> station >> and an exec II station? >> Are the innards swappable? >> >> Thanks for your time. >> >> Chris >> Kb0wlf >> >> >> >> >> >> >> >> Yahoo!

Re: [Repeater-Builder] exec I vs exec II
The MASTR Exec (1) came in two flavors (at least here in Canada), the Exec with a tube final and the Royal Exec with a solid state final. The receivers in both cases was very similar. The receivers are very sensitive and also quite tough. I saw one where the input trace on the circuit board had evaporated due to an arc (from induced lightning) to the case 1/8 inch away. Jumpered the trace and the RX sensitivity came back to normal. BTW the Exec receiver makes a very good 220 receiver. The majority of 220 repeaters here in the Montreal area use them.

I had a VHF Exec & I'd say the front-end had the dynamic range of a typical amateur grade mobile radio. IF bandwidth is also wider than the Mastr II. But yes they are more sensitive than a stock Mastr II. >BTW the Exec receiver makes a very good 220 receiver. The majority of >220 repeaters here in the Montreal area use them. Makes sense - with no helicals to cut down they would make an easy conversion. Bob NO6B
